Struct SigningKey 

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

Signing key for producing RSASSA-PSS signatures as described in RFC8017 § 8.1.

Implementations

impl<D> SigningKey<D>

where D: Digest,

pub fn new(key: RsaPrivateKey) -> Self

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

Create a new RSASSA-PSS signing key with a salt of the given length.

pub fn random<R: CryptoRngCore + ?Sized>( rng: &mut R, bit_size: usize, ) -> Result<Self>

Generate a new random RSASSA-PSS signing key. Digest output size is used as a salt length.

pub fn random_with_salt_len<R: CryptoRngCore + ?Sized>( rng: &mut R, bit_size: usize, salt_len: usize, ) -> Result<Self>

Generate a new random RSASSA-PSS signing key with a salt of the given length.

pub fn salt_len(&self) -> usize

Return specified salt length for this key

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
