Demonstrates PBES2 encryption Chilkat2-Python

import chilkat2

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

crypt = chilkat2.Crypt2()

# Set properties for PBES2 encryption:

# When the encryption algorithm is set to "pbes2",
# Chilkat will automatically derive the actual secret key using PBKDF2 and
# the specified paramters: password, salt, iteration count, hash function, and desired key length.

crypt.CryptAlgorithm = "pbes2"
crypt.PbesPassword = "mySecretPassword"

# Set the underlying PBE algorithm (and key length):
crypt.PbesAlgorithm = "aes"
crypt.KeyLength = 256

crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex")

# Give it some salt:
crypt.SetEncodedSalt("0102030405060708","hex")

# A higher iteration count makes the algorithm more
# computationally expensive and therefore exhaustive
# searches (for breaking the encryption) is more difficult:
crypt.IterationCount = 1024

# A hash algorithm needs to be set for PBES2:
crypt.HashAlgorithm = "sha256"

# Indicate that the encrypted bytes should be returned
# as a hex string:
crypt.EncodingMode = "hex"

plainText = "To be encrypted."

encryptedText = crypt.EncryptStringENC(plainText)

print(encryptedText)

# Now decrypt:
decryptedText = crypt.DecryptStringENC(encryptedText)

print(decryptedText)
