Enum OpaqueError 

pub enum OpaqueError {
    ServerAuthenticationError,
    ClientAuthenticationError,
    EnvelopeRecoveryError,
    InvalidMac,
    DeserializationError,
    InternalError(&'static str),
    InvalidInput(&'static str),
}

Errors that can occur during the OPAQUE protocol.

Security

The distinct error variants are useful for server-side logging and debugging, but they must not be exposed verbatim to remote clients. Returning different error messages for ServerAuthenticationError, EnvelopeRecoveryError, and InvalidMac can serve as an oracle, allowing an attacker to distinguish “wrong password” from “server MAC failure” from other conditions. Always map all authentication-related errors to a single opaque response before sending over the wire.

Variants

ServerAuthenticationError

The server’s MAC did not verify during login.

ClientAuthenticationError

The client’s MAC did not verify during login.

EnvelopeRecoveryError

The envelope could not be recovered (wrong password).

InvalidMac

A MAC verification failed.

DeserializationError

A message could not be deserialized.

InternalError(&'static str)

An internal error occurred.

InvalidInput(&'static str)

Invalid input was provided.

Trait Implementations

impl Debug for OpaqueError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for OpaqueError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for OpaqueError

Available on crate feature std only.

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<OpaqueError> for PakeError

fn from(e: OpaqueError) -> Self

Converts to this type from the input type.

impl From<PakeError> for OpaqueError
