WebDescription ¶. sodium_crypto_sign_ed25519_pk_to_curve25519 ( string $public_key ): string. Given an Ed25519 public key, calculate the birationally equivalent X25519 public key. WebYes, this will work. Specifically: Convert the recipient's Ed25519 PK to a Curve25519 PK. Use the result of step 1 in a standard DH key exchange with your own (preferably freshly generated) Curve25519 keypair. Send the recipient the encrypted message plus the PK from step 2. kodablah •.
