Implementations

impl Pubkey

pub fn load_der(der: &[u8]) -> Result<Pubkey>

Load a DER encoded public key

pub fn load_pem(pem: &str) -> Result<Pubkey>

Load a PEM encoded public key

pub fn load_rsa(n: &MPI, e: &MPI) -> Result<Pubkey>

Load an RSA public key (n,e)

pub fn load_dh(p: &MPI, g: &MPI, y: &MPI) -> Result<Pubkey>

Load an DH public key (p,g,y)

pub fn load_dsa(p: &MPI, q: &MPI, g: &MPI, y: &MPI) -> Result<Pubkey>

Load an DSA public key (p,q,g,y)

pub fn load_elgamal(p: &MPI, g: &MPI, y: &MPI) -> Result<Pubkey>

Load an ElGamal public key (p,g,y)

pub fn load_ecdsa(pub_x: &MPI, pub_y: &MPI, curve_name: &str) -> Result<Pubkey>

Load an ECDSA public key (x,y) for the specified curve

pub fn load_ecdh(pub_x: &MPI, pub_y: &MPI, curve_name: &str) -> Result<Pubkey>

Load an ECDH public key (x,y) for the specified curve

pub fn load_ed25519(key: &[u8]) -> Result<Pubkey>

Load an Ed25519 public key

pub fn load_x25519(key: &[u8]) -> Result<Pubkey>

Load an X25519 key

pub fn load_ml_kem(key: &[u8]) -> Result<Pubkey>

Load a ML-KEM public key from the raw byte encoding

The exact type can be determined by the length and does not need to be specified

This requires botan_ffi_20250506, otherwise a not implemented error is returned

pub fn estimated_strength(&self) -> Result<usize>

Return estimated bit strength of this key

pub fn check_key(&self, rng: &mut RandomNumberGenerator) -> Result<bool>

Check key for problems

pub fn fingerprint(&self, hash: &str) -> Result<Vec<u8>>

Return hash of the public key data

pub fn der_encode(&self) -> Result<Vec<u8>>

DER encode this public key

pub fn pem_encode(&self) -> Result<String>

PEM encode this public key

pub fn ec_public_point(&self) -> Result<Vec<u8>>

Return the encoded elliptic curve point associated with this key

Only valid for EC based keys

This requires botan_ffi_20230403, otherwise a not implemented error is returned

pub fn algo_name(&self) -> Result<String>

Return the name of the algorithm

pub fn get_field(&self, which: &str) -> Result<MPI>

Get a value for the public key The which parameter selects a field which is algorithm specific

pub fn raw_bytes(&self) -> Result<Vec<u8>>

Return the raw byte encoding of this key

This requires botan_ffi_20250506, otherwise a not implemented error is returned

pub fn get_ed25519_key(&self) -> Result<Vec<u8>>

Return the 32-byte Ed25519 public key

pub fn get_x25519_key(&self) -> Result<Vec<u8>>

Get the X25519 public key

pub fn encrypt( &self, message: &[u8], padding: &str, rng: &mut RandomNumberGenerator, ) -> Result<Vec<u8>>

Encrypt a message using the specified padding method

pub fn verify( &self, message: &[u8], signature: &[u8], padding: &str, ) -> Result<bool>

Verify a message that was signed using the specified padding method
