Struct cryptoki::mechanism::aead::GcmParams

pub struct GcmParams<'a> { /* private fields */ }

Parameters for AES-GCM.

Implementations

impl<'a> GcmParams<'a>

pub fn new(iv: &'a [u8], aad: &'a [u8], tag_bits: Ulong) -> Self

Construct GCM parameters.

Arguments

iv - The initialization vector. This must be non-empty. In PKCS#11 2.40, the maximum length of the IV is 256 bytes. A 12-byte IV may be processed more efficiently than other lengths.

aad - The additional authenticated data. This data is authenticated but not encrypted. This may be between 0 and 2^32-1 bytes.

tag_bits - The length, in bits, of the authentication tag. Must be between 0 and 128. The tag is appended to the end of the ciphertext.

Panics

This function panics if the length of iv or aad does not fit into an Ulong.

pub fn iv(&self) -> &'a [u8]

The initialization vector.

pub fn aad(&self) -> &'a [u8]

The additional authenticated data.

pub fn tag_bits(&self) -> Ulong

The length, in bits, of the authentication tag.

Trait Implementations
