Field Detail

SHA1

public static final HMACAlgorithm SHA1

SHA-1 HMAC. This is a Message Authentication Code that uses a symmetric key together with SHA-1 digesting to create a form of signature.

Method Detail

fromOID

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

Looks up the HMAC algorithm with the given OID.

Throws:

java.security.NoSuchAlgorithmException - If no registered HMAC algorithm has the given OID.
