Méthodes protégées

Méthode	Description
EngineDigest ( ) : byte[]	Completes the hash computation by performing final operations such as padding. Completes the hash computation by performing final operations such as padding. At the return of this engineDigest, the MD engine is reset.
EngineReset ( ) : void	Resets this object disregarding any temporary data present at the time of the invocation of this call. Resets this object disregarding any temporary data present at the time of the invocation of this call.
EngineUpdate ( byte b ) : void	Continues an MD4 message digest using the input byte. Continues an MD4 message digest using the input byte.
EngineUpdate ( byte input, int offset, int len ) : void	MD4 block update operation. MD4 block update operation. Continues an MD4 message digest operation, by filling the buffer, transform(ing) data in 512-bit message block(s), updating the variables context and count, and leaving (buffering) the remaining bytes in buffer for the next update or finish.
