Part of the reason I’ve been able to raise money and spend several years of my life trying to build and evangelize this new/better way of protecting passwords is because the USPTO has granted us the exclusive right to license it in the US through ~2033.
- deckar01 9y agoThat is a much better patent. Sorry for the confusion. The "index into a random data block" is already a primitive cryptographic operation in key expansion and hashing algorithms, but the block is deterministically generated pseudo randomly from a seed. It would be interesting to replace the seeding operation with an offset into a large static pool generated from a source of true randomness.
