DESCRIPTION

The 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 −in file, from stdin for option −stdin, and from the command line otherwise. The Unix standard algorithm crypt and the MD5-based apr1 algorithm are available.

OPTIONS

−crypt

Use the crypt algorithm (default).

−apr1

Use the apr1 algorithm.

−salt string

Use the specified salt.

−in file

Read passwords from file.

−stdin

−quiet

Don’t output warnings when passwords given at the command line are truncated.

−table

In the output list, prepend the cleartext password and a TAB character to each password hash.

EXAMPLES

openssl passwd −crypt −salt xx password prints xxj31ZMTZzkVA.

openssl passwd −apr1 −salt xxxxxxxx password prints $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0.
