pub struct PublicKey(_);
Expand description

An Ed25519 public key.

Implementations§

§

impl PublicKey

pub fn verify(&self, msg: &[u8], sig: &[u8]) -> bool

Verify the Ed25519 signature on a message using the public key.

pub fn encode(&self) -> [u8; 32]

👎Deprecated since 0.2.0: Renamed to PublicKey::to_bytes to reflect actual behaviour.

Encode the public key into a byte array in compressed form, i.e. where one coordinate is represented by a single bit.

pub fn to_bytes(&self) -> [u8; 32]

Convert the public key to a byte array in compressed form, i.e. where one coordinate is represented by a single bit.

pub fn decode(k: &[u8]) -> Result<PublicKey, DecodingError>

👎Deprecated since 0.2.0: This method name does not follow Rust naming conventions, use PublicKey::try_from_bytes instead.

Decode a public key from a byte array as produced by to_bytes.

pub fn try_from_bytes(k: &[u8]) -> Result<PublicKey, DecodingError>

Try to parse a public key from a byte array containing the actual key as produced by to_bytes.
