WebJul 17, 2024 · Everyone agrees on how to compute an Ed25519 signature given a secret scalar, which can be a uniform random 256-bit integer, and a PRF secret, which is a uniform random 256-bit string, but the scalar and PRF secret are stored or derived differently in different contexts. 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 •. hernia poultice review
