WebAn example This example uses the common unix utility "md5sum", which hashes the data on stdin to a 128 bit hash, displayed as 32 hex digits. Assume the password is "mysecretpass" and both the client and the server know this.The client connects to the server. The server makes up some random data, say "sldkfjdslfkjweifj ”.The server sends this data to client. WebTypes of security of hash functions [ edit] Generally, the basic security of cryptographic hash functions can be seen from different angles: pre-image resistance, second pre-image resistance, collision resistance, and pseudo-randomness. Pre-image resistance: given a hash. h {\displaystyle h} it should be hard to find any message.
