Struct CredentialIdLength 

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

The length of credentialId that should be randomly generated during a credential creation operation.

The value has a maximum of 64 per the webauthn specification. The minimum is a library enforced as 16.

It is recommended to randomize this if possible to avoid authenticator fingerprinting.

Implementations

impl CredentialIdLength

pub const DEFAULT: Self

The default length of a credentialId to generate.

This value is the same as Self::default, but available in const contexts.

pub fn randomized<Rng: RngBackend>() -> Self

Generates and returns a uniformly random CredentialIdLength.
