Hi Dan

Which crypto.fll are you using? I was checking out Cipher50.fll orignally produced by Tom Rettig.

>>I am using the crypto control from VFP's foundation classes but it is becoming a real pain as the decryption fails on some machines. The last instance happened on a Win2000 laptop. I made sure that I specified that the encryption should be based on MS Base Cryptographic Provider so that it did not accidently use the new enhanced version. However it still fails occasionally on some machines.
