Parameters:

signingKey - the private key to use for signing. Must not be null.

ECDSASigningHandler

public ECDSASigningHandler(ECPublicKey verificationKey)

Constructs the ECDSA signing handler for verification only.

Parameters:

verificationKey - the public key to use for verification. Must not be null.

Method Details

sign

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

Description copied from interface: SigningHandler

Signs the given String data using the Java Cryptographic algorithm defined by the JwsAlgorithm. The signature is created using the given private key.

Specified by:

sign in interface SigningHandler

Parameters:

algorithm - The JwsAlgorithm defining the Java Cryptographic algorithm.

data - The data to be signed.

Returns:

A byte array of the signature.

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.
