Workaround for the deprecated EncryptBytes and DecryptBytes methods

Shows how to replace the deprecated DecryptBytes method. (Chilkat is moving away from the use of CkByteData.) CkPython

import chilkat

success = False

crypt = chilkat.CkCrypt2()

crypt.put_CryptAlgorithm("aes")
crypt.put_CipherMode("cbc")
crypt.put_KeyLength(128)
crypt.put_PaddingScheme(0)
crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex")
crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex")
crypt.put_EncodingMode("base64")

success = False

# ------------------------------------------------------------------------
# The EncryptBytes and DecryptBytes methods are deprecated and will eventually be removed.

unencryptedBytes = chilkat.CkByteData()
unencryptedBytes.appendEncoded("AABBCCDDEEFF01020304","hex")

encryptedBytes = chilkat.CkByteData()
decryptedBytes = chilkat.CkByteData()

success = crypt.EncryptBytes(unencryptedBytes,encryptedBytes)
success = crypt.DecryptBytes(encryptedBytes,decryptedBytes)

# ------------------------------------------------------------------------
# Replace the above CkByteData usage with the following code:
# (Chilkat is moving away from using CkByteData)

bd = chilkat.CkBinData()
bd.AppendEncoded("AABBCCDDEEFF01020304","hex")

# in-place encrypt
crypt.EncryptBd(bd)
print("Encrypted: " + bd.getEncoded("hex"))

# in-place decrypt
crypt.DecryptBd(bd)
print("Decrypted: " + bd.getEncoded("hex"))
