RIPEMD-160_ produces the 160 bit digest of a message. >>> from Crypto.Hash import RIPEMD >>> >>> h = RIPEMD.new() >>> h.update(b'Hello') >>> print h.hexdigest() RIPEMD-160 stands for RACE Integrity Primitives Evaluation Message Digest with a 160 bit digest. It was invented by Dobbertin, Bosselaers, and Preneel. This algorithm is considered secure, although it has not been scrutinized as extensively as SHA-1. Moreover, it provides an informal security level of just 80bits. .. _RIPEMD-160: http://homes.esat.kuleuven.be/~bosselae/ripemd160.html z$Id$)ÚnewÚ digest_sizeÚ RIPEMD160Hashé)Ú*)ÚHashAlgoNc@s4eZdZdZedƒZdZdZd dd„Zd dd „Z dS) rzNClass that implements a RIPMD-160 hash :undocumented: block_size z+$éé@NcCst |t|¡dS©N)rÚ__init__Ú hashFactory©ÚselfÚdata©rúD/var/www/html/env/lib/python3.10/site-packages/Crypto/Hash/RIPEMD.pyr FszRIPEMD160Hash.__init__cCst|ƒSr )rr rrrrIszRIPEMD160Hash.newr ) Ú__name__Ú __module__Ú __qualname__Ú__doc__ÚbÚoidrÚ block_sizer rrrrrr3s  rcCs tƒ |¡S)aReturn a fresh instance of the hash object. :Parameters: data : byte string The very first chunk of the message to hash.
