Method Detail

forSigning

public static EdDSASigningHandler forSigning(byte[] privateKey)

Initialises a signing handler for signing.

Parameters:

privateKey - the private key bytes.

Returns:

the signing handler.

forVerification

public static EdDSASigningHandler forVerification(byte[] publicKey)

Initialises a signing handler for verification.

Parameters:

publicKey - the public key bytes.

Returns:

the signing handler.

sign

public byte[] sign(JwsAlgorithm algorithm,
                   byte[] data)

Description copied from interface: SigningHandler

Signs the given raw data bytes using the Java Cryptographic algorithm defined by the JwsAlgorithm.

Specified by:

sign in interface SigningHandler

Parameters:

algorithm - the JWS signature algorithm to use.

data - the raw data to sign.

Returns:

the signature.

verify

public boolean verify(JwsAlgorithm algorithm,
                      byte[] data,
                      byte[] signature)

Description copied from interface: SigningHandler

Verifies that the given signature is valid for the given data.

Uses the Java Cryptographic algorithm defined by the JwsAlgorithm and private key to create a new signature of the data to compare against the given signature to see if they are identical.

Specified by:

verify in interface SigningHandler

Parameters:

algorithm - The JwsAlgorithm defining the JavaCryptographic algorithm.

data - The data that was signed.

signature - The signature of the data.

Returns:

true if the signature is a valid signature of the data.
