Reset Joomla 1.5 Password

Sometimes, we forget something. One of them is the password to the backend of our website using Joomla 1.5 engine, where we are located as Super Administrator. We have been updating Joomla models password encryption in the system. If at the previous Joomla or Joomla 1.0, Joomla uses MD5 encryption alone. We can easily replace it, by going to our database using phpmyadmin, then we replace our passwords with MD5 mode plus the password field.

But for now, it can no longer do. Joomla 1.5 is currently using a combination of encryption and encryption encryption MD5 salt. Before we go any further, there is a quick information about encryption and MD5 encryption salt.

 

MD5 Encryption
In cryptography, MD5 (Message-Digest algortihm 5) is a cryptographic hash function widely used to hash 128-bit value. On the Internet standard (RFC 1321), MD5 has been used in a variety of security applications, and MD5 is also commonly used for testing the integrity of a file.
MD5 was designed by Ronald Rivest in 1991 to replace earlier hash function, MD4. In 1996, a disability is found in the design, though not a fatal flaw, a user of cryptography began to advocate using other algorithms, such as SHA-1 (new claim states that the SHA-1 is also disabled). In 2004, disability-more serious defects found to cause the use of the algorithm in order to become more questionable security.

Encryption Salt
In cryptography, a salt which consists of random bits used as one input to a key derivation function. Other input is usually a password. The output of the derived key function is stored as encrypted version of the password. A salt can also be used as part of the key in solving or other cryptographic algorithms. The key derivation function typically uses cryptographic hash function. Sometimes the initiation vector, which previously generated value, will be used as a salt. Some of the data dictionary attack using the pre-salt encryption of dictionary entries: Each bit salt used doubles the amount of storage and computation required.

Now, how do we reset our password in Joomla 1.5? This is the trick to it. First of all go into the cpanel, then go to phpMyAdmin, select our database. Then select the table jos_users. Then select the user that we will edit the password, then enter the following fields in the password field:

50e158580f8cd900d1c319c4c08a8a74:oDzHxt8lPSpvbKYf2vW6Vxp9zsw5SlIZ

Then save. We have edited the password for this is cmsdemo. You should immediately change your password!
We also can change our password using query from phpMyAdmin:


Hopefully useful.
