Method Detail

getChunkSize

protected int getChunkSize()

Description copied from class: Digest

The processing chunk size, used in HMAC/PRF implementations.

Overrides:

getChunkSize in class Digest

Returns:

block size in bytes

getUnderlyingDigest

protected org.bouncycastle.crypto.Digest getUnderlyingDigest()

_update

protected void _update(byte[] data,
                       int offset,
                       int size)

Description copied from class: Digest

Override to process sequence of bytes. Is called only if the #_digest() was not called. Inner logic protects from update after digest is calculated.

Specified by:

_update in class Digest

Parameters:

data - source message

offset - index to start processing from

size - number of bytes to proces

_digest

protected byte[] _digest()

Description copied from class: Digest

Override it to calculate and return digest of all processed data. It is called only once per instance.

Specified by:

_digest in class Digest

Returns:

digest

getLength

public int getLength()

Description copied from class: Digest

Override to provide digest length in bytes.

Specified by:

getLength in class Digest
