32 This command computes the hash of a password typed at
33 run-time or the hash of each password in a list. The password list is
34 taken from the named file for option B<-in>, from stdin for
35 option B<-stdin>, or from the command line, or from the terminal otherwise.
36 The MD5-based BSD password algorithm B<-1>, its Apache variant B<-apr1>,
37 and its AIX variant are available.
45 Print out a usage message.
49 Use the MD5 based BSD password algorithm B<1> (default).
53 Use the B<apr1> algorithm (Apache variant of the BSD algorithm).
57 Use the B<AIX MD5> algorithm (AIX variant of the BSD algorithm).
63 Use the B<SHA256> / B<SHA512> based algorithms defined by Ulrich Drepper.
64 See L<https://www.akkadia.org/drepper/SHA-crypt.txt>.
66 =item B<-salt> I<string>
68 Use the specified salt.
69 When reading a password from the terminal, this implies B<-noverify>.
73 Read passwords from I<file>.
77 Read passwords from B<stdin>.
81 Don't verify when reading a password from the terminal.
85 Don't output warnings when passwords given at the command line are truncated.
89 In the output list, prepend the cleartext password and a TAB character
90 to each password hash.
94 When the B<-table> option is used, reverse the order of cleartext and hash.
