The benefit of hashing is that the application never needs to store the clear text password. If the two hashes are an exact match, the user provided a valid username and password. Other considerations Hashing algorithm selection Encryption algorithm selection Per User Salt Protection of key Computational difficulty How does the application authenticate a user with a password hash? When the application receives a username and password from a user, it performs the hashing operation on the password and compares the resulting hashed value with the password hash stored in the database for the particular user. Send instant message and offline message. Table 1: Differences Between Hashing and Symmetric Encryption Hashing Symmetric Encryption One-way function Reversible Operation Invertible Operation? No, Yes, For modern hashing algorithms it is not easy to reverse the hash value to obtain the original input value Symmetric encryption is designed to allow anyone with access to the encryption key to decrypt and obtain the original input value.See note below on rainbow tables, salts, etc. BigAnt Office Messenger Free version v.2.82 BigAnt Messenger Free is specially designed for secure and efficient office communication. Anyone possessing the key can decrypt an encrypted value to obtain the original value. This is very unique code decrypter tool which helps to decrypt data with different encryption algorithms.
