Обсуждение: encryption for postgres
I need to save user ids and passwords to be used for access to records in a database. The passwords should be encrypted before saving. Are there builtin or standard php functions to do encryption/decryption or does one need to add a library to a standard php install (RedHat 7.1).

There are such functions for both PHP and PostgreSQL -- check out pgcrypto in the contrib directory of the tarball for PostgreSQL support and the mcrypt functions for PHP support... Both link to external libraries.. Note that MD5 and DES encryption might be available without linking to external libs but those are one-way encryptions.... -Mitch ----- Original Message ----- From: <hodges@xprt.net> To: <pgsql-php@postgresql.org> Sent: Sunday, October 14, 2001 6:50 PM Subject: [PHP] encryption for postgres > I need to save user ids and passwords to be used for access > to records in a database.

Hi Tom, There is a standard function - 'crypt( )' . I'm afraid I can't give you a detailed run down on how to use it off the top of my head, but the manual covers it pretty well, and you can also check it out at http://www.php.net If you need more serious security there are other encryption functions around, but I think you have to load most of these in as separate modules. I seem to remember that php builder have done a couple of good articles on such things (don't quote me on that though).

Thanks for all the advice on encryption. I am just looking for one way encryption so I will use crypt with either md5 or blowfish, depending on which is available. Cheers, Tom
