The value of -keypass is a password used to protect the private key of the generated key pair. The password must be provided to all commands that access the keystore contents. How do request a SSL cert for reissuing if we lost the private key? The startdate argument is the start time and date that the certificate is valid. To Delete a Certificate by Using keytool Use the keytool -deletecommand to delete an existing certificate. Public key cryptography requires access to users' public keys. Use the importkeystore command to import an entire keystore into another keystore. Before you import it as a trusted certificate, you should ensure that the certificate is valid by: Viewing it with the keytool -printcert command or the keytool -importcert command without using the -noprompt option. The keytool command can create and manage keystore key entries that each contain a private key and an associated certificate chain. How to remove and install the root certs? If -keypass isnt provided at the command line and is different from the password used to protect the integrity of the keystore, then the user is prompted for it. To finalize the change, you'll need to enter your password to update the keychain. Solution 1. First, convert the keystore from JKS to PKCS12 (this and other commands will require password entry): keytool -importkeystore -srckeystore old.jks -destkeystore old.p12 -deststoretype pkcs12 Next, export a PEM file with key and certs from the PKCS12 file: openssl pkcs12 -in old.p12 -out pemfile.pem -nodes This means constructing a certificate chain from the imported certificate to some other trusted certificate. The keytool commands and their options can be grouped by the tasks that they perform. This period is described by a start date and time and an end date and time, and can be as short as a few seconds or almost as long as a century. If the original entry is protected with an entry password, then the password can be supplied with the -keypass option. This is a cross platform keystore based on the RSA PKCS12 Personal Information Exchange Syntax Standard. An alias is specified when you add an entity to the keystore with the -genseckey command to generate a secret key, the -genkeypair command to generate a key pair (public and private key), or the -importcert command to add a certificate or certificate chain to the list of trusted certificates. A keystore is a storage facility for cryptographic keys and certificates. Commands for Creating or Adding Data to the Keystore: Commands for Importing Contents from Another Keystore: Commands for Generating a Certificate Request: Commands for Creating or Adding Data to the Keystore. That is, there is a corresponding abstract KeystoreSpi class, also in the java.security package, which defines the Service Provider Interface methods that providers must implement. If -destkeypass isnt provided, then the destination entry is protected with the source entry password. If you dont specify a required password option on a command line, then you are prompted for it. However, the trust into the root's public key doesnt come from the root certificate itself, but from other sources such as a newspaper. The -gencert option enables you to create certificate chains. If NONE is specified as the URL, then a null stream is passed to the KeyStore.load method. The following examples describe the sequence actions in creating a keystore for managing public/private key pairs and certificates from trusted entities. Java Keytool is a key and certificate management tool that is used to manipulate Java Keystores, and is included with Java. The user must provide the exact number of digits shown in the format definition (padding with 0 when shorter). The CA trust store as generated by update-ca-certificates is available at the following locations: As a single file (PEM bundle) in /etc/ssl/certs/ca . Its useful for adjusting the execution environment or memory usage. All X.509 certificates have the following data, in addition to the signature: Version: This identifies which version of the X.509 standard applies to this certificate, which affects what information can be specified in it. Use the -importkeystore command to import a single entry or all entries from a source keystore to a destination keystore. Used to specify the name of a cryptographic service provider's master class file when the service provider isnt listed in the security properties file. If a password is not provided, then the user is prompted for it. Provided there is no ambiguity, the usage argument can be abbreviated with the first few letters (such as dig for digitalSignature) or in camel-case style (such as dS for digitalSignature or cRLS for cRLSign). Once logged in, navigate to the Servers tab from the top menu bar and choose your target server on which your desired application/website is deployed. If the reply is a single X.509 certificate, keytool attempts to establish a trust chain, . In Linux: Open the csr file in a text editor. The following are the available options for the -delete command: [-alias alias]: Alias name of the entry to process. Running keytool only is the same as keytool -help. If the certificate isnt found and the -noprompt option isnt specified, the information of the last certificate in the chain is printed, and the user is prompted to verify it. Otherwise, -alias refers to a key entry with an associated certificate chain. If such an attack takes place, and you didnt check the certificate before you imported it, then you would be trusting anything that the attacker signed. If the -trustcacerts option was specified, then additional certificates are considered for the chain of trust, namely the certificates in a file named cacerts. If you have a java keystore, use the following command. The value of -startdate specifies the issue time of the certificate, also known as the "Not Before" value of the X.509 certificate's Validity field. To import a certificate from a file, use the -import subcommand, as in. Now a Certification Authority (CA) can act as a trusted third party. If the -rfc option is specified, then the certificate contents are printed by using the printable encoding format, as defined by the Internet RFC 1421 Certificate Encoding Standard. This old name is still supported in this release. Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site It protects each private key with its individual password, and also protects the integrity of the entire keystore with a (possibly different) password. The keytool command also enables users to administer secret keys and passphrases used in symmetric encryption and decryption (Data Encryption Standard). Currently, two command-line tools (keytool and jarsigner) make use of keystore implementations. 1. We use it to manage keys and certificates and store them in a keystore. It is assumed that CAs only create valid and reliable certificates because they are bound by legal agreements. You can enter the command as a single line such as the following: The command creates the keystore named mykeystore in the working directory (provided it doesnt already exist), and assigns it the password specified by -keypass. It generates v3 certificates. The new password is set by -new arg and must contain at least six characters. Constructed when the CA reply is a single certificate. The keytool command doesnt enforce all of these rules so it can generate certificates that dont conform to the standard, such as self-signed certificates that would be used for internal testing purposes. The following are the available options for the -printcert command: {-sslserver server[:port]}: Secure Sockets Layer (SSL) server host and port. The command reads the request either from infile or, if omitted, from the standard input, signs it by using the alias's private key, and outputs the X.509 certificate into either outfile or, if omitted, to the standard output. You use the keytool command and options to manage a keystore (database) of cryptographic keys, X.509 certificate chains, and trusted certificates. Java tool "Portecle" is handy for managing the java keystore. Because the KeyStore class is public, users can write additional security applications that use it. java.home is the runtime environment directory, which is the jre directory in the JDK or the top-level directory of the Java Runtime Environment (JRE). However, you can do this only when you call the -importcert command without the -noprompt option. Identify the alias entries that need to be deleted using keytool list command. If the -keypass option isnt provided at the command line and the -keypass password is different from the keystore password (-storepass arg), then the user is prompted for it. From the Finder, click Go -> Utilities -> KeyChain Access. See the -certreq command in Commands for Generating a Certificate Request. You can then stop the import operation. Entity: An entity is a person, organization, program, computer, business, bank, or something else you are trusting to some degree. If you later want to change Duke's private key password, use a command such as the following: This changes the initial passwd to newpasswd. If no password is provided, and the private key password is different from the keystore password, the user is prompted for it. Select the Edit Certificate Chain sub-menu from the pop-up menu and from there choose Remove Certificate. Later, after a Certificate Signing Request (CSR) was generated with the -certreq command and sent to a Certification Authority (CA), the response from the CA is imported with -importcert, and the self-signed certificate is replaced by a chain of certificates. If it detects alias duplication, then it asks you for a new alias, and you can specify a new alias or simply allow the keytool command to overwrite the existing one. An error is reported if the -keystore or -storetype option is used with the -cacerts option. When-rfc is specified, the keytool command prints the certificate in PEM mode as defined by the Internet RFC 1421 Certificate Encoding standard. Importing Certificates in a Chain Separately. This is because before you add a certificate to the list of trusted certificates in the keystore, the -importcert command prints out the certificate information and prompts you to verify it. When there is no value, the extension has an empty value field. In the latter case, the encoding must be bounded at the beginning by a string that starts with -----BEGIN, and bounded at the end by a string that starts with -----END. Use the -importcert command to read the certificate or certificate chain (where the latter is supplied in a PKCS#7 formatted reply or in a sequence of X.509 certificates) from -file file, and store it in the keystore entry identified by -alias. In some cases, such as root or top-level CA certificates, the issuer signs its own certificate. The full form is ca:{true|false}[,pathlen:len] or len, which is short for ca:true,pathlen:len. In a typical public key crypto system, such as DSA, a private key corresponds to exactly one public key. The cacerts file represents a system-wide keystore with CA certificates. localityName: The locality (city) name. Because there are two keystores involved in the -importkeystore command, the following two options, -srcprotected and -destprotected, are provided for the source keystore and the destination keystore respectively. During the import, all new entries in the destination keystore will have the same alias names and protection passwords (for secret keys and private keys). Certificates are used to secure transport-layer traffic (node-to-node communication within your cluster) and REST-layer traffic (communication between a client and a node within your cluster). The subjectKeyIdentifier extension is always created. Validity period: Each certificate is valid only for a limited amount of time. All keystore entries (key and trusted certificate entries) are accessed by way of unique aliases. Applications can choose different types of keystore implementations from different providers, using the getInstance factory method supplied in the KeyStore class. In some systems, the identity is the public key, and in others it can be anything from an Oracle Solaris UID to an email address to an X.509 distinguished name. The -ext value shows what X.509 extensions will be embedded in the certificate. The keytool command also enables users to cache the public keys (in the form of certificates) of their communicating peers. The following are the available options for the -list command: {-providerclass class [-providerarg arg] }: Add security provider by fully qualified class name with an optional configure argument. For example, if you sent your certificate signing request to DigiCert, then you can import their reply by entering the following command: In this example, the returned certificate is named DCmyname.cer. Generating the key pair created a self-signed certificate; however, a certificate is more likely to be trusted by others when it is signed by a CA. Used to identify a cryptographic service provider's name when listed in the security properties file. When both date and time are provided, there is one (and only one) space character between the two parts. When the option isnt provided, the start date is the current time. Otherwise, an error is reported. Using the Java Keytool, run the following command to create the keystore with a self-signed certificate: keytool -genkey \ -alias somealias \ -keystore keystore.p12 \ -storetype PKCS12 \ -keyalg RSA \ -storepass somepass \ -validity 730 \ -keysize 4096 Keystore generation option breakdown: Keytool genkey options for PKCS12 keystore Below example shows the alias names (in bold ). If the keytool command cant recover the private keys or secret keys from the source keystore, then it prompts you for a password. The X.509 standard defines what information can go into a certificate and describes how to write it down (the data format). Share Improve this answer Follow answered Apr 17, 2013 at 14:08 Nickolay Olshevsky 13.5k 1 33 47 The Java keytool is a command-line utility used to manage keystores in different formats containing keys and certificates. The -sigalg value specifies the algorithm that should be used to sign the self-signed certificate. When the -srcalias option is provided, the command imports the single entry identified by the alias to the destination keystore. For example, a distinguished name of cn=myname, ou=mygroup, o=mycompany, c=mycountry). If you prefer, you can use keytool to import certificates. Convert a DER-formatted certificate called local-ca.der to PEM form like this: $ sudo openssl x509 -inform der -outform pem -in local-ca.der -out local-ca.crt. C:> keytool -list -keystore .keystore (If keytool does not run from the directory you are in you will need to fix your Environment variables for JAVA, since Keytool is a JAVA app. Installing SSL Certificate Chain (Root, Intermediate (s), PTA Server certificates): Option values must be enclosed in quotation marks when they contain a blank (space). You can use :c in place of :critical. If -srcstorepass is not provided or is incorrect, then the user is prompted for a password. Entries that cant be imported are skipped and a warning is displayed. Items in italics (option values) represent the actual values that must be supplied. This information is used in numerous ways. There are many public Certification Authorities, such as DigiCert, Comodo, Entrust, and so on. 2. To remove an untrusted CA certificate from the cacerts file, use the -delete option of the keytool command. Step# 2. If you used the jarsigner command to sign a Java Archive (JAR) file, then clients that use the file will want to authenticate your signature. The days argument tells the number of days for which the certificate should be considered valid. Otherwise, an error is reported. This file can then be assigned or installed to a server and used for SSL/TLS connections. To import an existing certificate signed by your own CA into a PKCS12 keystore using OpenSSL you would execute a command like: The -sigalg value specifies the algorithm that should be used to sign the certificate. If the modifier env or file isnt specified, then the password has the value argument, which must contain at least six characters. If such an attack took place, and you didnt check the certificate before you imported it, then you would be trusting anything the attacker signed, for example, a JAR file with malicious class files inside. In many cases, this is a self-signed certificate, which is a certificate from the CA authenticating its own public key, and the last certificate in the chain. If you access a Bing Maps API from a Java application via SSL and you do not . The value of date specifies the number of days (starting at the date specified by -startdate, or the current date when -startdate isnt specified) for which the certificate should be considered valid. Now verify the certificate chain by using the Root CA certificate file while validating the server certificate file by passing the CAfile parameter: $ openssl verify -CAfile ca.pem cert.pem cert . For legacy security providers located on classpath and loaded by reflection, -providerclass should still be used. Copy and paste the Entrust chain certificate including the -----BEGIN----- and -----END----- tags into a text editor such as Notepad. When a port is not specified, the standard HTTPS port 443 is assumed. The KeyStore class provided in the java.security package supplies well-defined interfaces to access and modify the information in a keystore. For keytool and jarsigner, you can specify a keystore type at the command line, with the -storetype option. To generate a CSR, you can use on of the following. For example, most third-party tools require storepass and keypass in a PKCS #12 keystore to be the same. The -list command by default prints the SHA-256 fingerprint of a certificate. The old chain can only be replaced with a valid keypass, and so the password used to protect the private key of the entry is supplied. Certificates are often stored using the printable encoding format defined by the Internet RFC 1421 standard, instead of their binary encoding.
