Discuz Password Generation

Discuz password encryption algorithm is actually two times MD5 encryption, first encrypted with plaintext, then randomly generate a salt, and then add a salt after the first cipher as plaintext and then once again MD5 encryption. The salt is saved in the Uc_members table and can be obtained by user name.

Like this:

MD5 (MD5 (Clear text) +salt)

The following is the implementation code for. NET:

copy code

string getdiscuzpwstring (string sourcestr, string salt) {      return Getmd5hash ( String. Concat (Getmd5hash (SOURCESTR), salt); } String Getmd5hash (String input) {     MD5 md5hasher = MD5. Create ();     byte[] data = Md5hasher.computehash (Encoding.Default.GetBytes (input));     StringBuilder sbuilder = new StringBuilder ();     for (int i = 0; I < data. Length; i++)     {         sbuilder.append (Data[i]. ToString ("X2"));    }     return sbuilder.tostring (); }

Summarize the method of password judgment
1: To install UC
2: Open the database Find uc_members This table, look for the last field "salt", copy the value inside
3:
$s =MD5 (MD5 ("password"). " The value of the Salt field ");
Echo $s;
4: Judging by If
5: Say it again! That's a random 6-digit number!
