Wishlist: Encryption for ed25519/X25519

FGasper opened this issue · comments

It would be useful to be able to encrypt a string via ed25519/X25519. Could libtomcrypt’s ECDSA encryption algorithm apply also to ed25519/X25519?

Thank you!

commented

The version from the develop branch provides this feature.

@sjaeckel I am afraid @FGasper meant ec25519 analogy to ECDH-based Encrypt and Decrypt as described here https://github.com/libtom/libtomcrypt/blob/develop/doc/crypt.tex#L5666 = ecc_encrypt_key + ecc_decrypt_key.

May be we should consider something like https://libsodium.gitbook.io/doc/public-key_cryptography/authenticated_encryption

I'm not sure, so let's wait for @FGasper's opinion
