(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
From C code: 35709aab6f31555a378bc4a6107f3bd0
So, here's the code. Really easy stuff. The Key and IV are the same,
--- Command line ----
openssl
enc -aes-256-cbc
-in infile.txt -K 3131313131313131313131313131313131313131313131313131313131313131
-iv fbd070327199c9df7760c5a113bed7a3
-nosalt -out cypher.bin
---- C code:
static unsigned char initVect[] = {
0xfb,0xd0,0x70,0x32,0x71,0x99,0xc9,0xdf,
0x77,0x60,0xc5,0xa1,0x13,0xbe,0xd7,0xa3
};
static const unsigned char key32[] =
{"11111111111111111111111111111111"};
void AES256Encrypt(unsigned char *dst, const char *src, int len) {
AES_KEY aeskey;
unsigned char iv[sizeof(initVect)]; /* Our own personal copy of the initialization */
memcpy(iv,initVect,sizeof(initVect)); /* vector, to handle the fact that it's not CONST */
AES_set_encrypt_key(key32, 256, &aeskey);
AES_cbc_encrypt((unsigned char *)src, (unsigned char *) dst, len, &aeskey, iv, AES_ENCRYPT);
}
Any help is appreciated!
