WebIn crittografia, la costruzione di Merkle-Damgård è un metodo per costruire delle funzioni crittografiche di hash resistenti alle collisioni utilizzando delle funzioni a compressione a senso unico . Questa particolare costruzione è stata utilizzata nell'implementazione di molti algoritmi di hash, come ad esempio MD5, SHA1 e SHA2 . WebThe idea of the Merkle-Damgård construction is to split the input x into blocks of size t. The end of the string is filled out with ϑs if necessary. A final block called the "padding block" …
