5 passwd - compute password hashes
18 The B<passwd> command computes the hashes of a list of passwords
19 passed on the command line, or the hash of a password typed at run-time.
20 Currently only the Unix standard algorithm B<crypt>
29 Use the B<crypt> algorithm (default).
33 Use the specified salt.
37 Don't output warnings when passwords are truncated.
41 In the output list, prepend the cleartext password and a TAB character
42 to each password hash.
48 B<openssl passwd -salt xx password> prints B<xxj31ZMTZzkVA>.
