SHA1Digest

Class Overview

implementation of SHA-1 as outlined in "Handbook of Applied Cryptography", pages 346 - 349. It is interesting to ponder why the, apart from the extra IV, the other difference here from MD5 is the "endienness" of the word processing!

Summary

[Expand] Inherited Methods
From class org.bouncycastle.crypto.digests.GeneralDigest void finish() int getByteLength() Return the size in bytes of the internal buffer the digest applies it's compression function to. abstract void processBlock() abstract void processLength(long bitLength) abstract void processWord(byte[] in, int inOff) void reset() reset the digest back to it's initial state. void update(byte[] in, int inOff, int len) update the message digest with a block of bytes. void update(byte in) update the message digest with a single byte.
From class java.lang.Object Object clone() boolean equals(Object arg0) void finalize() final Class<?> getClass() int hashCode() final void notify() final void notifyAll() String toString() final void wait() final void wait(long arg0, int arg1) final void wait(long arg0)
From interface org.bouncycastle.crypto.Digest abstract int doFinal(byte[] out, int outOff) close the digest, producing the final digest value. abstract String getAlgorithmName() return the algorithm name abstract int getDigestSize() return the size, in bytes, of the digest produced by this message digest. abstract void reset() reset the digest back to it's initial state. abstract void update(byte[] in, int inOff, int len) update the message digest with a block of bytes. abstract void update(byte in) update the message digest with a single byte.
From interface org.bouncycastle.crypto.ExtendedDigest abstract int getByteLength() Return the size in bytes of the internal buffer the digest applies it's compression function to.
