    // 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.SetCryptAlgorithm("pbes2")
    crypt.SetPbesPassword("mySecretPassword")

    // Set the underlying PBE algorithm (and key length):
    crypt.SetPbesAlgorithm("aes")
    crypt.SetKeyLength(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.SetIterationCount(1024)

    // A hash algorithm needs to be set for PBES2:
    crypt.SetHashAlgorithm("sha256")

    // Indicate that the encrypted bytes should be returned
    // as a hex string:
    crypt.SetEncodingMode("hex")
