curve25519_keypair() -> #{atom() => binary()}
curve25519_keypair/0 creates a new Public/Secret keypair.
Generates and returns a new key pair for the Curve 25519 encryption scheme. The return value is a map in order to avoid using the public key as a secret key and vice versa.curve25519_public_key(SecretKey::binary()) -> binary()
curve25519_public_key/1 creates a public key from a given SecretKey.
curve25519_shared(SecretKey::binary(), PublicKey::binary()) -> binary()
curve25519_shared/2 creates a new shared secret from a given SecretKey and PublicKey.
scramble_block_16(Block::binary(), Key::binary()) -> binary()
scramble_block_16/2 scrambles (encrypt) a block under a given key The rules are that the block is 16 bytes and the key is 32 bytes. The block is scrambled by means of the (secret) key. This makes it impossible for an attacker to understand the original input for the scrambling. The intention of this method is to protect counters from leaking to the outside world, by scrambling them before they leave the system.
Scrambling is done by means of the TEA algorithm (Tiny Encryption Algorithm) It has known weaknesses and should probably not be used long-term going forward, but CurveCP currently uses it for nonce scrambling.Generated by EDoc
