Struct Pss 

pub struct Pss {
    pub blinded: bool,
    pub digest: Box<dyn DynDigest + Sync + Send>,
    pub salt_len: Option<usize>,
}

Digital signatures using PSS padding.

Fields

blinded: bool

Create blinded signatures.

digest: Box<dyn DynDigest + Sync + Send>

Digest type to use.

salt_len: Option<usize>

Salt length. Required for signing, optional for verifying.

Implementations

impl Pss

pub fn new<T>() -> Pss

where T: 'static + Digest + DynDigest + Send + Sync,

New PSS padding for the given digest. Digest output size is used as a salt length.

pub fn new_with_salt<T>(len: usize) -> Pss

where T: 'static + Digest + DynDigest + Send + Sync,

New PSS padding for the given digest with a salt value of the given length.

pub fn new_blinded<T>() -> Pss

where T: 'static + Digest + DynDigest + Send + Sync,

New PSS padding for blinded signatures (RSA-BSSA) for the given digest. Digest output size is used as a salt length.

pub fn new_blinded_with_salt<T>(len: usize) -> Pss

where T: 'static + Digest + DynDigest + Send + Sync,

New PSS padding for blinded signatures (RSA-BSSA) for the given digest with a salt value of the given length.

Trait Implementations

impl Debug for Pss

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl SignatureScheme for Pss

fn sign<Rng>( self, rng: Option<&mut Rng>, priv_key: &RsaPrivateKey, hashed: &[u8], ) -> Result<Vec<u8>, Error>

where Rng: TryCryptoRng + ?Sized,

Sign the given digest.

fn verify( self, pub_key: &RsaPublicKey, hashed: &[u8], sig: &[u8], ) -> Result<(), Error>

Verify a signed message.

impl SignatureScheme for Pss

fn new<D: Digest>() -> Self

Create a new instance of the signature scheme for the given digest algorithm.
