Enum Pbkdf2Error 

#[non_exhaustive]
pub enum Pbkdf2Error {
    InvalidIterations,
    OutputTooLong,
}

Available on (crate features hmac or hkdf or kmac or ed25519 or x25519 or phc-strings or argon2 or scrypt) and crate feature pbkdf2 only.

Invalid PBKDF2 parameters.

Returned when the iteration count is zero or the derived key length exceeds the RFC 2898 maximum of (2^32 − 1) × hLen.

Examples

use rscrypto::{Pbkdf2Sha256, auth::Pbkdf2Error};

let err = Pbkdf2Sha256::derive_key(b"pw", b"salt", 0, &mut [0u8; 32]);
assert_eq!(err, Err(Pbkdf2Error::InvalidIterations));

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.

InvalidIterations

The iteration count must be at least 1. NIST/OWASP policy minima are documented on Pbkdf2Sha256::MIN_RECOMMENDED_ITERATIONS and Pbkdf2Sha512::MIN_RECOMMENDED_ITERATIONS.

OutputTooLong

The requested output length exceeds (2^32 − 1) × hLen.

Trait Implementations

impl Clone for Pbkdf2Error

fn clone(&self) -> Pbkdf2Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pbkdf2Error

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

Formats the value using the given formatter.

impl Display for Pbkdf2Error

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

Formats the value using the given formatter.

impl Error for Pbkdf2Error

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 Hash for Pbkdf2Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Pbkdf2Error

fn eq(&self, other: &Pbkdf2Error) -> 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.
