Errors while preparing or running XMLDSig signature verification.

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.

InvalidKeyPem

The provided PEM block could not be parsed as PEM input.

UnsupportedAlgorithm

The signature method is not an RSA PKCS#1 v1.5 algorithm.

Fields

uri: String

XMLDSig algorithm URI used for diagnostics.

InvalidKeyFormat

The provided PEM block was not a public key.

Fields

label: String

The PEM label that was actually supplied.

InvalidKeyDer

The provided DER bytes were not a valid SPKI-encoded public key.

KeyPolicy(PolicyViolation)

A structurally valid key violates the active key-strength policy.

KeyAlgorithmMismatch

The provided public key does not match the signature algorithm.

Fields

uri: String

XMLDSig algorithm URI used for diagnostics.

InvalidSignatureFormat

The provided ECDSA signature bytes were neither XMLDSig fixed-width nor ASN.1 DER encoded.

Trait Implementations

impl Debug for SignatureVerificationError

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

Formats the value using the given formatter.

impl Display for SignatureVerificationError

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

Formats the value using the given formatter.

impl Error for SignatureVerificationError

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<PolicyViolation> for SignatureVerificationError

fn from(source: PolicyViolation) -> Self

Converts to this type from the input type.

impl From<SignatureVerificationError> for DsigError

fn from(source: SignatureVerificationError) -> Self

Converts to this type from the input type.
