passwords

I'm having MySQL on RHEL, and phpMyAdmin interface also. I have normal MySQL user access which i remember but i forget the root password. How to SAFELY reset the MySQL root password? (I have root account on O/S) From Here: http://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html Stop mysqld and restart it with the --skip-grant-tables option. This enables anyone to connect without a password and with all privileges. Because this is insecure, you might want to use --skip-grant-tables in conjunction with --skip-networking to prevent remote clients from connecting. Connect to the mysqld

I have a bit of a dilemma here. I have a drupal 7 database table of users, with corresponding passwords. All these passwords have been naturally encrypted. My assumption is that these are MD5 hashes, but not quite. The challenge here is that, we are utilizing the same set of users in a companion website that uses similar credentials but a different technology [please don't blame me for this, I a mere pawn]. Now if I knew how Drupal goes about encrypting its passwords, maybe I could decrypt them and apply the same in my backend logic? Note that these passwords are hashed , not encrypted. The

Can anyone, please, explain to me how to transform a phrase like "I want to buy some milk" into MD5? I read Wikipedia article on MD5, but the explanation given there is beyond my comprehension: "MD5 processes a variable-length message into a fixed-length output of 128 bits. The input message is broken up into chunks of 512-bit blocks (sixteen 32-bit little endian integers)" "sixteen 32-bit little endian integers" is already hard for me. I checked the Wiki article on little endians and didn't understand a bit. However, the examples of some phrases and their MD5 hashes in that Wiki article are

I have a problem, because I have a database with users and theirs passwords were secured with Django (pbkdf2). So '123' looks like this: pbkdf2_sha256$20000$MflWfLXbejfO$tNrjk42YE9ZXkg7IvXY5fikbC+H52Ipd2mf7m0azttk= Now I need to use this passwords in PHP project and I don't have any idea how to compare them. pbkdf2_sha256$20000$MflWfLXbejfO$tNrjk42YE9ZXkg7IvXY5fikbC+H52Ipd2mf7m0azttk= Let's break this down. The $ are separators: pbkdf2_sh256 means PBKDF2-SHA256, i.e. hash_pbkf2('sha256', ...) 20000 is the iteration count MflWfLXbejfO is the salt tNrjk42YE9ZXkg7IvXY5fikbC+H52Ipd2mf7m0azttk= is

For security purposes I will encrypt some data, including the user password in my application. My colleagues have chosen scrypt hashing algorithm, for a 64 bytes length, with a fixed seed, then converted to hex. Hashing " A12345678Z " leads to: 25fac84a1cc3a8f6706848d1016cfe7e9d3631691306dcacae68c11c7b54f0bf89e7a7fc51f7fcc19671775acb21c8d928c4c96bb66d915925de58b8b36ab251 Seed is “ HeanpyftAkWilfUd ”.
