What kind of Bracha does a father give to his daughter-in-law by Badekin?

The written custom [Kitzur Shulchan Aruch 147 3-4] is that the Kallah is blessed [and not only by her father] with the words Rivkah was blessed before her marriage: "Our sister - may you become to be thousands of myriads and your offspring will inherit its enemies". [Bereshit 24:60]
