Struct SecretBytes 

pub struct SecretBytes { /* private fields */ }

HMAC key material for the audit chain.

Empty and all-whitespace keys are rejected. The key intentionally has no public Debug, Display, or AsRef<[u8]> implementation.

Implementations

pub fn new(bytes: impl Into<Vec<u8>>) -> Result<Self, EmptyKeyError>

Wraps owned bytes as an HMAC secret.

Errors

Returns EmptyKeyError if the byte slice is empty or all whitespace.

pub fn try_from_slice(bytes: &[u8]) -> Result<Self, EmptyKeyError>

Copies the slice and wraps it as an HMAC secret.

Errors

Returns EmptyKeyError if the slice is empty or all whitespace.
