Method Details

isSigningAlgorithm

public static boolean isSigningAlgorithm(int publicKeyAlgorithm)

Return true, if the public key algorithm that corresponds to the given ID is capable of signing.

Parameters:

publicKeyAlgorithm - public key algorithm id

Returns:

true if algorithm can sign

isEncryptionAlgorithm

public static boolean isEncryptionAlgorithm(int publicKeyAlgorithm)

Return true, if the public key algorithm that corresponds to the given ID is capable of encryption.

Parameters:

publicKeyAlgorithm - public key algorithm id

Returns:

true if algorithm can encrypt

isX25519Key

public static boolean isX25519Key(PublicKeyPacket publicKeyPacket)

Return true, if the passed in PublicKeyPacket is based on X25519, either the legacy variant via PublicKeyAlgorithmTags.ECDH over curve25519, or the modern PublicKeyAlgorithmTags.X25519.

Parameters:

publicKeyPacket - public key packet

Returns:

true if the key is an X25519 key
