The password list is 32taken from the named file for option B<-in>, from stdin for 33option B<-stdin>, or from the command line, or from the terminal otherwise. 34 35=head1 OPTIONS 36 37=over 4 38 39=item B<-help> 40 41Print out a usage message. 42 43=item B<-1> 44 45Use the MD5 based BSD password algorithm B<1> (default). 46 47=item B<-apr1> 48 49Use the B<apr1> algorithm (Apache variant of the BSD algorithm). 50 51=item B<-aixmd5> 52 53Use the B<AIX MD5> algorithm (AIX variant of the BSD algorithm). 54 55=item B<-5> 56 57=item B<-6> 58 59Use the B<SHA256> / B<SHA512> based algorithms defined by Ulrich Drepper. 60See L<https://www.akkadia.org/drepper/SHA-crypt.txt>. 61 62=item B<-salt> I<string> 63 64Use the specified salt. 65When reading a password from the terminal, this implies B<-noverify>. 66 67=item B<-in> I<file> 68 69Read passwords from I<file>. 70 71=item B<-stdin> 72 73Read passwords from B<stdin>. 74 75=item B<-noverify> 76 77Don't verify when reading a password from the terminal. 78 79=item B<-quiet> 80 81Don't output warnings when passwords given at the command line are truncated. 82 83=item B<-table> 84 85In the output list, prepend the cleartext password and a TAB character 86to each password hash. 87 88=item B<-reverse> 89 90When the B<-table> option is used, reverse the order of cleartext and hash. 91 92{- $OpenSSL::safe::opt_r_item -} 93 94{- $OpenSSL::safe::opt_provider_item -} 95 96=back 97 98=head1 EXAMPLES 99 100 % openssl passwd -1 -salt xxxxxxxx password 101 $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a. 102 103 % openssl passwd -apr1 -salt xxxxxxxx password 104 $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0 105 106 % openssl passwd -aixmd5 -salt xxxxxxxx password 107 xxxxxxxx$8Oaipk/GPKhC64w/YVeFD/ 108 109=head1 HISTORY 110 111The B<-crypt> option was removed in OpenSSL 3.0. 112 113=head1 COPYRIGHT 114 115Copyright 2000-2021 The OpenSSL Project Authors.
