Field Detail

AES

public static final CMACAlgorithm AES

CMAC AES-X. This is a Message Authentication Code that uses a symmetric key together with the AES cipher to create a form of signature. Note that we pass null for the OID here: neither NIST nor any other standards body has defined an OID for use with CMAC. Since we use a PKCS#11 backend and NSS doesn't otherwise define CMAC based on a SEC OID, we don't strictly need one. We've left the fromOID code (and oid parameter in the constructor) as other projects use them for HMACAlgorith. At such time as an OID is defined, it can be added here.

public static final CMACAlgorithm AES128

AES192

Method Detail

fromOID

public static CMACAlgorithm fromOID(OBJECT_IDENTIFIER oid)
                             throws java.security.NoSuchAlgorithmException
