RC4 is pretty good, a good implementation uses a dynamic key. the only problem (but, also a benefit) is that it is symmetric. you use the same key to decrypt and encrypt. but, if thats not sufficient, you should look at a public/private key system :) and, that stuff is very computational intensive. OS5 CPM libaries have routines to verify RSA signing, but nothing there for doing encryption/decryption yet. --- Aaron Ardiri PalmOS Certified Developer [EMAIL PROTECTED] http://www.mobilewizardry.com/members/aaron_ardiri.php -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
