Workaround for the deprecated EncryptString and DecryptString methods

Shows how to replace the deprecated EncryptString and DecryptString methods. (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")

success = False

crypt.put_Charset("utf-8")
plainText = "text to be encrypted"

# ------------------------------------------------------------------------
# The EncryptString and DecryptString methods are deprecated:

encryptedBytes = chilkat.CkByteData()
success = crypt.EncryptString(plainText,encryptedBytes)

decryptedStr = crypt.decryptString(encryptedBytes)
print("Decrypted: " + decryptedStr)

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

bd = chilkat.CkBinData()
bd.AppendString(plainText,"utf-8")

# in-place encrypt
crypt.EncryptBd(bd)

# in-place decrypt
crypt.DecryptBd(bd)
decryptedStr = bd.getString("utf-8")
print("Decrypted: " + decryptedStr)
