Errors thrown by implementations.

Variants

KdfExpandInvalidPrkLen

Expand() failed due to invalid PRK length.

This error is returned when:

1. For HKDF-Expand, the PRK length MUST be at least Nh bytes.

KdfExpandInvalidOutputLen

Expand() failed due to invalid output length.

This error is returned when:

1. For HKDF-Expand, the requested output length MUST NOT exceed the maximum allowed length (255 * Nh).

KdfUnsupported

The KDF algorithm is unknown or unsupported by the crypto backend.

KemDeriveKeyPair

Failed to derive a key pair from the input keying material.

This error is returned when:

1. Failed to generate valid private key from the input keying material in 255 iterations.

KemMalformedSkX

The skX is malformed and cannot be used as a private key for the KEM.

KemMalformedPkX

The pkX is malformed and cannot be used as a public key for the KEM.

KemOpUnsupported

The operation is not supported by the KEM algorithm.

This error is returned when the KEM algorithm does not support the requested operation, e.g., Encap or Decap.

KemUnsupported

The KEM algorithm is unknown or unsupported by the crypto backend.

AeadInvalidKey

Invalid key for the AEAD algorithm.

AeadInvalidNonce

Invalid nonce for the AEAD algorithm.

AeadInvalidCt

The cipher text ct is invalid for the AEAD algorithm.

This error is returned when:

1. The cipher text length is less than the tag length.

AeadSeal

Error sealing an AEAD cipher text.

AeadOpen

Error opening an AEAD cipher text.

AeadUnsupported

Unknown or unsupported AEAD algorithm.

InsufficientRandomness

Insufficient randomness to perform the operation.

This error is rarely returned.

Unspecified

Unspecified error

Custom(Box<dyn Error + Send + Sync + 'static>)

A crypto library 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, f: &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>)
