Struct HmacSha384Keyed 

pub struct HmacSha384Keyed(/* private fields */);

Pre-keyed HMAC-SHA-384 instance; implements StreamingMac.

Created via HmacSha384::new_keyed. The key is bound at construction time; subsequent calls to update feed message chunks, and finalize or verify consume the instance.

Implementations

impl HmacSha384Keyed

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

Create a pre-keyed HMAC-SHA-384 instance.
