public final class SHA1Digest
extends AbstractDigest
implements Digest

The SHA1Digest class implements the SHA-1 algorithm.

We implemented SHA1 as it's defined in FIPS 180-1.

update

public void update(byte[] data,
                   int offset,
                   int length)
Description copied from interface: Digest
Passes a byte array of data, specified by the length and offset, into the hash algorithm.

Specified by:
update in interface Digest
Overrides:
update in class AbstractDigest

public int getDigest(byte[] buffer,
                     int offset,
                     boolean resetDigest)
Description copied from interface: Digest
Inserts the digest of all the input data since the last reset into the specified buffer at the given offset.

Specified by:
