Enclosing class:

JCAPIMessageDigestDynamic

public static final class JCAPIMessageDigestDynamic.SHA512
extends JCAPIMessageDigestDynamic

The SHA-512 (FIPS 180-2) hashing class.
This algorithm produces a 512-bit (64 bytes) message digest for given input data.

All message digest cryptographic operations are performed by a native MS CAPI CSP, which makes these operations very fast.

An instance of this class must be created by the JCE framework only.

JCAPI provide support for the following algorithm aliases for SHA-512:

• SHA-512
• SHA512
• 2.16.840.1.101.3.4.2.3

This class uses the default MS CAPI CSP (see method JCAPIProperties.getRSACSP()) and the provider type of the default MS CAPI CSP (see method JCAPIProperties.getCachedProviderTypeByCSP(String)).

Here is an example of how to create a SHA-512 based JCAPI message digest instance through the JCE framework:
MessageDigest md = MessageDigest.getInstance("SHA-512", "JCAPI");

To learn more about how this class can be used, please look at the following example programs that can be found in JCAPI's examples directory, by default located in C:\<application data directory>\JCAPI\examples:

• messagedigest\MessageDigestSHA512.java
• cryptofactory\messagedigest\DynamicMessageDigestSHA512.java
