public final class Sha512Capi
extends CapiDigest

An MS-CAPI based implementation of the SHA-512 message digest algorithm.

An instance of this algorithm can be obtained using the Java Cryptography Architecture (JCA), by requesting an 'SHA512CAPI' message digest from the Entrust cryptographic service provider. This can be done using the following call:

MessageDigest.getInstance("SHA512CAPI", "Entrust");

FIPS 140-2:

This class is part of the Toolkit's FIPS 140-2 cryptographic module and contains APIs that are considered part of the logical interface to the Toolkit's FIPS 140-2 cryptographic module; refer to the API documentation for further details

Constructor Detail

Sha512Capi

public Sha512Capi()

The constructor; creates a new instance of the SHA-512 message digest algorithm.

Applications should not use this constructor, instead the message digest algorithm should be requested from the appropriate JCA/JCE cryptographic service provider as follows: MessageDigest.getInstance("SHA512CAPI", "Entrust").

FIPS 140-2:

FIPS Service: Modify Object

This API is part of the logical interface to the Toolkit's FIPS 140-2 cryptographic module; use of this API causes the caller to assume the FIPS 140-2 user role and accesses the following FIPS 140-2 logical interfaces:

• control input interface (API call)
• status output interface (exceptions)
