Struct IpcCipher 

pub struct IpcCipher { /* private fields */ }

Encrypted message format: [nonce (12 bytes)][ciphertext (variable)][auth tag (16 bytes, included in ciphertext)]

Implementations

impl IpcCipher

pub fn from_session_token(token: &str) -> Self

Create a new cipher from a session token

The session token is hashed with SHA-256 to derive the encryption key. This ensures a consistent 256-bit key regardless of token length.

pub fn encrypt(&self, plaintext: &[u8]) -> Result<Vec<u8>>

Encrypt a message

Returns the encrypted message with nonce prepended. Format: [nonce (12 bytes)][ciphertext + auth tag]

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

Decrypt a message

Expects format: [nonce (12 bytes)][ciphertext + auth tag]

pub fn encrypt_string(&self, plaintext: &str) -> Result<String>

Encrypt a string message to base64

Convenient method for encrypting string messages.

pub fn decrypt_string(&self, encrypted_b64: &str) -> Result<String>

Decrypt a base64 message to string

Convenient method for decrypting string messages.
