常用示例
Hash
echo -n "password" | argon2 [salt] -e
Example
echo -n "password" | argon2 [salt] -id -e
Example
echo -n "password" | argon2 [salt] -t [3] -m [16] -p [4] -e
Output raw bytes
echo -n "password" | argon2 [salt] -r
Pin to Argon2 version 13
echo -n "password" | argon2 [salt] -v [13] -e
说明
argon2 is a command-line tool for the Argon2 password hashing algorithm, winner of the Password Hashing Competition in 2015. It provides strong, memory-hard password hashing resistant to GPU and ASIC attacks. The tool supports Argon2d (data-dependent), Argon2i (data-independent), and Argon2id (hybrid) variants.
参数
- -d
- Use Argon2d (data-dependent, GPU-resistant). Default is Argon2i.
- -i
- Use Argon2i (data-independent, side-channel resistant). This is the default if no variant flag is given.
- -id
- Use Argon2id (hybrid; recommended for password hashing).
- -t _N_
- Time cost (iterations). Default: _3_.
- -m _N_
- Memory cost expressed as 2^_N_ KiB. Default: _12_ (4 MiB).
- -p _N_
- Parallelism (threads). Default: _1_.
- -l _N_
- Output hash length in bytes. Default: _32_.
- -e
- Print only the encoded hash (PHC string format).
- -r
- Print only the raw hash bytes.
- -v _10|13_
- Argon2 algorithm version. Default: _13_.
- -h
- Display tool usage and exit.
