Examples of java.security.KeyPairGenerator.generateKeyPair()

java.security.KeyPairGenerator.generateKeyPair()
Generates a key pair.
If this KeyPairGenerator has not been initialized explicitly, provider-specific defaults will be used for the size and other (algorithm-specific) values of the generated keys.
This will generate a new key pair every time it is called.
This method is functionally equivalent to {@link #genKeyPair() genKeyPair}. @return the generated key pair
