I think this script should now be functional enough to post here at ActiveState. When you reply or vote down, please post some information on your problem with the code, and if you can, maybe something about the solution. This interface works, and is designed especially for Python. If you like it, don't be afraid to post that either, constructive criticism is all good, but compliments are even better! ;)

2012-07-10T19:52:17-07:00

PHP recipe 576894 by Xavier L. (crypt, generation, generator, hash, pass, password, salt, secure, security, string). Revision 6.

This function will generate a salt for use with passwords ranging using characters in range a to z, A to Z, 0 to 9 and !@#$%&?. The characters are sorted in a random value and can appear more than one time in the string. This way, this function is more powerful than the *shuffle() function. This means that the salt could also be longer than the character list.
