i used crypto once and it didnt work on some ppl's machines.... i would suggest not using it.... use rc4.. i have a rc4 class module if u want it... its real nice.

Which one? I see 15 APIs that start with Crypt in the APIViewer.

First off - here is sample Crypto code -

Hack - you have to call these in sequence - same ideas as FindFirstFile...FindCLose

AlbafaN - you're right - these only work on newer OS versions with more recent verison of Internet Explorer. I believe they are part of support for IE5.0 SSL FOr wide disrtibution find something else.

I suggest going out and looking for a decent crypto library or control.

Preferably one that can hash and encrypt with a known, strong routine like DES

For most non sensative apps, I have a little .dll I found that hashes / unhashes base64 and crypts / decrypts DES-56

Of course, such programs with static, compiled keys are broke in 15 seconds with a dissassembler. If you're really serious, you have a lot of work and research to do on strong encryption.
