Change Password for Java KeyStore File

See more Java KeyStore (JKS) Examples

Demonstrates how to load a Java keystore, change the password, and save using the new password. If the Java keystore contains only trusted root certificates, then it's simply a matter of loading the JKS with the existing password, and then saving with a new password. If the JKS contains private key entries, then each private key entry must be re-keyed using the new password by calling the ChangePassword method. PowerBuilder
