I've never used PGP before<br /> This way would not be saving the CCs into a DB<br /> How would I send to PGP? I've been rooting around PHP.net and <strong>shell_exec()</strong> seems to work<br /> Would this way be more secure?</p> Wed, 01 Jan 2003 16:28:13 +0000 nike_guy_man comment 1122503 at https://www.webmaster-forums.net https://www.webmaster-forums.net/server-side-scripting/best-encryption#comment-1122501 <p>hehe, you could do all kinds of stuff to them. You could bit shift stuff, then run mcrypt.</p> <p>Something to think about: anyone who has read access to the file making the encrypted string, will be able to decrypt it. Who has read access to the files?</p> <p>On some hosts, I've been able to traverse the whole file system, and read nearly anything I want. Even files in another user's account. NOT GOOD! chmod 600</p> Wed, 01 Jan 2003 14:02:26 +0000 Mark Hensler comment 1122501 at https://www.webmaster-forums.net https://www.webmaster-forums.net/server-side-scripting/best-encryption#comment-1122488 <p>i'd suggest compiling php with mcrypt. nothing is foolproof, especially two-way encryption, but it's pretty decent considering what's available (nothing).</p> <p>There are other encryption algorithms available converted to php, though. May even be more secure to use some obscure algorithm to encode the data.</p> Wed, 01 Jan 2003 06:27:23 +0000 ROB comment 1122488 at https://www.webmaster-forums.net
