}

Errors produced by cryptographic helper functions.

Variants

PasswordHash(String)

Password hashing, parsing, or verification failed.

PasswordHashPolicy(String)

A password-hash policy is internally inconsistent or unsupported.

PasswordHashVerificationLimit

A stored password hash exceeds the configured verification resource budget.

Fields

parameter: &'static str

PHC parameter or derived value that exceeded the limit.

actual: u64

Value read from the stored password hash.

maximum: u64

Maximum value accepted by the verification policy.

MessageAuthentication(String)

Keyed message authentication initialization failed.

InvalidSecretEnvelopePolicy

The caller supplied an invalid product-owned secret-envelope context or policy value.

InvalidSecretEnvelope

The stored secret envelope is malformed.

UnsupportedSecretEnvelopeVersion

The stored secret envelope uses an unsupported version.

SecretEnvelopeKeyDerivation

The encryption key could not be derived for the supplied context.

SecretEnvelopeEncryption

Authenticated encryption failed.

SecretEnvelopeAuthentication

Authentication or decryption failed.

Implementations

impl CryptoError

pub fn password_hash(error: impl Display) -> Self

Creates a password-hash error from any displayable error value.

pub fn password_hash_policy(error: impl Display) -> Self

Creates a password-hash policy error.

pub fn message_authentication(error: impl Display) -> Self

Creates a keyed message-authentication error.

Trait Implementations

impl Debug for CryptoError

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

Formats the value using the given formatter.

impl Display for CryptoError

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

Formats the value using the given formatter.

impl Error for CryptoError

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.
