Enum pkcs1::Version

#[repr(u8)]
pub enum Version {
    TwoPrime,
    Multi,
}

Version identifier for PKCS#1 documents as defined in RFC 8017 Appendix 1.2.

version is the version number, for compatibility with future revisions of this document. It SHALL be 0 for this version of the document, unless multi-prime is used; in which case, it SHALL be 1.

Version ::= INTEGER { two-prime(0), multi(1) }
   (CONSTRAINED BY
   {-- version must be multi if otherPrimeInfos present --})

Variants

TwoPrime

Denotes a two-prime key

Multi

Denotes a multi (i.e. multi-prime) key

Implementations

impl Version

pub fn is_multi(self) -> bool

Is this a multi-prime RSA key?

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl<'a> Decode<'a> for Version

fn decode<R: Reader<'a>>(decoder: &mut R) -> Result<Self>

Attempt to decode this message using the provided decoder.

fn from_der(bytes: &'a [u8]) -> Result<Self, Error>

Parse Self from the provided DER-encoded byte slice.

impl Encode for Version

fn encoded_len(&self) -> Result<Length>

Compute the length of this value in bytes when encoded as ASN.1 DER.

fn encode(&self, writer: &mut impl Writer) -> Result<()>

Encode this value as ASN.1 DER using the provided Writer.

fn encode_to_slice<'a>(&self, buf: &'a mut [u8]) -> Result<&'a [u8], Error>

Encode this value to the provided byte slice, returning a sub-slice containing the encoded message.

fn encode_to_vec(&self, buf: &mut Vec<u8, Global>) -> Result<Length, Error>

Available on crate feature alloc only.

Encode this message as ASN.1 DER, appending it to the provided byte vector.

fn to_der(&self) -> Result<Vec<u8, Global>, Error>

Available on crate feature alloc only.

Encode this type as DER, returning a byte vector.

impl FixedTag for Version

const TAG: Tag = Tag::Integer

ASN.1 tag

impl From<Version> for u8

fn from(version: Version) -> Self

Converts to this type from the input type.

impl Ord for Version

fn cmp(&self, other: &Version) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Version> for Version

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<Version> for Version

fn partial_cmp(&self, other: &Version) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<u8> for Version

type Error = Error

The type returned in the event of a conversion error.

fn try_from(byte: u8) -> Result<Version, Error>

Performs the conversion.
