Expand description

AES-GCM cipher for encrypting and decrypting data.

Implementations§

Source§

impl AesGcmCipher

Source

pub const NONCE_LEN: usize = 12usize

AES-GCM nonce length in bytes (96 bits).

Source

pub const TAG_LEN: usize = 16usize

AES-GCM authentication tag length in bytes (128 bits).

Source

pub fn new(key: SecureKey) -> Self

Creates a new cipher with the specified key.

Source

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

Encrypts data using AES-GCM.

§Arguments
  • plaintext - The data to encrypt
  • aad - Additional authenticated data (optional)
§Returns

The encrypted data in the format: [12-byte nonce][ciphertext][16-byte auth tag] This matches the Java implementation format for compatibility.

Source

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

Decrypts data using AES-GCM.

§Arguments
  • ciphertext - The encrypted data with format: [12-byte nonce][encrypted data][16-byte auth tag]
  • aad - Additional authenticated data (must match encryption)
§Returns

The decrypted plaintext.
