Struct rsa::pss::VerifyingKey

pub struct VerifyingKey<D>where
    D: Digest,{ /* private fields */ }

Verifying key for checking the validity of RSASSA-PSS signatures as described in RFC8017 § 8.1.

Implementations

impl<D> VerifyingKey<D>where D: Digest,

pub fn new(key: RsaPublicKey) -> Self

Create a new RSASSA-PSS verifying key. Digest output size is used as a salt length.

pub fn new_with_salt_len(key: RsaPublicKey, salt_len: usize) -> Self

Create a new RSASSA-PSS verifying key.
