Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator
and subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for
the purpose of contributing to a commons of creative, cultural and
scientific works ("Commons") that the public can reliably and without fear
of later claims of infringement build upon, modify, incorporate in other
works, reuse and redistribute as freely as possible in any form whatsoever
and for any purposes, including without limitation commercial purposes.
These owners may contribute to the Commons to promote the ideal of a free
culture and the further production of creative, cultural and scientific
works, or to gain reputation or greater distribution for their Work in
part through the use and efforts of others.
For these and/or other purposes and motivations, and without any
expectation of additional consideration or compensation, the person
associating CC0 with a Work (the "Affirmer"), to the extent that he or she
is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its
terms, with knowledge of his or her Copyright and Related Rights in the
Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not
limited to, the following:
i. the right to reproduce, adapt, distribute, perform, display,
communicate, and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or
likeness depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data
in a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation
thereof, including any amended or successor version of such
directive); and
vii. other similar, equivalent or corresponding rights throughout the
world based on applicable law or treaty, and any national
implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention
of, applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright and Related Rights and associated claims and causes
of action, whether now known or unknown (including existing as well as
future claims and causes of action), in the Work (i) in all territories
worldwide, (ii) for the maximum duration provided by applicable law or
treaty (including future time extensions), (iii) in any current or future
medium and for any number of copies, and (iv) for any purpose whatsoever,
including without limitation commercial, advertising or promotional
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
member of the public at large and to the detriment of Affirmer's heirs and
successors, fully intending that such Waiver shall not be subject to
revocation, rescission, cancellation, termination, or any other legal or
equitable action to disrupt the quiet enjoyment of the Work by the public
as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason
be judged legally invalid or ineffective under applicable law, then the
Waiver shall be preserved to the maximum extent permitted taking into
account Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver is so judged Affirmer hereby grants to each affected
person a royalty-free, non transferable, non sublicensable, non exclusive,
irrevocable and unconditional license to exercise Affirmer's Copyright and
Related Rights in the Work (i) in all territories worldwide, (ii) for the
maximum duration provided by applicable law or treaty (including future
time extensions), (iii) in any current or future medium and for any number
of copies, and (iv) for any purpose whatsoever, including without
limitation commercial, advertising or promotional purposes (the
"License"). The License shall be deemed effective as of the date CC0 was
applied by Affirmer to the Work. Should any part of the License for any
reason be judged legally invalid or ineffective under applicable law, such
partial invalidity or ineffectiveness shall not invalidate the remainder
of the License, and in such case Affirmer hereby affirms that he or she
will not (i) exercise any of his or her remaining Copyright and Related
Rights in the Work or (ii) assert any associated claims and causes of
action with respect to the Work, in either case contrary to Affirmer's
express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or
warranties of any kind concerning the Work, express, implied,
statutory or otherwise, including without limitation warranties of
title, merchantability, fitness for a particular purpose, non
infringement, or the absence of latent or other defects, accuracy, or
the present or absence of errors, whether or not discoverable, all to
the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without
limitation any person's Copyright and Related Rights in the Work.
Further, Affirmer disclaims responsibility for obtaining any necessary
consents, permissions or other rights required for any use of the
Work.

# Argon2
[![Build Status](https://travis-ci.org/P-H-C/phc-winner-argon2.svg?branch=master)](https://travis-ci.org/P-H-C/phc-winner-argon2)
[![Build status](https://ci.appveyor.com/api/projects/status/8nfwuwq55sgfkele?svg=true)](https://ci.appveyor.com/project/P-H-C/phc-winner-argon2)
[![codecov.io](https://codecov.io/github/P-H-C/phc-winner-argon2/coverage.svg?branch=master)](https://codecov.io/github/P-H-C/phc-winner-argon2?branch=master)
This is the reference C implementation of Argon2, the password-hashing
function that won the [Password Hashing Competition
(PHC)](https://password-hashing.net).
Argon2 is a password-hashing function that summarizes the state of the
art in the design of memory-hard functions and can be used to hash
passwords for credential storage, key derivation, or other applications.
It has a simple design aimed at the highest memory filling rate and
effective use of multiple computing units, while still providing defense
against tradeoff attacks (by exploiting the cache and memory organization
of the recent processors).
Argon2 has three variants: Argon2i, Argon2d, and Argon2id. Argon2d is faster
and uses data-depending memory access, which makes it highly resistant
against GPU cracking attacks and suitable for applications with no threats
from side-channel timing attacks (eg. cryptocurrencies). Argon2i instead
uses data-independent memory access, which is preferred for password
hashing and password-based key derivation, but it is slower as it makes
more passes over the memory to protect from tradeoff attacks. Argon2id is a
hybrid of Argon2i and Argon2d, using a combination of data-depending and
data-independent memory accesses, which gives some of Argon2i's resistance to
side-channel cache timing attacks and much of Argon2d's resistance to GPU
cracking attacks.
Argon2i, Argon2d, and Argon2id are parametrized by:
* A **time** cost, which defines the amount of computation realized and
therefore the execution time, given in number of iterations
* A **memory** cost, which defines the memory usage, given in kibibytes
* A **parallelism** degree, which defines the number of parallel threads
The [Argon2 document](argon2-specs.pdf) gives detailed specs and design
rationale.
Please report bugs as issues on this repository.
## Usage
`make` builds the executable `argon2`, the static library `libargon2.a`,
and the shared library `libargon2.so` (or on macOS, the dynamic library
`libargon2.dylib` -- make sure to specify the installation prefix when
you compile: `make PREFIX=/usr`). Make sure to run `make test` to verify
that your build produces valid results. `sudo make install PREFIX=/usr`
installs it to your system.
### Command-line utility
`argon2` is a command-line utility to test specific Argon2 instances
on your system. To show usage instructions, run
`./argon2 -h` as
```
Usage: ./argon2 [-h] salt [-i|-d|-id] [-t iterations] [-m memory] [-p parallelism] [-l hash length] [-e|-r] [-v (10|13)]
Password is read from stdin
Parameters:
salt The salt to use, at least 8 characters
-i Use Argon2i (this is the default)
-d Use Argon2d instead of Argon2i
-id Use Argon2id instead of Argon2i
-t N Sets the number of iterations to N (default = 3)
-m N Sets the memory usage of 2^N KiB (default 12)
-p N Sets parallelism to N threads (default 1)
-l N Sets hash output length to N bytes (default 32)
-e Output only encoded hash
-r Output only the raw bytes of the hash
-v (10|13) Argon2 version (defaults to the most recent version, currently 13)
-h Print argon2 usage
```
For example, to hash "password" using "somesalt" as a salt and doing 2
iterations, consuming 64 MiB, using four parallel threads and an output hash
of 24 bytes
```
$ echo -n "password" | ./argon2 somesalt -t 2 -m 16 -p 4 -l 24
Type: Argon2i
Iterations: 2
Memory: 65536 KiB
Parallelism: 4
Hash: 45d7ac72e76f242b20b77b9bf9bf9d5915894e669a24e6c6
Encoded: $argon2i$v=19$m=65536,t=2,p=4$c29tZXNhbHQ$RdescudvJCsgt3ub+b+dWRWJTmaaJObG
0.188 seconds
Verification ok
```
### Library
`libargon2` provides an API to both low-level and high-level functions
for using Argon2.
The example program below hashes the string "password" with Argon2i
using the high-level API and then using the low-level API. While the
high-level API takes the three cost parameters (time, memory, and
parallelism), the password input buffer, the salt input buffer, and the
output buffers, the low-level API takes in these and additional parameters
, as defined in [`include/argon2.h`](include/argon2.h).
There are many additional parameters, but we will highlight three of them here.
1. The `secret` parameter, which is used for [keyed hashing](
https://en.wikipedia.org/wiki/Hash-based_message_authentication_code).
This allows a secret key to be input at hashing time (from some external
location) and be folded into the value of the hash. This means that even if
your salts and hashes are compromised, an attacker cannot brute-force to find
the password without the key.
2. The `ad` parameter, which is used to fold any additional data into the hash
value. Functionally, this behaves almost exactly like the `secret` or `salt`
parameters; the `ad` parameter is folding into the value of the hash.
However, this parameter is used for different data. The `salt` should be a
random string stored alongside your password. The `secret` should be a random
key only usable at hashing time. The `ad` is for any other data.
3. The `flags` parameter, which determines which memory should be securely
erased. This is useful if you want to securely delete the `pwd` or `secret`
fields right after they are used. To do this set `flags` to either
`ARGON2_FLAG_CLEAR_PASSWORD` or `ARGON2_FLAG_CLEAR_SECRET`. To change how
internal memory is cleared, change the global flag
`FLAG_clear_internal_memory` (defaults to clearing internal memory).
Here the time cost `t_cost` is set to 2 iterations, the
memory cost `m_cost` is set to 2<sup>16</sup> kibibytes (64 mebibytes),
and parallelism is set to 1 (single-thread).
Compile for example as `gcc test.c libargon2.a -Isrc -o test`, if the program
below is named `test.c` and placed in the project's root directory.
```c
#include "argon2.h"
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define HASHLEN 32
#define SALTLEN 16
#define PWD "password"
int main(void)
{
uint8_t hash1[HASHLEN];
uint8_t hash2[HASHLEN];
uint8_t salt[SALTLEN];
memset( salt, 0x00, SALTLEN );
uint8_t *pwd = (uint8_t *)strdup(PWD);

printf( "%02x", hash2[i] );
}

}
else printf("ok\n");
return 0;
}
```
To use Argon2d instead of Argon2i call `argon2d_hash_raw` instead of
`argon2i_hash_raw` using the high-level API, and `argon2d` instead of
`argon2i` using the low-level API. Similarly for Argon2id, call `argon2id_hash_raw`
and `argon2id`.
To produce the crypt-like encoding rather than the raw hash, call
`argon2i_hash_encoded` for Argon2i, `argon2d_hash_encoded` for Argon2d, and
`argon2id_hash_encoded` for Argon2id
See [`include/argon2.h`](include/argon2.h) for API details.
*Note: in this example the salt is set to the all-`0x00` string for the
sake of simplicity, but in your application you should use a random salt.*
### Benchmarks
`make bench` creates the executable `bench`, which measures the execution
time of various Argon2 instances:
```
$ ./bench
Argon2d 1 iterations 1 MiB 1 threads: 5.91 cpb 5.91 Mcycles
Argon2i 1 iterations 1 MiB 1 threads: 4.64 cpb 4.64 Mcycles

There are two sets of test suites. One is a low level test for the hash
function, the other tests the higher level API. Both of these are built and
executed by running:
`make test`

.TH ARGON2 "1" "April 2016" "argon2 " "User Commands"
.SH NAME
argon2 \- generate argon2 hashes
.SH SYNOPSIS
.B argon2 salt
.RB [ OPTIONS ]
.SH DESCRIPTION
Generate Argon2 hashes from the command line.
The supplied salt (the first argument to the command) must be at least
8 octets in length, and the password is supplied on standard input.
By default, this uses Argon2i variant (where memory access is
independent of secret data) which is the preferred one for password
hashing and password-based key derivation.
.SH OPTIONS
.TP
.B \-h
Display tool usage
.TP
.B \-d
Use Argon2d instead of Argon2i (Argon2i is the default)
.TP
.B \-id
Use Argon2id instead of Argon2i (Argon2i is the default)
.TP
.BI \-t " N"
Sets the number of iterations to N (default = 3)
.TP
.BI \-m " N"
Sets the memory usage of 2^N KiB (default = 12)
.TP
.BI \-p " N"
Sets parallelism to N threads (default = 1)
.TP
.BI \-l " N"
Sets hash output length to N bytes (default = 32)
.TP
.B \-e
Output only encoded hash
.TP
.B \-r
Output only the raw bytes of the hash
.TP
.B \-v (10|13)
Argon2 version (defaults to the most recent version, currently 13)

* Example code for a decoder and encoder of "hash strings", with Argon2

*
* This code comprises three sections:
*
* -- The first section contains generic Base64 encoding and decoding
* functions. It is conceptually applicable to any hash function
* implementation that uses Base64 to encode and decode parameters,
* salts and outputs. It could be made into a library, provided that

*

* the parameters, salts and outputs. It does not compute the hash
* itself.
*
* The code was originally written by Thomas Pornin <pornin@bolet.org>,
* to whom comments and remarks may be sent. It is released under what
