sudo cryptsetup isLuks /dev/sdb1
and/or
sudo cryptsetup luksDump /dev/sdb1

//from the manpage http://linux.die.net/man/8/cryptsetup

isLuks <device>

returns true, if <device> is a LUKS partition. Otherwise, false. No
options.

luksDump <device>

dumps the header information of a LUKS partition. No options.
//manpage end
