Ed25519 key material.

A thin, domain-scoped wrapper over kryptos/eddsa fixed to the Ed25519 curve, so callers never need to import kryptos directly or think about kryptos/eddsa.Curve.

Types

KeyError

pub type KeyError {
  InvalidPem

  InvalidKeyBytes
}

Constructors

Values

generate

</>

pub fn generate() -> #(eddsa.PrivateKey, eddsa.PublicKey)

Generates a new Ed25519 key pair.

key_pair_from_base64

</>

pub fn key_pair_from_base64(
  seed: String,
) -> Result(#(eddsa.PrivateKey, eddsa.PublicKey), KeyError)

Loads a private key (and its derived public key) from a base64-encoded 32-byte seed — the format Open Payments-style ecosystems commonly use to distribute raw Ed25519 keys.

key_pair_from_pem

</>

pub fn key_pair_from_pem(
  pem: String,
) -> Result(#(eddsa.PrivateKey, eddsa.PublicKey), KeyError)

Loads a private key (and its derived public key) from a PKCS#8 PEM.

private_key_to_pem

</>

pub fn private_key_to_pem(
  key: eddsa.PrivateKey,
) -> Result(String, KeyError)

Exports a private key as a PKCS#8 PEM.

public_key_from_base64

</>

pub fn public_key_from_base64(
  bytes: String,
) -> Result(eddsa.PublicKey, KeyError)

Loads a public key from a base64-encoded 32-byte point.

public_key_from_pem

</>

pub fn public_key_from_pem(
  pem: String,
) -> Result(eddsa.PublicKey, KeyError)

Loads a public key from an SPKI PEM.

public_key_to_pem

</>

pub fn public_key_to_pem(
  key: eddsa.PublicKey,
) -> Result(String, KeyError)

Exports a public key as an SPKI PEM.
