tarun Posted February 24, 2007 Share Posted February 24, 2007 I Need To Make An Encryption System I've Had An Idea Using str_replace Which Is Pretty Basic Just Replace Characters With Different Charchters Eg. a --> y b --> h ETC... Any Ideas On A More Advanced System Thnx, Tarun Link to comment https://forums.phpfreaks.com/topic/39963-my-own-encryption-system/ Share on other sites More sharing options...
utexas_pjm Posted February 24, 2007 Share Posted February 24, 2007 A 1 to 1 mapping like that is in a practical sense, not encrypted. If you're looking for a relatively secure encryption algorthm have a look here: http://php.net/mcrypt. If you're just trying to learn the theory I'd google "2 way encryption algorithms".

superuser2 Posted February 25, 2007 Share Posted February 25, 2007 Mcrypt is the way to go, it's the only way in PHP to get an actually 'ecrypted' text and be able to be decrypted. 1 to 1 character renaming is extremely basic, easy to spot, and can be cracked easily by anyone who knows the first thing about cryptography. It maybe, just maybe, might keep a 7-year-old out, but even then, it's very, very easy to spot and decrypt.

BrandonE97 Posted February 26, 2007 Share Posted February 26, 2007 I was looking at the different encryption algorithms and was wondering which is the best and most secure to use?
