33 This command computes the hash of a password typed at
34 run-time or the hash of each password in a list. The password list is
35 taken from the named file for option B<-in>, from stdin for
36 option B<-stdin>, or from the command line, or from the terminal otherwise.
37 The Unix standard algorithm B<-crypt> and the MD5-based BSD password
38 algorithm B<-1>, its Apache variant B<-apr1>, and its AIX variant are
47 Print out a usage message.
51 Use the B<crypt> algorithm (default).
55 Use the MD5 based BSD password algorithm B<1>.
59 Use the B<apr1> algorithm (Apache variant of the BSD algorithm).
63 Use the B<AIX MD5> algorithm (AIX variant of the BSD algorithm).
69 Use the B<SHA256> / B<SHA512> based algorithms defined by Ulrich Drepper.
70 See L<https://www.akkadia.org/drepper/SHA-crypt.txt>.
72 =item B<-salt> I<string>
74 Use the specified salt.
75 When reading a password from the terminal, this implies B<-noverify>.
79 Read passwords from I<file>.
83 Read passwords from B<stdin>.
87 Don't verify when reading a password from the terminal.
91 Don't output warnings when passwords given at the command line are truncated.
95 In the output list, prepend the cleartext password and a TAB character
96 to each password hash.
100 When the B<-table> option is used, reverse the order of cleartext and hash.
