Re: EVP_* Routines
ok, thanks. I did look at the EVP_EncryptInit man page, but the code I had there, was loosely based on some code I found on the net, they probably had the same problem.

There's an example in the EVP_EncryptInit manual page. It also includes the comment: /* Need binary mode for fopen because encrypted data is * binary data. Also cannot use strlen() on it because * it wont be null terminated and may contain embedded * nulls. */ This is one problem with your code: you are using strncpy and strncat. Steve. -- Dr Stephen N.
