  29 =head1 DESCRIPTION
  30
  31 This command computes the hash of a password typed at
  32 run-time or the hash of each password in a list.  The password list is
  33 taken from the named file for option B<-in>, from stdin for
  34 option B<-stdin>, or from the command line, or from the terminal otherwise.
  35 The Unix standard algorithm B<-crypt> and the MD5-based BSD password
  36 algorithm B<-1>, its Apache variant B<-apr1>, and its AIX variant are
  37 available.

  40
  41 =over 4
  42
  43 =item B<-help>
  44
  45 Print out a usage message.
  46
  47 =item B<-crypt>
  48
  49 Use the B<crypt> algorithm (default).
  50
  51 =item B<-1>
  52
  53 Use the MD5 based BSD password algorithm B<1>.
  54
  55 =item B<-apr1>
  56
  57 Use the B<apr1> algorithm (Apache variant of the BSD algorithm).
  58
  59 =item B<-aixmd5>
  60
  61 Use the B<AIX MD5> algorithm (AIX variant of the BSD algorithm).
  62
  63 =item B<-5>
  64
  65 =item B<-6>
  66
  67 Use the B<SHA256> / B<SHA512> based algorithms defined by Ulrich Drepper.
  68 See L<https://www.akkadia.org/drepper/SHA-crypt.txt>.
  69
  70 =item B<-salt> I<string>
  71
  72 Use the specified salt.
  73 When reading a password from the terminal, this implies B<-noverify>.
  74
  75 =item B<-in> I<file>
  76
  77 Read passwords from I<file>.
  78
  79 =item B<-stdin>
  80
  81 Read passwords from B<stdin>.
  82
  83 =item B<-noverify>
  84
  85 Don't verify when reading a password from the terminal.
  86
  87 =item B<-quiet>
  88
  89 Don't output warnings when passwords given at the command line are truncated.
  90
  91 =item B<-table>
  92
  93 In the output list, prepend the cleartext password and a TAB character
  94 to each password hash.
