Class AlgorithmID.MessageDigestAlgs

java.lang.Object

com.entrust.toolkit.asn1.structures.AlgorithmID.MessageDigestAlgs

Enclosing class:

AlgorithmID

public static final class AlgorithmID.MessageDigestAlgs
extends java.lang.Object

Contains a set of pre-defined (known) message digest algorithm identifiers.

These algorithm identifiers are all constant, and not modifiable. To obtain a modifiable instance call Object.clone(). If an attempt is made to modify a constant algorithm identifier, an exception will be thrown.

Since:

7.0

Method Detail

getDigestLength

public static int getDigestLength(AlgorithmID digestAlgId)
                           throws java.security.NoSuchAlgorithmException

Returns the digest length (in bytes) of the indicated digest algorithm.

This API can only provide the digest length for known digest algorithms. All known digest algorithms are defined as static members of this class.

Parameters:

digestAlgId - an algorithm identifier for a digest algorithm

Returns:

the digest length (in bytes) of the indicated digest algorithm

Throws:

java.security.NoSuchAlgorithmException - if the algorithm identifier does not correspond to a known digest algorithm

Since:
