How can I generate a SHA512-hashed password? openssl seems not to be able to do that.
Code:
$ uname -a
FreeBSD kraken 9.2-RC3 FreeBSD 9.2-RC3 #0 r254795: Sat Aug 24 20:25:04 UTC 2013 root@bake.isc.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64
$ openssl passwd -help
Usage: passwd [options] [passwords]
where options are
-crypt standard Unix password algorithm (default)
-1 MD5-based password algorithm
-apr1 MD5-based password algorithm, Apache variant
-salt string use provided salt
-in file read passwords from file
-stdin read passwords from stdin
-noverify never verify when reading password from terminal
-quiet no warnings
-table format output as table
