Struct 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.

pub fn new_with_auto_salt_len(key: RsaPublicKey) -> Self

Create a new RSASSA-PSS verifying key. Attempts to automatically detect the salt length.

pub fn salt_len(&self) -> Option<usize>

Return specified salt length for this key
