类 SM3Digest

java.lang.Object

org.bouncycastle.crypto.digests.GeneralDigest

com.seeyon.ctp.common.security.SM3Digest

所有已实现的接口:

org.bouncycastle.crypto.Digest, org.bouncycastle.crypto.ExtendedDigest, org.bouncycastle.util.Memoable

public class SM3Digest
extends org.bouncycastle.crypto.digests.GeneralDigest

Implementation of Chinese SM3 digest as described at http://tools.ietf.org/html/draft-shen-sm3-hash-01 and at .... ( Chinese PDF )

The specification says "process a bit stream", but this is written to process bytes in blocks of 4, meaning this will process 32-bit word groups. But so do also most other digest specifications, including the SHA-256 which was a origin for this specification.
