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 -infile, 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.
Use the crypt algorithm (default).
-1 Use the MD5 based BSD password algorithm 1.
Use the apr1 algorithm (Apache variant of the BSD algorithm).
Use the specified salt. When reading a password from the terminal, this implies -noverify.
Read passwords from file.
Read passwords from stdin.
Don't verify when reading a password from the terminal.
Don't output warnings when passwords given at the command line are truncated.
In the output list, prepend the cleartext password and a TAB character to each password hash.
