LibSodium.Bindings

You will find below a list of the cryptographic bindings exposed:

	Purpose	Description	Algorithms	Module
	Secret-key Cryptography
	Authenticated Encryption	Encrypt a message and compute an authentication tag to make sure the message hasn't been tampered with.	Encryption: XSalsa20 stream cipher; Authentication: Poly1305 MAC	SecretBox
	Encrypted Streams	Encrypt a sequence of messages, or a single message split into an arbitrary number of chunks, using a secret key.	Initialisation: XChaCha20; Encryption: ChaCha20Poly1305-IETF	SecretStream
	Authentication	Compute an authentication tag for a message and a secret key, and verify that a given tag is valid for a given message and a key.	Authentication: HMAC-SHA512-256	CryptoAuth
	Public-key Cryptography
	Authenticated Encryption	Encrypt a confidential message with the recipient's public key, who can then decrypt it with their secret key.	Key exchange: X25519; Encryption: XSalsa20; Authentication: Poly1305	CryptoBox
	Public-key Signatures	Sign messages with a secret key, and distribute a public key, which anybody can use to verify that the signature appended to a message was issued by the creator of the public key.	Single-part signature: Ed25519; Multi-part signature: Ed25519ph	CryptoSign
	Sealed Boxes	Anonymously send messages to a recipient given their public key.	Key Exchange: X25519; Encryption: XSalsa20-Poly1305	SealedBoxes
	Hashing
	Generic Hashing	Computes a fixed-length fingerprint for an arbitrarily long message. Use this for file integrity checking and create unique identifiers to index arbitrarily long data. Do not use this API to hash passwords!	Hashing: BLAKE2b	GenericHashing
	Password Hashing	Hash passwords with high control on the computation parameters.	Hashing: Argon2id v1.3	PasswordHashing
	Short-input Hashing	Produce short hashes for your data, suitable to build Hash tables, probabilistic data structures or perform integrity checking in interactive protocols.	Hashing: SipHash-2-4	ShortHashing
	Cryptographic Keys
	Key Derivation	Derive secret keys from a single high-entropy key.	Key derivation: BLAKE2B	KeyDerivation
	Key Exchange	Securely compute a set of shared keys using your peer's public key and your own secret key.	Key generation: BLAKE2B-512	KeyExchange
	Other constructs
	SHA-2	Provide compatibility with existing applications for SHA-256 and SHA-512. You should prioritise GenericHashing and PasswordHashing for new developmentinstead.	SHA-256 and SHA-512	SHA2
	AEAD	Encrypt a message with a key and a nonce to keep it confidential, compute an authentication tag, and store optional, non-confidential data.	Encryption: XChaCha20 stream cipher; Authentication: Poly1305 MAC	AEAD
	XChaCha20	Implementation of the XChaCha20 stream cipher	XChaCha20 stream cipher	XChaCha20
	Scrypt	Unless you have specific reasons to use scrypt, you should instead consider the PasswordHashing module!	scrypt password hashing function	Scrypt
