Method Detail

signBlockSize

public int signBlockSize()

Returns the maximum size in bytes of the fingerprints that can be signed.

signatureSize

public int signatureSize()

Returns the length of a signature in bytes.

verify

public boolean verify(Signature s,
                      Fingerprint fp)
               throws CryptoException

Verify a Signature on a Fingerprint.

In the case of an asymmetric algorithm, this method can only be called on the public key in a pair and verifies signatures generated with the private key in the pair.

In the case of a symmetric algorithm, this method verifies signatures generated with the same key.

Throws:

KeyException - if this is a private key for an asymmetric algorithm
