Constructor Detail

SignatureVerifierImpl

public SignatureVerifierImpl(Signature signature)

The constructor.

Parameters:

signature - the underlying Signature.

Method Detail

verifyAfterUpdate

public boolean verifyAfterUpdate(byte[] signature,
                                 int offset,
                                 int length)

Specified by:

verifyAfterUpdate in interface SignatureVerifierSimple

Parameters:

signature - the byte array with the signature as raw data.

offset - the index where to start reading data from signature.

length - the number of bytes to read from signature.

Returns:

true if the given signature is valid, false otherwise.
