Struct Ed25519PublicKey

pub struct Ed25519PublicKey(/* private fields */);

An Ed25519 public key for verifying digital signatures.

Ed25519 public keys are used to verify signatures created with the corresponding private key. The Ed25519 signature system provides:

• Fast signature verification
• Small public keys (32 bytes)
• High security with resistance to various attacks

This implementation allows:

• Creating Ed25519 public keys from raw data
• Verifying signatures against messages
• Converting between various formats

Implementations

impl Ed25519PublicKey

pub const fn from_data(data: [u8; 32]) -> Self

Restores an Ed25519 public key from an array of bytes.

pub fn from_data_ref(data: impl AsRef<[u8]>) -> Result<Self>

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

Returns the Ed25519 public key as an array of bytes.

pub fn from_hex(hex: impl AsRef<str>) -> Result<Self>

impl Ed25519PublicKey

pub fn verify(&self, signature: &[u8; 64], message: impl AsRef<[u8]>) -> bool

Verifies the given Ed25519 signature for the given message using this Ed25519 public key.
