Method Detail

verifyAfterUpdate

default boolean verifyAfterUpdate(S signature)

Parameters:

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,
                       int offset,
                       int length,
                       S signature)

Parameters:

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

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

length - the number of bytes to read from input.

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,
                       S 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.

verifyUnsafe

default boolean verifyUnsafe(byte[] input,
                             SignatureBinary 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(CryptoBinary input,
                       S signature)

Parameters:

input - the message data for which the signature was created. E.g. a Hash.

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

Returns:

true if the given signature is valid, false otherwise.
