I hope I am writing to the right place. Example for "General encryption and decryption function example using FILE I/O and AES128 with a 128-bit key" has two errors. I spent a lot of time trying to figure out what I did wrong for a while... 1. ctx is already a pointer; it does not need to be indirected to get the pointer. EVP_CipherInit_ex(&ctx, EVP_aes_128_cbc(), NULL, NULL, NULL, do_encrypt); should say: EVP_CipherInit_ex(ctx, EVP_aes_128_cbc(), NULL, NULL, NULL, do_encrypt); 2. ciphertext length is not used to update write position: if(!EVP_CipherUpdate(ctx, outbuf, &outlen, inbuf, inlen)) and if(!EVP_CipherFinal_ex(ctx, outbuf, &outlen)) should say (what worked for me): if(!EVP_CipherUpdate(ctx, outbuf + outlen, &outlen, inbuf, inlen)) and if(!EVP_CipherFinal_ex(ctx, outbuf + outlen, &outlen)) It would be nice if there is a complete example that compiles and has a main() to run it. --Sam -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
