Module dryoc::classic::crypto_sign_ed25519
source · Expand description
Ed25519 to Curve25519 conversion
This module implements libsodium’s Ed25519 to Curve25519 conversion functions. You can use these functions when you want to sign messages with the same keys used to encrypt messages (i.e., using a public-key box).
Generally speaking, you should avoid signing and encrypting with the same keypair. Additionally, an encrypted box doesn’t need to be separately signed as it already includes a message authentication code.
Functions
Converts an Ed25519 public key
ed25519_public_key into an X25519 public
key, placing the result into x25519_public_key upon success.Converts an Ed25519 secret key
ed25519_secret_key into an X25519 secret
key key, placing the result into x25519_secret_key.
