This problem has been resolved.
int EVP_EncryptInit_ex(EVP_CIPHER_CTX *ctx, const EVP_CIPHER *type,
ENGINE *impl, unsigned char *key, unsigned char *iv);
EVP_EncryptInit_ex(&ctx, EVP_bf_cbc(), NULL, key, iv);
In the example at
http://www.openssl.org/docs/crypto/EVP_EncryptInit.html#EXAMPLES the
function is called with incorrect parameters. Parameter two needs to be
a const EVP_CIPHER *type and parameter three should be type ENGINE
*impl. The EVP_EncryptInit_ex() function in the example should be as
follows: EVP_EncryptInit_ex(&ctx, NULL, EVP_bf_cbc(), key, iv);
int do_crypt(char *outfile)
{
unsigned char outbuf[1024];
int outlen, tmplen;
unsigned char key[] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15};
unsigned char iv[] = {1,2,3,4,5,6,7,8};
char intext[] = "Some Crypto Text";
EVP_CIPHER_CTX ctx;
FILE *out;
EVP_CIPHER_CTX_init(&ctx);
EVP_EncryptInit_ex(&ctx, NULL, EVP_bf_cbc(), key, iv);
if(!EVP_EncryptUpdate(&ctx, outbuf, &outlen, intext, strlen
(intext)))
{
return 0;
}
if(!EVP_EncryptFinal_ex(&ctx, outbuf + outlen, &tmplen))
{
return 0;
}
outlen += tmplen;
EVP_CIPHER_CTX_cleanup(&ctx);
out = fopen(outfile, "wb");
fwrite(outbuf, 1, outlen, out);
fclose(out);
return 1;
}
