Method Detail

verifyAfterUpdate

default boolean verifyAfterUpdate(byte[] signature)

Parameters:

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

Returns:

true if the given signature is valid, false otherwise.

verifyAfterUpdate

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

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.

verify

default boolean verify(byte[] input,
                       byte[] signature)

Parameters:

input - the message data for which the signature was created.

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

Returns:

true if the given signature is valid, false otherwise.

verify

default boolean verify(byte[] input,
                       byte[] signature,
                       int signatureOffset,
                       int signatureLength)

Parameters:

input - the message data for which the signature was created.

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

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

signatureLength - the number of bytes to read from signature.

Returns:

true if the given signature is valid, false otherwise.

verify

default boolean verify(byte[] input,
                       int inputOffset,
                       int inputLength,
                       byte[] signature,
                       int signatureOffset,
                       int signatureLength)

Parameters:

input - the message data for which the signature was created.

inputOffset - the index where to start reading data from input.

inputLength - the number of bytes to read from input.

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

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

signatureLength - the number of bytes to read from signature.

Returns:

true if the given signature is valid, false otherwise.
