oHash Function: It is a Message Digest algorithm which coverts any length of a message into a unique set of bits. It is widely used MD5 (Message Digest) and SHA-1 (Secure Hash Algorithm) algorithms. SHA1 is more resistant to brute-force attacks than MD5, however it is slower. SHA1 is more resistant to brute-force attacks than MD5, however it is slower

￿MD5: A one-way hashing algorithm that produces a 128−bit hash.

￿SHA1: A one-way hashing algorithm that produces a 160−bit hash
