init(authenticating:key:)
Computes a hash-based message authentication code (HMAC) for the given message using the given key.
init(authenticating message: some Sequence<UInt8>, key: some Collection<UInt8>)
This initializer computes an instance of MessageAuthenticationKey
and uses it to generate an instance of Self
. If you are reusing the same key
multiple times, it is more efficient to compute the message authentication key externally and call its MessageAuthenticationKey.authenticate(_:)
method instead.
