Discuz Forum Password and secret encryption rules

Discuz Password Encryption rules:

MD5 (MD5 (' string '). ' Fixed word string ');

Fixed strings are randomly generated at the time of registering the user, and are saved in the Salt field of the data table pre_ucenter_members.

For example: If the password is 123456789 and the fixed string is jb51, then the encryption rule is: MD5 (MD5 (' 123456789 '). Jb51 '); The result is: 96122FF0DD306C912AAB15ADCCF21DF1
