I am using AES_CBC with padding (using PKCS#5 to pad) on C++ side:
AES_set_encrypt_key( keyBuf, 128, &key )
keyBuf contains key string
key is the key generated
Block Lenght is 16
AES_cbc_encrypt (ibuf, obuf, lenpad, &key, iv, AES_ENCRYPT)
ibuf = input data
obuf = encrypted data
lenpad = length of data (input data length + pad data length)
key = key generated by AES_set_encrypt_key
iv = initialization vector
On java side:
I am decrypting using following:
SecretKey aesKey = new SecretKeySpec(KeSo.getKey(keyBuffer), "AES");
keyBuffer: is same as KeyBuf @ C++ side
Cipher cipherDec = Cipher.getInstance("AES/CBC/PKCS5Padding", "BC");
cipherDec.init(Cipher.DECRYPT_MODE, aesKey, iv);
cipherDec.doFinal(enc);
enc: data to be encrypted in byte.
Problem
=======
I was using libcrypto.0.9.8a and every thing was working fine.
But as a part of upgrade on Sun SPARC licrypto0.9.8a is changed to
libcrypto.0.9.8k and things became worst. Encryption is not giving any
problem but during decryption with the same code I am getting
BadPaddingException.
Please help me out, this problem has made my life hell.
Thanks
Ashutosh
