Struct wolf_crypto::aes::Tag

pub struct Tag { /* private fields */ }

Represents the authentication tag produced by AES-GCM encryption.

Implementations

impl Tag

pub const CAPACITY: usize = 16usize

The size of the authentication tag in bytes.

pub const fn new(inner: [u8; 16]) -> Self

Creates a new Tag instance from a 16-byte array.

Arguments

• inner - A 16-byte array containing the authentication tag.

Returns

A new Tag instance.

pub const fn new_zeroed() -> Self

Creates a new Tag instance filled with zeros.

This is typically used to create a tag buffer that will be filled by an encryption operation.

Returns

A new Tag instance with all bytes set to zero.

Example

use wolf_crypto::aes::gcm::Tag;

let tag = Tag::new_zeroed();
assert_eq!(tag.as_slice(), &[0u8; 16]);

pub const fn take(self) -> [u8; 16]

Consumes the Tag and returns the underlying 16-byte array.

pub const fn as_slice(&self) -> &[u8]

Returns a reference to the tag as a byte slice.
