}

All possible errors from cryptographic operations.

Variants

Base64(DecodeError)

Base64 decoding failed.

Decryption

Decryption failed (wrong key, corrupted ciphertext, or MAC mismatch).

InvalidLength

A key or salt has the wrong byte length.

Fields

expected: usize

Expected byte count.

got: usize

Actual byte count.

TooShort

Ciphertext is too short to contain the expected components.

InvalidKeyHash

The key_hash string is not in the expected {salt}$argon2id format.

InvalidRecoveryKey

A recovery key contains characters outside the allowed base32 alphabet.

Kdf(String)

The Argon2id key derivation failed.

Hybrid(String)

An error in the hybrid PQ KEM layer.

Signature(String)

An error in the hybrid PQ signature layer.

Vrf(String)

An error in the verifiable random function (ECVRF) layer that is not a plain length mismatch — e.g. a proof component that is not a valid curve point, or hash-to-curve exhausting its counter budget. A verification failure of an otherwise well-formed proof is reported as Ok(None) from ecvrf_verify, not as this error.

Utf8(FromUtf8Error)

Decrypted bytes are not valid UTF-8.

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.

impl From<DecodeError> for CryptoError

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for CryptoError

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.
