Hello. I'm looking at the various CRYPT / one-way encryption commands and i was wondering if there is a way to create a crypt but restrict output to alpha-numeric (a to z, A to Z and 0-9) without the special characters ? Basically ive got a starting reference - numeric over 10,000,000 and other numbers and want to do a crypt (or something) but exclude special characters from the crypt result. The best I can think of is to do a crypt (or whatever) etc and then do a preg_replace to remove the special characters etc.. The result will be shorter (length), but will be an alpha-numeric crypt. -- Gordon.
