Struct RsaParameters 

pub struct RsaParameters {
    digest_alg: &'static Algorithm,
    padding: &'static RsaPadding,
    pss_salt_length: RsaPssSaltLength,
    range: RangeInclusive<u32>,
    verification_alg: &'static RsaVerificationAlgorithmId,
}

Parameters for RSA verification.

Two values are equal when they denote the same verification algorithm, e.g. RSA_PKCS1_2048_8192_SHA256. Algorithms differing in digest algorithm, padding scheme, RSA PSS salt length, or modulus size range compare unequal. In short, it is equality of configuration, not equality of effective behavior.

Fields

digest_alg: &'static Algorithm

padding: &'static RsaPadding

pss_salt_length: RsaPssSaltLength

range: RangeInclusive<u32>

verification_alg: &'static RsaVerificationAlgorithmId

Implementations

impl RsaParameters

pub(crate) fn digest_algorithm(&self) -> &'static Algorithm

pub(crate) fn padding(&self) -> &'static RsaPadding

pub(crate) fn pss_salt_length(&self) -> RsaPssSaltLength

pub(crate) fn bit_size_range(&self) -> &RangeInclusive<u32>

impl RsaParameters

pub(crate) const fn new( digest_alg: &'static Algorithm, padding: &'static RsaPadding, range: RangeInclusive<u32>, verification_alg: &'static RsaVerificationAlgorithmId, ) -> Self

pub const fn with_pss_salt_length(self, saltlen: RsaPssSaltLength) -> Self

Sets the RSA-PSS salt length to the given value.

This is ignored for PKCS#1 v1.5 parameters.

Due to the requirement of 'static references to the current type in verification APIs, it is not possible to directly give the result of this method to them, nor simply re-borrow it. Instead either the inline &const { rsa_param.with_pss_salt_length(...) } expression syntax should be used, or the following if Rust below 1.79 is used:

use aws_lc_rs::signature::{self, RsaPssSaltLength};

const VERIFY_ALG: signature::RsaParameters =
    signature::RSA_PSS_2048_8192_SHA256.with_pss_salt_length(RsaPssSaltLength::Custom(123));
// Now use `VERIFY_ALG` instead of `RSA_PSS_2048_8192_SHA256`.

pub fn public_modulus_len(public_key: &[u8]) -> Result<u32, Unspecified>

Parses a DER-encoded RSAPublicKey structure (RFC 8017) to determine its size in bits.

Errors

error::Unspecified on parse error.

pub fn min_modulus_len(&self) -> u32

Minimum modulus length in bits.

pub fn max_modulus_len(&self) -> u32

Maximum modulus length in bits.
