=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.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print out a usage message.
|
|
|
|
=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<-aixmd5>
|
|
|
|
Use the B<AIX MD5> algorithm (AIX variant of the BSD algorithm).
|
|
|
|
=item B<-5>
|
|
|
|
=item B<-6>
|
|
|
|
Use the B<SHA256> / B<SHA512> based algorithms defined by Ulrich Drepper.
|
|
See L<https://www.akkadia.org/drepper/SHA-crypt.txt>.
|
|
|
|
=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.
|
|
|
|
=item B<-rand file...>
|
|
|
|
A file or files containing random data used to seed the random number
|
|
generator.
|
|
Multiple files can be specified separated by an OS-dependent character.
|
|
The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
|
|
all others.
|
|
|
|
=item [B<-writerand file>]
|
|
|
|
Writes random data to the specified I<file> upon exit.
|
|
This can be used with a subsequent B<-rand> flag.
