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.

MlKemKey

Invalid ML-KEM key encoding, parameter set or consistency check.

MlKemCiphertext

Invalid public ciphertext framing, never an implicit-rejection signal.

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 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
