You can use Authelia binary or docker image to generate the hash of any password. The
|
||||
hash-password command has many tunable options, you can view them with the

`authelia hash-password --help` command. For example if you wanted to improve the entropy
|
||||
you could generate a 16 byte salt and provide it with the `--salt` flag.
|
||||
Example: `authelia hash-password --salt abcdefghijklhijl`. For argon2id the salt must
|
||||
always be valid for base64 decoding (characters a through z, A through Z, 0 through 9, and +/).

## Password Hash Function
|
||||
```
|
||||
Hash a password to be used in file-based users database. Default algorithm is argon2id.
|
||||
|
||||
The only supported hash function is salted sha512 determined by the prefix `$6$` as described
|
||||
in this [wiki](https://en.wikipedia.org/wiki/Crypt_(C)) page.
|
||||
Usage:
|
||||
authelia hash-password [password] [flags]
|
||||
|
||||
Although not the best hash function, Salted SHA512 is a decent algorithm given the number of rounds is big
|
||||
enough. It's not the best because the difficulty to crack the hash does not on the performance of the machine.
|
||||
The best algorithm, [Argon2](https://en.wikipedia.org/wiki/Argon2) does though. It won the
|
||||
[Password Hashing Competition](https://en.wikipedia.org/wiki/Password_Hashing_Competition) in 2015 and is now
|
||||
considered the best hashing function. There is an open [issue](https://github.com/authelia/authelia/issues/577)
|
||||
to add support for this hashing function.
|
||||
Flags:
|
||||
-h, --help help for hash-password
|
||||
-i, --iterations int set the number of hashing iterations (default 1)
|
||||
-k, --key-length int [argon2id] set the key length param (default 32)
|
||||
-m, --memory int [argon2id] set the amount of memory param (in MB) (default 1024)
|
||||
-p, --parallelism int [argon2id] set the parallelism param (default 8)
|
||||
-s, --salt string set the salt string
|
||||
-l, --salt-length int set the auto-generated salt length (default 16)
|
||||
-z, --sha512 use sha512 as the algorithm (defaults iterations to 50000, change with -i)
|
||||
```
|
||||
|
||||
## Password hash algorithm
|
||||
The default hash algorithm is salted Argon2id version 19. Argon2id is currently considered
|
||||
the best hashing algorithm, and in 2015 won the
|
||||
[Password Hashing Competition](https://en.wikipedia.org/wiki/Password_Hashing_Competition).
|
||||
It benefits from customizable parameters allowing the cost of computing a hash to scale
|
||||
into the future which makes it harder to brute-force. Argon2id was implemented due to community
|
||||
feedback as you can see in this closed [issue](https://github.com/authelia/authelia/issues/577).
|
||||
|
||||
Additionally SHA512 is supported for backwards compatibility and user choice. While it's a reasonable
|
||||
hash function given high enough iterations, as hardware gets better it has a higher chance of being
|
||||
brute-forced.
|
||||
|
||||
Hashes are identifiable as argon2id or SHA512 by their prefix of either `$argon2id$` and `$6$`
|
||||
respectively, as described in this [wiki page](https://en.wikipedia.org/wiki/Crypt_(C)).
|
||||
|
||||
### Password hash algorithm tuning
|
||||
|
||||
All algorithm tuning is supported for Argon2id. The only configuration variables that affect
|
||||
SHA512 are iterations and salt length. The configuration variables are unique to the file
|
||||
authentication provider, thus they all exist in a key under the file authentication configuration
|
||||
key called `password_hashing`. We have set what are considered as sane and recommended defaults
|
||||
to cater for a reasonable system, if you're unsure about which settings to tune, please see the
|
||||
parameters above, or for a more in depth understanding see the referenced documentation.

## Protections against password cracking (File authentication provider)
|
||||
|
||||
Authelia implements a variety of measures to prevent an attacker cracking passwords if they
|
||||
somehow obtain the file used by the file authentication provider, this is unrelated to LDAP auth.
|
||||
|
||||
First and foremost Authelia only uses very secure hashing algorithms with sane and secure defaults.
|
||||
The first and default hashing algorithm we use is Argon2id which is currently considered
|
||||
the most secure hashing algorithm. We also support SHA512, which previously was the default.
|
||||
|
||||
Secondly Authelia uses salting with all hashing algorithms. These salts are generated with a random
|
||||
string generator, which is seeded every time it's used by a cryptographically secure 1024bit prime number.
|
||||
This ensures that even if an attacker obtains the file, each password has to be brute forced individually.
|
||||
|
||||
Lastly Authelia's implementation of Argon2id is highly tunable. You can tune the key length, salt
|
||||
used, iterations (time), paralellism, and memory usage. To read more about this please read how to
|
||||
[configure](../configuration/authentication/file.md) file authentication.
