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. |

|
|

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>. |
