>The compact framework does not contain (hardly) any crypto stuff (System.Security.Cryptography). I have been using a class I wrote to encrypt and decrypt text (which used a lot of stuff from System.Security.Cryptography). Now I need to share my encrypting and decrypting with a PPC application and since a lot of this is not available in the compact framework I either have to write my own or use someone elses.

All the encryption mechanism I use are based on System.Security.Cryptography. It is a surprise to here that this is not included in the compact version. Keep us inform on the evolution.
