AesGcm

embassy_nrf::crypto::symmetric

Struct AesGcm 

Source 
pub struct AesGcm { /* private fields */ }
Expand description

AES in GCM (Galois/counter) authenticated mode, as in NIST SP 800-38D.

Not available on nRF52840 and nRF91.

Only 12-byte IVs are supported. The IV must be unique for every message. Reusing one breaks the security of the mode. The tag returned by Symmetric::aes_blocking_finish is 16 bytes.

Implementations§

Source§

impl AesGcm

Source

pub fn new(key: &[u8], iv: &[u8; 12]) -> Result<Self, Error>

Creates a GCM cipher with the given key and 12-byte IV.

The key is 16, 24 or 32 bytes.

Errors: InvalidKeyLength.
