Method Detail

getAlgorithmIdentifier

org.spongycastle.asn1.x509.AlgorithmIdentifier getAlgorithmIdentifier()

Return the algorithm identifier describing the signature algorithm and parameters this expander supports.

Returns:

algorithm oid and parameters.

getOutputStream

java.io.OutputStream getOutputStream()

Returns a stream that will accept data for the purpose of calculating a signature for later verification. Use org.spongycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.

Returns:

an OutputStream

verify

boolean verify(byte[] expected)

Parameters:

expected - expected value of the signature on the data.

Returns:

true if the signature verifies, false otherwise
