5 passwd - compute password hashes
24 The B<passwd> command computes the hash of a password typed at
25 run-time or the hash of each password in a list. The password list is
26 taken from the named file for option B<-in file>, from stdin for
27 option B<-stdin>, or from the command line, or from the terminal otherwise.
28 The Unix standard algorithm B<crypt> and the MD5-based BSD password
29 algorithm B<1> and its Apache variant B<apr1> are available.
37 Print out a usage message.
41 Use the B<crypt> algorithm (default).
45 Use the MD5 based BSD password algorithm B<1>.
49 Use the B<apr1> algorithm (Apache variant of the BSD algorithm).
51 =item B<-salt> I<string>
53 Use the specified salt.
54 When reading a password from the terminal, this implies B<-noverify>.
58 Read passwords from I<file>.
62 Read passwords from B<stdin>.
66 Don't verify when reading a password from the terminal.
70 Don't output warnings when passwords given at the command line are truncated.
74 In the output list, prepend the cleartext password and a TAB character
75 to each password hash.
81 B<openssl passwd -crypt -salt xx password> prints B<xxj31ZMTZzkVA>.
83 B<openssl passwd -1 -salt xxxxxxxx password> prints B<$1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a.>.
85 B<openssl passwd -apr1 -salt xxxxxxxx password> prints B<$apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0>.
