Examples (36) from the manual page, untested
keytool -genkeypair -dname "cn=Mark Jones, ou=Java, o=Oracle, c=US"
First, create a keystore and generate the key pair.-alias business -keypass <new password for private key>-keystore /working/mykeystore-storepass <new password for keystore> -validity 180keytool -genkeypair
The command is significantly shorter when the option defaults are accepted.keytool -certreq -file MarkJ.csr
Generating the key pair created a self-signed certificate.keytool -importcert -alias abc -file ABCCA.cer
If you trust that the certificate is valid, then you can add it to your keystore with the following command:keytool -importcert -trustcacerts -file VSMarkJ.cer
For example, if you sent your certificate signing request to VeriSign, then you can import the reply with the following, which assumes the returned certificate is named VSMarkJ.cer:keytool -exportcert -alias mykey -file MJ.cer
You can export the certificate and supply it to your clients.keytool -importkeystore
For example, to import entries from a typical JKS type keystore key.jks into a PKCS #11 type hardware-based keystore, use the command:-srckeystore key.jks -destkeystore NONE-srcstoretype JKS -deststoretype PKCS11-srcstorepass <src keystore password>-deststorepass <destination keystore pwd>keytool -importkeystore
The importkeystore command can also be used to import a single entry from a source keystore to a destination keystore.-srckeystore key.jks -destkeystore NONE-srcstoretype JKS -deststoretype PKCS11-srcstorepass <src keystore password>-deststorepass <destination keystore pwd>-srcalias myprivatekey -destalias myoldprivatekey-srckeypass <source entry password>-destkeypass <destination entry password>-nopromptkeytool -genkeypair -keystore root.jks -alias root -ext bc:c
The following are keytool commands to generate key pairs and certificates for three entities: Root CA (root), Intermediate CA (ca), and SSL server (server).keytool -genkeypair -keystore ca.jks -alias ca -ext bc:ckeytool -genkeypair -keystore server.jks -alias serverkeytool -keystore root.jks -alias root -exportcert -rfc > root.pemkeytool -storepass <storepass> -keystore ca.jks -certreq -alias ca |keytool -storepass <storepass> -keystore root.jks-gencert -alias root -ext BC=0 -rfc > ca.pemkeytool -keystore ca.jks -importcert -alias ca -file ca.pemkeytool -storepass <storepass> -keystore server.jks -certreq -alias server |keytool -storepass <storepass> -keystore ca.jks -gencert -alias ca-ext ku:c=dig,kE -rfc > server.pemcat root.pem ca.pem server.pem |keytool -keystore server.jks -importcert -alias server
