A provider-neutral cryptographic failure.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoDefaultProvider

No built-in default provider was compiled.

UnsupportedAlgorithm(CryptoAlgorithm)

The provider does not implement an algorithm.

InvalidKeyLength

A key has the wrong length.

Fields

expected: usize

Required length.

actual: usize

Supplied length.

InvalidNonceLength

A nonce or IV has the wrong length.

Fields

expected: usize

Required length.

actual: usize

Supplied length.

InvalidTagLength

An authentication tag has the wrong length.

Fields

expected: usize

Required length.

actual: usize

Supplied length.

InvalidPublicKey

Public-key bytes are malformed or use the wrong encoding.

InvalidPrivateKey

Private-key bytes are malformed or incompatible with the scheme.

AuthenticationFailed

Decryption, padding, or tag authentication failed.

InvalidSignature

Signature verification failed.

RandomnessFailed

The cryptographically secure random source failed.

OutputTooSmall

A caller-owned output buffer is too small.

Fields

required: usize

Required length.

actual: usize

Supplied length.

Provider(String)

Sanitized provider diagnostic context.

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 Eq for CryptoError

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.

impl PartialEq for CryptoError

fn eq(&self, other: &CryptoError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
