Struct EncryptionKey 

pub struct EncryptionKey { /* private fields */ }

Cryptographic key for encryption operations

Implementations

impl EncryptionKey

pub fn new(algorithm: EncryptionAlgorithm, key_data: Vec<u8>) -> Result<Self>

Create a new encryption key from raw bytes

pub fn from_password_pbkdf2( password: &str, salt: Option<&[u8]>, algorithm: EncryptionAlgorithm, ) -> Result<Self>

Derive a key from a password using PBKDF2

pub fn from_password_argon2( password: &str, salt: Option<&[u8]>, algorithm: EncryptionAlgorithm, ) -> Result<Self>

Derive a key from a password using Argon2

pub fn encrypt( &self, plaintext: &str, associated_data: Option<&[u8]>, ) -> Result<String>

Encrypt plaintext data

pub fn decrypt( &self, ciphertext: &str, associated_data: Option<&[u8]>, ) -> Result<String>

Decrypt ciphertext data

pub fn encrypt_chacha20( &self, plaintext: &str, _associated_data: Option<&[u8]>, ) -> Result<String>

Encrypt text using ChaCha20-Poly1305 authenticated encryption

Arguments

• plaintext - Text to encrypt
• _associated_data - Optional associated data for authenticated encryption (currently unused)

Returns

Base64-encoded ciphertext with prepended nonce

pub fn decrypt_chacha20( &self, ciphertext: &str, _associated_data: Option<&[u8]>, ) -> Result<String>

Decrypt text using ChaCha20-Poly1305 authenticated encryption

Arguments

• ciphertext - Base64-encoded ciphertext with prepended nonce
• _associated_data - Optional associated data (must match encryption) (currently unused)

Returns

Decrypted plaintext as a string
