PBES2 Password-Based Encryption

See more Encryption Examples

Demonstrates PBES2 encryption Rust

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

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

// 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.set_crypt_algorithm("pbes2");
crypt.set_pbes_password("mySecretPassword");

// Set the underlying PBE algorithm (and key length):
crypt.set_pbes_algorithm("aes");
crypt.set_key_length(256);

crypt.set_encoded_iv("000102030405060708090A0B0C0D0E0F", "hex");

// Give it some salt:
crypt.set_encoded_salt("0102030405060708", "hex");

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

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

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

let plain_text = "To be encrypted.".to_string();

let encrypted_text = crypt.encrypt_string_enc(&plain_text).unwrap_or_default();

println!("{}", encrypted_text);

// Now decrypt:
let decrypted_text = crypt.decrypt_string_enc(&encrypted_text).unwrap_or_default();

println!("{}", decrypted_text);
