Errors that can occur during cryptographic operations

Variants

UnknownAlgorithm(String)

Returned when an unrecognized algorithm identifier is encountered.

This typically occurs when parsing Base64-encoded data with an unknown algorithm prefix (e.g., not ‘B’ for Blake3 or ‘E’ for Ed25519).

InvalidHashFormat(String)

Returned when hash data is malformed or has incorrect structure.

Common causes:

• Missing algorithm identifier
• Incorrect data length for the algorithm
• Corrupted Base64 encoding

InvalidSignatureFormat(String)

Returned when signature data is malformed or has incorrect structure.

Common causes:

• Missing algorithm identifier
• Incorrect signature length for the algorithm
• Corrupted Base64 encoding

SignatureVerificationFailed

Returned when cryptographic signature verification fails.

This indicates that either:

• The signature was not created by the claimed signer
• The signed data has been modified
• The signature is invalid or corrupted

InvalidPublicKey(String)

Returned when a public key is invalid or malformed.

Common causes:

• Incorrect key length
• Invalid key format for the algorithm
• Corrupted key data

InvalidSecretKey(String)

Returned when a secret key is invalid or malformed.

Common causes:

• Incorrect key length
• Invalid key format
• Decryption failure from secure storage

MissingSecretKey

Returned when attempting signing operations on a verification-only instance.

This occurs when a signer is created from a public key only (using from_public_key()) and then used to sign data. Such instances can only verify signatures, not create them.

Base64DecodeError(String)

Returned when Base64 decoding fails.

InvalidDataLength

Returned when data has an unexpected length.

This is a validation error that occurs when the actual data size doesn’t match the expected size for a specific algorithm or operation.

Fields

expected: usize

actual: usize

SerializationError(String)

Returned when Borsh serialization/deserialization fails.

HashError(String)

Returned when hash computation or verification fails.

SigningError(String)

Returned when a signing operation fails.

UnsupportedAlgorithm(String)

Returned when an algorithm is not supported by this implementation.

This occurs when attempting to use a cryptographic algorithm that is recognized but not implemented in the current version.

InvalidDerFormat(String)

Returned when PKCS#8 DER parsing fails.

Trait Implementations

impl Clone for CryptoError

fn clone(&self) -> CryptoError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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.
