mkpasswd man page
mkpasswd — Overfeatured front end to crypt(3)
mkpasswd PASSWORD SALT
mkpasswd encrypts the given password with the crypt(3) libc function using the given salt.
- -S, --salt=STRING
Use the STRING as salt. It must not contain prefixes such as $1$.
- -R, --rounds=NUMBER
Use NUMBER rounds. This argument is ignored if the method chosen does not support variable rounds. For the OpenBSD Blowfish method this is the logarithm of the number of rounds. The behavior is undefined if this option is used without --method.
- -m, --method=TYPE
Compute the password using the TYPE method. If TYPE is help then the available methods are printed. If TYPE begins and end with $ characters then the string is passed to crypt_gensalt(3) as-is.
- -P, --password-fd=NUM
Read the password from file descriptor NUM instead of using getpass(3). If the file descriptor is not connected to a tty then no other message than the hashed password is printed on stdout.
- -s, --stdin
A list of options which will be evalued before the ones specified on the command line.
If the --stdin option is used, passwords containing some control characters may not be read correctly.
This programs suffers of a bad case of featuritis.
