Constructor Detail

SHA1HashBuffer

public SHA1HashBuffer()

Constructs a new SHA1HashBuffer.

Method Detail

add

public void add(byte input)

Adds the specified byte to the digest.

Specified by:

add in interface OutputBuffer

Specified by:

add in class OutputBufferImpl

add

public void add(byte[] input,
                int offset,
                int length)

Adds length bytes of the specified array to the digest, starting at offset.

Specified by:

add in interface OutputBuffer

Specified by:

add in class OutputBufferImpl

toHash

public SecureHash toHash()

Computes and returns the digest of all inputs. Also resets internal state, so do not attempt to produce intermediate hashes by calling this method prematurely.

This implementation always returns a SHA1Hash.

Specified by:

toHash in class SecureHashBuffer

main

public static void main(String[] args)
