The passwd command computes the hash of a password typed at
run-time or the hash of each password in a list. The password list is
taken from the named file for option -in file, from stdin for
option -stdin, or from the command line, or from the terminal otherwise.
The Unix standard algorithm crypt and the MD5-based BSD password
algorithm 1 and its Apache variant apr1 are available.
OPTIONS
-crypt
Use the crypt algorithm (default).
-1
Use the MD5 based BSD password algorithm 1.
-apr1
Use the apr1 algorithm (Apache variant of the BSD algorithm).
-saltstring
Use the specified salt.
When reading a password from the terminal, this implies -noverify.
-infile
Read passwords from file.
-stdin
Read passwords from stdin.
-noverify
Don't verify when reading a password from the terminal.
-quiet
Don't output warnings when passwords given at the command line are truncated.
-table
In the output list, prepend the cleartext password and a TAB character
to each password hash.
