Implementations

impl AsymmetricSignature

pub fn is_alg_permitted(self, alg: AsymmetricSignature) -> bool

Check if the alg given for a cryptographic operation is permitted to be used with this algorithm as a policy

Example

use psa_crypto::types::algorithm::{AsymmetricSignature, SignHash, Hash};
assert!(AsymmetricSignature::RsaPkcs1v15Sign { hash_alg: SignHash::Any }
        .is_alg_permitted(AsymmetricSignature::RsaPkcs1v15Sign {
            hash_alg:  SignHash::Specific(Hash::Sha1)
        })
       );
assert!(!AsymmetricSignature::RsaPkcs1v15Sign { hash_alg: SignHash::Specific(Hash::Sha256) }
        .is_alg_permitted(AsymmetricSignature::RsaPkcs1v15Sign {
            hash_alg:  SignHash::Specific(Hash::Sha1)
        })
       );

pub fn is_rsa_alg(self) -> bool

Check if this is a RSA algorithm

pub fn is_ecc_alg(self) -> bool

Check if this is an ECC algorithm

pub fn is_hash_len_permitted(self, hash_len: usize) -> bool
