[RESOLVED] Conversion Problem

[couttsj]

Reply to Bonnie:

If I change my original code to an empty byte string (32 VbNull) instead of the actual random bytes, it does not error out. I suspect that is why your original code worked. Experimenting a little, if I try to change the MAC Key Hash protocol to CALG_SHA1 instead of CALG_MD5 using KP_SCHANNEL_ALG as the parameter, it now errors out. It almost seems that any change from the default settings causes an error. I seem to remember somewhere that before using SCHANNEL you are supposed to enumerate the protocols. It never said why, but I will give that a try and let you know.

Edit:
After acquiring the context for RSA SCHANNEL, enumerating algorythms shows:

Unfortunately, the error still remains.
