Struct PublicKey 

pub struct PublicKey<C: Curve> { /* private fields */ }

An ECDSA public key over the given curve.

Implementations

impl<C: Curve> PublicKey<C>

pub fn from_x962_uncompressed(x962: &[u8]) -> Option<Self>

Parse a public key in uncompressed X9.62 format. (This is the common format for elliptic curve points beginning with an 0x04 byte.)

pub fn to_x962_uncompressed(&self) -> Buffer

Serialize this key as uncompressed X9.62 format.

pub fn from_x962_compressed(x962: &[u8]) -> Option<Self>

Parse a public key in compressed X9.62 point format.

pub fn to_x962_compressed(&self) -> Buffer

Serialize this key as compressed X9.62 format.

WARNING: compressed form is rarely used and is not as well supported as the uncompressed form.

pub fn from_der_subject_public_key_info(spki: &[u8]) -> Option<Self>

Parse a public key in SubjectPublicKeyInfo format. (This is found in, e.g., X.509 certificates.)

pub fn to_der_subject_public_key_info(&self) -> Buffer

Serialize this key in SubjectPublicKeyInfo format.

pub fn verify( &self, signed_msg: &[u8], signature: &[u8], ) -> Result<(), InvalidSignatureError>

Verify signature as a valid ASN.1-based signature of a digest of signed_msg with this public key. SHA-256 will be used to produce the digest if the curve of this public key is P-256. SHA-384 will be used to produce the digest if the curve of this public key is P-384.

pub fn verify_p1363( &self, signed_msg: &[u8], signature: &[u8], ) -> Result<(), InvalidSignatureError>

Verify signature as a valid P1363-based signature of a digest of signed_msg with this public key. SHA-256 will be used to produce the digest if the curve of this public key is P-256. SHA-384 will be used to produce the digest if the curve of this public key is P-384.
