To accommodate longer password hashes, the Password column in the user table was changed at this point to be 41 bytes, its current length. The longer password hash format has better cryptographic properties, and client authentication based on long hashes is more secure than that based on the older short hashes. In MySQL 4.1.1, the hashing method was modified to produce a longer 41-byte hash value:.This method was short lived and the following discussion says nothing more about it.
The changes in MySQL 4.1 took place in two stages: There were several aspects to this change: Decryption is the process of encrypted data into its original form. MySQL 4.1 introduced password hashing that provided better security and reduced the risk of passwords being intercepted. Encryption is the process of encoding a message or information.
