Implementations

impl<D> SigningKey<D>

where D: Digest + AssociatedOid,

pub fn new(key: RsaPrivateKey) -> Self

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

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

Generate a new signing key with a prefix for the digest D.

pub fn new_with_prefix(key: RsaPrivateKey) -> Self

👎Deprecated since 0.9.0: use SigningKey::new instead

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

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

👎Deprecated since 0.9.0: use SigningKey::random instead

Generate a new signing key with a prefix for the digest D.

impl<D> SigningKey<D>

where D: Digest,

pub fn new_unprefixed(key: RsaPrivateKey) -> Self

Create a new signing key from the give RSA private key with an empty prefix.

Note: unprefixed signatures are uncommon

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

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

Generate a new signing key with an empty prefix.
