Method Detail

verify

public static boolean verify(byte[] a_message,
                             byte[] a_signature,
                             AsymmetricCryptoKeyPair a_keyPair)

Verifies the signature for a message.

Parameters:

a_message - a message

a_signature - the signature to verify

a_keyPair - a key pair for verification of the signature

Returns:

true if the signature is valid; false otherwise

verify

public static boolean verify(byte[] a_message,
                             byte[] a_signature,

Verifies the signature for a message.

Parameters:

a_message - a message

a_signature - the signature to verify

a_publicKey - a public key for verification of the signature

Returns:

true if the signature is valid; false otherwise

sign

public static byte[] sign(byte[] a_message,
                          AsymmetricCryptoKeyPair a_keyPair)
