Trait rustls::crypto::hmac::Hmac

source ·
pub trait Hmac: Send + Sync {
    // Required methods
    fn with_key(&self, key: &[u8]) -> Box<dyn Key>;
    fn hash_output_len(&self) -> usize;
}
Expand description

A concrete HMAC implementation, for a single cryptographic hash function.

You should have one object that implements this trait for HMAC-SHA256, another for HMAC-SHA384, etc.

Required Methods§

source

fn with_key(&self, key: &[u8]) -> Box<dyn Key>

Prepare to use key as a HMAC key.

source

fn hash_output_len(&self) -> usize

Give the length of the underlying hash function. In RFC2104 terminology this is L.
