I am trying to port some python code to C and the python code uses some encryption algorithms so I want to use openssl's algorithms.
python code: hmac_md5 = HMAC.new(nlkm,ch) rc4key = hmac_md5.digest() rc4 = ARC4.new(rc4key) data = rc4.encrypt(edata) c code: HMAC_CTX hmac; RC4_KEY rc4; unsigned char nlkm[64]; unsigned char ch[16]; unsigned char *encrypteddata=NULL; unsigned char md[16]; unsigned int md_len=0; HMAC_CTX_init(&hmac); (void) HMAC(EVP_md5(), nlkm, 64, ch, 16, md, &md_len); HMAC_CTX_cleanup(&hmac); RC4_set_key(&rc4, 16, md); RC4(&rc4, (unsigned long)sizeofedata, encrypteddata, encrypteddata); When I print the value for rc4key in the python code everything is right. When I print md which should be the same value in C, I get something different. Everything up to the encryption point is the same for the C and python code. Did I use the openssl functions correctly? Do the 4 C lines corresponded to the 4 python lines?
