Member Function Documentation

virtual void P::Digest::clear (   )  [pure virtual]

Clear the digest. Reinitializes the digest object. Wipes out current object state and reinitializes it with the magic values. After that you can calculate another digest using update(). Implemented in P::MD4Digest, P::MD5Digest, and P::SHA1Digest.

virtual std::string P::Digest::digest (   )  const [pure virtual]

Get the current digest. Retrieves the current digest sum as a string. The method does not wipe out the current object state, if you want to re-use the object to calculate another sum call clear(). Returns: A string containing the current digest Implemented in P::MD4Digest, P::MD5Digest, and P::SHA1Digest.

Digest& P::Digest::operator<< (  const std::string &  str  )

Update digest sum.

virtual void P::Digest::update (  const char *  buff, size_t  len )  [pure virtual]

Update digest sum. Updates the digest. The method may be called many times before the digest string is being retrieved with digest(). Parameters: buff  The input buffer len  Size of the input buffer Implemented in P::MD4Digest, P::MD5Digest, and P::SHA1Digest.
