CLI utility for node-argon2.
Want to use it in your Javascript application? Instead check node-argon2.
Check requirements for node-argon2 prior to installing this.
node-argon2-cli works only and is tested against Node >=4.0.0.
Run argon2 -h for a quick help on usage and arguments:
$ argon2 -h
usage: argon2 salt [-d] [-t iterations] [-m memory] [-p parallelism]
Password is read from stdin
Positional arguments:
salt
Optional arguments:
-h, --help Show this help message and exit.
-d, --argon2d Use Argon2d instead of Argon2i (default: false)
-m N Sets the memory usage to 2^N KiB (default: 12)
-t N Sets the number of iterations to N (default: 3)
-p N Sets parallelism to N threads (default: 1)
-q Do not output timing information (default: false)To hash a password:
$ echo -n "password" | argon2
Type: Argon2i
Iterations: 3
Memory: 4096 KiB
Parallelism: 1
Encoded: $argon2i$m=4096,t=3,p=1$cZVXCGXwTBcocU4aOhjMkQ$HSAo4K9SAYUTdl/GWluOJNthqmTk1YmzNQHpZPp9sn8
0.010 seconds
Verification okBy default, the output is verbose. You can output the hash only with -q:
$ echo -n "password" | argon2 -q
$argon2i$m=4096,t=3,p=1$BFUGTNcvBjSAtYklcJFhZQ$lQsmd5Fjef2/4UTFlgXLNb8D7iFFgt0PvYVsgn+6lLsYou can choose between Argon2i and Argon2d by using the --argon2d (-d) flag:
$ echo -n "password" | argon2 -d -q
$argon2d$m=4096,t=3,p=1$x7OyWwTq0HryCyqahgZcMA$25HOolJnT/uBw4kK2rKZ4IanAA8eAYqUcg+9o0lIj2gYou can provide your own salt as the positional argument. It is highly recommended to use the generated salt instead of a hardcoded salt, though:
$ echo -n "password" | argon2 somesalt -q
$argon2i$m=4096,t=3,p=1$c29tZXNhbHQ$vpOd0mbc3AzXEHMgcTb1CrZt5XuoRQuz1kQtGBv7ejkYou can also modify time, memory and parallelism constraints with -t, -m and
-p respectively, followed by a valid number:
$ echo -n "password" | ./cli.js -t 2 -m 16 -p 4
Type: Argon2i
Iterations: 2
Memory: 65536 KiB
Parallelism: 4
Encoded: $argon2i$m=65536,t=2,p=4$/tH9944/9OdsUauNaTVgfw$Glxg3SkUfkLETBHxaq1GamsaTBiYdBNRppL2Mqm7hqo

Verification okAll arguments are optional, and it's not possible to pass your password as
argument for safety purposes (consider you should never write a password with
echo).
