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. WebOne basic requirement of any cryptographic hash function is that it should be computationally infeasible to find two distinct messages that hash to the same value. MD5 fails this requirement catastrophically; such collisions can be found in seconds on an ordinary home computer.

WebHMAC. In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. As with any MAC, it may be used to simultaneously verify both the data … WebHash Functions; Secret Key Cryptography, or symmetric cryptography, uses a single key to encrypt data. Both encryption and decryption in symmetric cryptography use the same key, making this the easiest form of cryptography.
