Using python M2Crypto AES cipher with java

I have the following python code:

def AES_build_cipher(key, iv, op): return EVP.Cipher(alg='aes_128_cbc', key=key, iv=iv, op=op, padding=True) # PKCS#5 paddig def AES_encrypt(key, msg, iv): # key, iv -> bytes, msg -> text if iv is None: raise ValueError("IV must be defined!") # Return the encryption function def encrypt(data): cipher = AES_build_cipher(key, iv, ENCRYPTION) v = cipher.update(data) v = v + cipher.final() del cipher return v return encrypt(msg) 

It works ok (encryption/decryption via M2Crypto).

Java code for decryption:

public static String AESDecrypt(String b64data, byte[] key, byte[] iv) throws CipherException { try { aesCipher_ = Cipher.getInstance("AES/CBC/PKCS5Padding"); aesCipher_.init(Cipher.DECRYPT_MODE, new SecretKeySpec(key, "AES"), new IvParameterSpec(iv)); final byte[] byteData = Base64.decode(b64data, Base64.DEFAULT); final byte[] decryptedData = aesCipher_.doFinal(byteData); return new String(decryptedData); } catch (Exception e) { throw new CipherException(e); } } 

data:

• iv = 8b9123ba6712612fb98452aac3854838 (hex representation)
• text = 12345678901234567890 (simple text)
• ciphertext = af87d97bf9779efcff0386d4eaee18619dc8f1fe7c5adea2a91657f53491bc2 (hex representation)
• password = 791a06ee369dc2f842c655f6bec8ce2 (hex representation)

Result:

• Exp:'12345678901234567890'
• Got:'1���$V��c�J�}7890'

Looks like something wrong with IV (first 16 bytes of result). But I have no idea what I missed.
