Struct SecretKey 

pub struct SecretKey { /* private fields */ }

Available on crate feature rsa only.

SecretKey contains a 2048-bit RSA private key usable for signing, with SHA256 as the underlying hash algorithm. Whilst RSA could also be used for encryption, that is not exposed on the API as it’s not required by the project.

Implementations

impl SecretKey

pub fn generate() -> SecretKey

generate creates a new, random private key.

pub fn from_bytes(bytes: &[u8; 520]) -> Result<Self, Error>

from_bytes parses a 520-byte array into a private key.

Format: p (128 bytes) || q (128 bytes) || d (256 bytes) || e (8 bytes), all in big-endian.

pub fn from_der(der: &[u8]) -> Result<Self, Box<dyn Error>>

from_der parses a DER buffer into a private key.

pub fn from_pem(pem_str: &str) -> Result<Self, Box<dyn Error>>

from_pem parses a PEM string into a private key.

pub fn to_bytes(&self) -> [u8; 520]

to_bytes serializes a private key into a 520-byte array.

Format: p (128 bytes) || q (128 bytes) || d (256 bytes) || e (8 bytes), all in big-endian.

pub fn to_der(&self) -> Vec<u8>

to_der serializes a private key into a DER buffer.

pub fn to_pem(&self) -> String

to_pem serializes a private key into a PEM string.

pub fn public_key(&self) -> PublicKey

public_key retrieves the public counterpart of the secret key.

pub fn fingerprint(&self) -> Fingerprint

fingerprint returns a 256bit unique identified for this key. For RSA, that is the SHA256 hash of the raw (le modulus || le exponent) public key.

pub fn sign(&self, message: &[u8]) -> Signature

sign creates a digital signature of the message.

Trait Implementations

impl Clone for SecretKey

fn clone(&self) -> SecretKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
