Hi there, I am developing an encryption program on vb 6 which will then be de-crypted by CodeIgniter.
My encryption program uses pbkdf2 whereas CodeIgnitor is using hkdf.. Can that be changed?
Also, my program does not generate an HMAC-key. Is it necessary?[ I am not even a php developer but as far as I could research/understand I think we can put it off by setting hmac to false]. Urgent reply please. Thanks.
