Struct devolutions_crypto::ciphertext::Ciphertext

pub struct Ciphertext { /* fields omitted */ }

A versionned ciphertext. Can be either symmetric or asymmetric.

Methods

impl Ciphertext

pub fn decrypt(&self, key: &[u8]) -> Result<Vec<u8>, Error>

Decrypt the data blob using a key.

Arguments

• key - Key to use. The recommended size is 32 bytes.

Returns

Returns the decrypted data.

Example

use devolutions_crypto::ciphertext::{ encrypt, CiphertextVersion};

let data = b"somesecretdata";
let key = b"somesecretkey";

let encrypted_data = encrypt(data, key, CiphertextVersion::Latest).unwrap();
let decrypted_data = encrypted_data.decrypt(key).unwrap();

assert_eq!(data.to_vec(), decrypted_data);

pub fn decrypt_asymmetric(
    &self,
    private_key: &PrivateKey
) -> Result<Vec<u8>, Error>

Decrypt the data blob using a PrivateKey.

Arguments

• private_key - Key to use. Must be the one in the same keypair as the PublicKey used for encryption.

Returns

Returns the decrypted data.

Example

use devolutions_crypto::ciphertext::{ encrypt_asymmetric, CiphertextVersion };
use devolutions_crypto::key::{ generate_keypair, KeyVersion };

let data = b"somesecretdata";
let keypair = generate_keypair(KeyVersion::Latest);

let encrypted_data = encrypt_asymmetric(data, &keypair.public_key, CiphertextVersion::Latest).unwrap();
let decrypted_data = encrypted_data.decrypt_asymmetric(&keypair.private_key).unwrap();

assert_eq!(decrypted_data, data);
