————————————————-
Notes:

[1] Since the hashing requires not only a password but also a salt (or a user name), which is unique for each user, the attack speed for such hashes will decline proportionally to their count (for example, attacking 100 hashes will go 100 times slower than attacking one hash).

[2] The hash is to be loaded to the program in full, to the “Hash” column – the program will automatically extract the salt and other required data from it.

[3] The ‘:’ character can be used as salt; however, since it is used by default for separating hash and salt in PasswordsPro, it is recommended that you use a different character for separating fields; e.g., space.

[4] Salt can contain special characters – single or double quotes, as well as backslash, which are preceded (after obtaining dumps from MySQL databases) by an additional backslash, which is to be removed manually. For example, the salt to be loaded to the program would be a’4 instead of a\’4, as well as the salts a”4 instead of a\”4 and a\4 instead of a\\4.
