Method Detail

newVerifier

public static HMACVerifier newVerifier(String secret)

Return a new instance of the HMAC Verifier with the provided secret.

Parameters:

secret - The secret.

Returns:

a new instance of the HMAC verifier.

canVerify

public boolean canVerify(Algorithm algorithm)

Specified by:

canVerify in interface Verifier

Parameters:

algorithm - The algorithm required to verify the signature on this JWT.

Returns:

True if this Verifier is able to verify a signature using the specified algorithm.

verify
