Struct HS256

pub struct HS256 { /* private fields */ }

Available on crate feature hmac-sha2 only.

HMAC using SHA2-256.

This algorithm is required to be implemented (i.e. available) according to section 3.1 of RFC 7518, but jwt2 does not enforce this requirement. In the terms of RFCs this crate treats HS256’s “Required” as a “Recommended”.

Implementations

impl HS256

pub fn new(key: &[u8]) -> Result<Self, ConstructError>

Creates a HS256 instance.

See the security considerations of this module.

impl HS256

pub fn generate_key<R>(rng: &mut R) -> Vec<u8>

where R: CryptoRngCore,

Available on crate feature rand only.

Generates a suitable key for this algorithm.
