AES CFB Mode Encryption

See more Encryption Examples

Demonstrates how to encrypt using AES CFB (Cipher Feedback) mode. Rust

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

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

crypt.set_crypt_algorithm("aes");
crypt.set_cipher_mode("cfb");
crypt.set_key_length(256);

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

let iv_hex = "000102030405060708090A0B0C0D0E0F".to_string();
crypt.set_encoded_iv(&iv_hex, "hex");

// The secret key must equal the size of the key.  For
// 256-bit encryption, the binary secret key is 32 bytes.
let key_hex = "603deb1015ca71be2b73aef0857d77811f352c073b6108d72d9810a30914dff4".to_string();
crypt.set_encoded_key(&key_hex, "hex");

// Encrypt a string...
let enc_str = crypt.encrypt_string_enc("Good night, good night! parting is such sweet sorrow, That I shall say good night till it be morrow. --  William Shakespeare").unwrap_or_default();
println!("{}", enc_str);

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

decrypt.set_crypt_algorithm("aes");
decrypt.set_cipher_mode("cfb");
decrypt.set_key_length(256);
decrypt.set_encoding_mode("hex");
decrypt.set_encoded_iv(&iv_hex, "hex");
decrypt.set_encoded_key(&key_hex, "hex");

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