Constructor Detail

BcMTCSignatureVerifier

public BcMTCSignatureVerifier(java.lang.String algorithm,
                              org.bouncycastle.crypto.params.AsymmetricKeyParameter publicKey)

Method Detail

getAlgorithm

public java.lang.String getAlgorithm()

Specified by:

getAlgorithm in interface MTCSignatureVerifier

Returns:

the MTC signature algorithm this verifier is bound to — one of the MTCSignatureAlgorithm constants. Lets callers check a registered verifier against the algorithm a CA publishes for its cosigner (Section 5.5 sigAlg).

verify

public boolean verify(byte[] cosignedMessage,
                      byte[] signature)

Specified by:

verify in interface MTCSignatureVerifier

Parameters:

cosignedMessage - the encoded CosignedMessage bytes

signature - the candidate signature

Returns:

true if the signature is valid for the bound public key and algorithm
