Struct PublicKey 

pub struct PublicKey { /* private fields */ }

Available on crate feature rsa only.

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

Implementations

impl PublicKey

pub fn from_bytes(bytes: &[u8; 264]) -> Result<Self, Error>

from_bytes parses a 264-byte array into a public key.

Format: n (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 public key.

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

from_pem parses a PEM string into a public key.

pub fn to_bytes(&self) -> [u8; 264]

to_bytes serializes a public key into a 264-byte array.

Format: n (256 bytes) || e (8 bytes), all in big-endian.

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

to_der serializes a public key into a DER buffer.

pub fn to_pem(&self) -> String

to_pem serializes a public key into a PEM string.

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 verify(&self, message: &[u8], signature: &Signature) -> Result<(), Error>

verify verifies a digital signature.

pub fn verify_hash( &self, hash: &[u8], signature: &Signature, ) -> Result<(), Error>

verify_hash verifies a digital signature on an already hashed message.
