This is a wild guess, no idea if it's relevant, but the array key32 consists of 33 bytes, 32 containing 0x31 (assuming ASCII) followed by one containing 0x00. Is that how it's meant to be?

(resent, as I never saw this come through the list server) I am looking for some assistance. This should be really easy. But it's not working. Any quick advice I can get would be appreciated. When I use the API, I get a different cypher text then I get from the command line. And the command line appears to be the correct one, as it also matches the cypher text I get when I use the PHP interface. (Once I get the encryption working, I assume the PHP would decrypt it easily, which is my goal) The clear text I am using is simply 6 letters in a file. The file does NOT contain a newline, and neither does the hardcoded buffer used in the C source. The cypher I get is (hex string): from openssl EXE: aed38175d75ea94e7e59833f11400dcf >From C code: 35709aab6f31555a378bc4a6107f3bd0 So, here's the code. Really easy stuff.
