2-Key Triple DES (112 bits)

See more Encryption Examples

Demonstrates 2-Key Triple DES encryption (112-bit 3DES encryption). Rust

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

let crypt = chilkat::Crypt2::new();

// Specify 3DES for the encryption algorithm:
crypt.set_crypt_algorithm("3des");

crypt.set_cipher_mode("ecb");

// For 2-Key Triple-DES, use a key length of 128
// (Given that each byte's msb is a parity bit, the strength is really 112 bits).
crypt.set_key_length(128);

// Pad with zeros
crypt.set_padding_scheme(3);

// EncodingMode specifies the encoding of the output for
// encryption, and the input for decryption.
// It may be "hex", "url", "base64", or "quoted-printable".
crypt.set_encoding_mode("hex");

// Let's create a secret key by using the MD5 hash of a password.
// The Digest-MD5 algorithm produces a 16-byte hash (i.e. 128 bits)
crypt.set_hash_algorithm("md5");
let key_hex = crypt.hash_string_enc("secretPassword").unwrap_or_default();

// Set the encryption key:
crypt.set_encoded_key(&key_hex, "hex");

// Encrypt
let enc_str = crypt.encrypt_string_enc("The quick brown fox jumped over the lazy dog").unwrap_or_default();
println!("{}", enc_str);

// Now decrypt:
let dec_str = crypt.decrypt_string_enc(&enc_str).unwrap_or_default();
println!("{}", dec_str);
