Struct Pss 

pub struct Pss<D> {
    pub blinded: bool,
    pub digest: D,
    pub salt_len: Option<usize>,
}

Digital signatures using PSS padding.

Fields

blinded: bool

Create blinded signatures.

digest: D

Digest type to use.

salt_len: Option<usize>

Salt length. Required for signing, optional for verifying.

Implementations

impl<D> Pss<D>

where D: Digest,

pub fn new() -> Self

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

pub fn new_with_salt(len: usize) -> Self

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

pub fn new_blinded() -> Self

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(len: usize) -> Self

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

Trait Implementations

impl<D> Debug for Pss<D>

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

Formats the value using the given formatter.

impl<D> Default for Pss<D>

where D: Digest,

fn default() -> Self

Returns the “default value” for a type.

impl<D> SignatureScheme for Pss<D>

where D: Digest + FixedOutputReset,

Available on crate feature alloc only.

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

Available on crate feature private-key only.

Sign the given digest.

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

where T: UnsignedModularInt, K: PublicKeyParts<T>,

Verify a signed message.
