Public Struct Ed25519

Ed25519 (RFC 8032), EdDSA on Curve25519 with SHA-512: a private key is a 32-byte seed, a public key 32 bytes, and a signature 64 bytes, deterministic, so signing needs no random number.

Examples

Local privateKey = Ed25519.NewPrivateKey()
Local publicKey = Ed25519.PublicKeyOf(privateKey)
Local signature = Ed25519.Sign(privateKey, "release 1.0")
Expect(Ed25519.Verify(publicKey, "release 1.0", signature))
Expect(!Ed25519.Verify(publicKey, "release 1.1", signature))

Public Static Method NewPrivateKey(): UInt8[] static method #

A new random private key.
@PanicsAtCaller Public Static Method PublicKeyOf(privateKey: UInt8[]): UInt8[] static method #

privateKey's public key. Panics unless privateKey is 32 bytes.
@PanicsAtCaller Public Static Method Sign(privateKey: UInt8[], message: UInt8[]): UInt8[] static method #

message's signature with privateKey. Panics unless privateKey is 32 bytes.
@PanicsAtCaller Public Static Method Sign(privateKey: UInt8[], text: String): UInt8[] static method #

text's signature, by its UTF-8 bytes, with privateKey. Panics unless privateKey is 32 bytes.
Public Static Method Verify(publicKey: UInt8[], message: UInt8[], signature: UInt8[]): Bool static method #

Whether signature is publicKey's of message.
Public Static Method Verify(publicKey: UInt8[], text: String, signature: UInt8[]): Bool static method #

Whether signature is publicKey's of text's UTF-8 bytes.
