=================================================================
KeyGenerator key_gen = KeyGenerator.getInstance("Rijndael");
SecretKey aes_key = (SecretKey)key_gen.generateKey();
Cipher aes = Cipher.getInstance("Rijndael/CBC/PKCS5Padding", "IAIK");
aes.init(Cipher.ENCRYPT_MODE, aes_key);
byte[] crypted = aes.doFinal(bb.array());
byte[] iv = aes.getIV();
=================================================================
and the C program:
=================================================================
char byte_aes_key[16]; // <---- the byte array obtained with aes_key.getEncoded() in java
char byte_iv[16]; // <---- The iv from the java program
EVP_CIPHER_CTX ctx;
EVP_DecryptInit(&ctx, EVP_aes_128_cbc(), byte_aes_key, byte_iv);
int outlen;
res = EVP_DecryptUpdate(&ctx, decrypted, &outlen, encrypted, encryptedlen);
=================================================================
but the decrypted message isn't correct. Can anybody give me any suggestion?
Thanks in advance.
