Enum CryptoError 

#[non_exhaustive]
pub enum CryptoError {
    InvalidKeyLength,
    InvalidBlockSize,
    BadPadding,
    SessionKeyBase64(DecodeError),
}

Cryptographic failure modes encountered when encrypting requests or decrypting responses.

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.

InvalidKeyLength

3DES key was not 24 bytes long. Indicates a programming bug — the crate’s internals always produce 24-byte keys.

InvalidBlockSize

Ciphertext length was not a multiple of the 3DES block size (8 bytes).

BadPadding

PKCS7 padding verification failed during decryption. Usually means the session key is stale or the ciphertext was tampered with mid-flight.

SessionKeyBase64(DecodeError)

Session key returned by the server did not Base64-decode cleanly.

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 Eq for CryptoError

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<CryptoError> for Error

fn from(source: CryptoError) -> Self

Converts to this type from the input type.

impl From<DecodeError> for CryptoError

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl PartialEq for CryptoError

fn eq(&self, other: &CryptoError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
