Struct RsaParameters 

pub struct RsaParameters { /* private fields */ }

Available on crate features aws-lc and crypto and std only.

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.

Implementations

impl RsaParameters

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

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.
