Method Details

verifySignature

public void verifySignature(byte[] signature,
 byte[] signatureBase,
 PublicKey publicKey,
 int signatureAlgorithm)

isSupported

public boolean isSupported(int signatureAlgorithm)

Whether the configured crypto provider can verify signatures for the given COSE algorithm code point. This asks the provider rather than a list, so the FIPS build reports its own, narrower capability instead of inheriting the standard build's answer.

getSignatureChecker

public Signature getSignatureChecker(int signatureAlgorithm)

getDigest

public MessageDigest getDigest(int signatureAlgorithm)

verifySignature

public void verifySignature(byte[] signature,
 byte[] signatureBase,
 Certificate certificate,
 int signatureAlgorithm)
