Structured invalid-input reasons returned by cryptographic providers.

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.

EcdhKey

An EC scalar or peer point is not valid for the selected named curve.

ConsumedEphemeralKey

An operation-owned ephemeral sender key has already been consumed.

DhKey

Finite-field domain, scalar, or peer fails DH validation.

HkdfParameters

An HKDF request violates the primitive’s parameter or output contract.

Pbkdf2Parameters

A PBKDF2 request has invalid iterations, length, or unrelated context.

ConcatKdfParameters

A ConcatKDF request violates its bit-string or counter contract.

LegacyDhKdfParameters

A legacy DH KDF request has invalid framing or exceeds its byte counter.

PrimitiveInitialization(&'static str)

A primitive rejected a key or IV after its public preconditions were checked.

AesCbcFraming

AES-CBC input does not contain an IV followed by complete blocks.

AesCbcCiphertext

AES-CBC block decryption failed.

AesGcmFraming

AES-GCM input does not contain a nonce and authentication tag.

AesKeyWrapFraming

AES key-wrap input or output framing is invalid.

LegacyRsaOaepMgf

👎Deprecated:

explicit MGF parameters are supported for both RSA-OAEP URIs

Legacy compatibility variant retained for downstream construction and matching.

Explicit MGF parameters are valid for both RSA-OAEP URIs, so current providers never return this reason.

Trait Implementations

impl Clone for ProviderInputError

fn clone(&self) -> Self

impl Eq for ProviderInputError

impl Error for ProviderInputError

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
