5// Package argon2 implements the key derivation function Argon2.
6// Argon2 was selected as the winner of the Password Hashing Competition and can
7// be used to derive cryptographic keys from passwords.
8//
9// For a detailed specification of Argon2 see [1].
10//
11// If you aren't sure which function you need, use Argon2id (IDKey) and
12// the parameter recommendations for your scenario.
13//
14// # Argon2i
15//
16// Argon2i (implemented by Key) is the side-channel resistant version of Argon2.
17// It uses data-independent memory access, which is preferred for password
18// hashing and password-based key derivation. Argon2i requires more passes over
19// memory than Argon2id to protect from trade-off attacks. The recommended
20// parameters (taken from [2]) for non-interactive operations are time=3 and to
21// use the maximum available memory.
22//
23// # Argon2id
24//
25// Argon2id (implemented by IDKey) is a hybrid version of Argon2 combining
26// Argon2i and Argon2d. It uses data-independent memory access for the first
27// half of the first iteration over the memory and data-dependent memory access
28// for the rest. Argon2id is side-channel resistant and provides better brute-
29// force cost savings due to time-memory tradeoffs than Argon2i. The recommended
30// parameters for non-interactive operations (taken from [2]) are time=1 and to
31// use the maximum available memory.

53// Key derives a key from the password, salt, and cost parameters using Argon2i
54// returning a byte slice of length keyLen that can be used as cryptographic
55// key. The CPU cost and parallelism degree must be greater than zero.
56//
57// For example, you can get a derived key for e.g. AES-256 (which needs a
58// 32-byte key) by doing:
59//

65//
