Struct VerifyingKey

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

Verifying key for RSASSA-PKCS1-v1_5 signatures as described in RFC8017 § 8.2.

Implementations

impl<D> VerifyingKey<D>

where D: Digest + AssociatedOid,

pub fn new(key: RsaPublicKey) -> Self

Create a new verifying key with a prefix for the digest D.

pub fn new_with_prefix(key: RsaPublicKey) -> Self

👎Deprecated since 0.9.0: use VerifyingKey::new instead

Create a new verifying key with a prefix for the digest D.

impl<D> VerifyingKey<D>

where D: Digest,

pub fn new_unprefixed(key: RsaPublicKey) -> Self

Create a new verifying key from an RSA public key with an empty prefix.

Note: unprefixed signatures are uncommon

In most cases you’ll want to use VerifyingKey::new instead.
