Author: pjd

New Revision: 213172
URL: http://svn.freebsd.org/changeset/base/213172
Log:
- Add support for loading passphrase from a file (-J and -j options).
This is especially useful for things like installers, where regular
geli prompt can't be used.
- Add support for specifing multiple -K or -k options, so there is no
need to cat all keyfiles and read them from standard input.
