MD5Digest
public MD5Digest()
- Standard constructor
MD5Digest
public MD5Digest(MD5Digest t)
- Copy constructor. This will copy the state of the provided
message digest.
getAlgorithmName
public java.lang.String getAlgorithmName()
- Description copied from interface:
org.bouncycastle.crypto.Digest
- return the algorithm name
getDigestSize
public int getDigestSize()
- Description copied from interface:
org.bouncycastle.crypto.Digest
- return the size, in bytes, of the digest produced by this message digest.
processWord
protected void processWord(byte[] in,
int inOff)
- Specified by:
processWord in class GeneralDigest
processLength
protected void processLength(long bitLength)
- Specified by:
processLength in class GeneralDigest
unpackWord
private void unpackWord(int word,
byte[] out,
int outOff)
doFinal
public int doFinal(byte[] out,
int outOff)
- Description copied from interface:
org.bouncycastle.crypto.Digest
- close the digest, producing the final digest value. The doFinal
call leaves the digest reset.
