CryptoHChaCha20: a fast, stateless KDF based on the HChaCha20 The functions documented above use HKDF-SHA256, but the HKDF-SHA512 can be used simply by replacing the crypto_kdf_hkdf_sha256 prefix with crypto_kdf_hkdf_sha512. Rust bindings to the sodium library. In the libsodium library there is high-level key exchange functionality which produces a shared secret that is Libsodium builds their KDF on top of BLAKE2b: Besides the key, the function has two additional arguments: The subkey ID (a 8 byte value which is 0-padded and becomes the salt) and a ed25519 keys work fine, but curve25519 keys don't work, when trying to import the generated key GPG asks for a passphrase - despite not specifying a KDF. crypto_ kdf_ hkdf_ sha512_ keygen ⚠ crypto_ kdf_ hkdf_ sha512_ statebytes ⚠ crypto_ kdf_ keybytes ⚠ crypto_ kdf_ keygen ⚠ crypto_ kdf_ primitive ⚠ crypto_ kem_ ciphertextbytes ⚠ crypto_ kem_ dec Rust bindings to the sodium library.
