| |
| passwd - compute password hashes |
| |
| =head1 SYNOPSIS |
| |
| B<openssl passwd> |
| [B<-crypt>] |
| [B<-1>] |
| [B<-apr1>] |
| [B<-salt> I<string>] |
| [B<-in> I<file>] |
| [B<-stdin>] |
| [B<-noverify>] |
| [B<-quiet>] |
| [B<-table>] |
| {I<password>} |
| |
| =head1 DESCRIPTION |
| |
| The B<passwd> command computes the hash of a password typed at |
| run-time or the hash of each password in a list. The password list is |
| taken from the named file for option B<-in file>, from stdin for |
| option B<-stdin>, or from the command line, or from the terminal otherwise. |
| The Unix standard algorithm B<crypt> and the MD5-based BSD password |
| algorithm B<1> and its Apache variant B<apr1> are available. |
| |
| =head1 OPTIONS |
| |
| =over 4 |
| |
| =item B<-crypt> |
| |
| Use the B<crypt> algorithm (default). |
| |
| =item B<-1> |
| |
| Use the MD5 based BSD password algorithm B<1>. |
| |
| =item B<-apr1> |
| |
| Use the B<apr1> algorithm (Apache variant of the BSD algorithm). |
| |
| =item B<-salt> I<string> |
| |
| Use the specified salt. |
| When reading a password from the terminal, this implies B<-noverify>. |
| |
| =item B<-in> I<file> |
| |
| Read passwords from I<file>. |
| |
| =item B<-stdin> |
| |
| Read passwords from B<stdin>. |
| |
| =item B<-noverify> |
| |
| Don't verify when reading a password from the terminal. |
| |
| =item B<-quiet> |
| |
| Don't output warnings when passwords given at the command line are truncated. |
| |
| =item B<-table> |
| |
| In the output list, prepend the cleartext password and a TAB character |
| to each password hash. |

| =head1 EXAMPLES |
| |
| B<openssl passwd -crypt -salt xx password> prints B<xxj31ZMTZzkVA>. |
| |
| B<openssl passwd -1 -salt xxxxxxxx password> prints B<$1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a.>. |
| |
| B<openssl passwd -apr1 -salt xxxxxxxx password> prints B<$apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0>. |
