Encrypt / Decrypt Secure Strings

See more Encryption Examples

Demonstrates how to use the EncryptSecureENC and DecryptSecureENC methods to encrypt/decrypt secure strings. These methods were added in Chilkat v9.5.0.71 (released January 2018). CkPython

import sys
import chilkat

success = False

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# Load the secure string with some text.
secStr1 = chilkat.CkSecureString()
success = secStr1.LoadFile("qa_data/txt/helloWorld.txt","utf-8")
if (success != True):
    print("Failed to load helloWorld.txt")
    sys.exit()

crypt = chilkat.CkCrypt2()

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

# Return the base64 encoded encrypted contents of secStr1.
encryptedStr = crypt.encryptSecureENC(secStr1)
print("Encrypted string: " + encryptedStr)

# Output:
# Encrypted string: qiq+IFhcjTkEIkZyf31V/g==

# Decrypt to secStr2:
secStr2 = chilkat.CkSecureString()
crypt.DecryptSecureENC(encryptedStr,secStr2)

# Access the contents of secStr2
print("Decrypted string: " + secStr2.access())

# Output:
# Decrypted string: Hello World!
