Is there any library/tool available which can allow me to search over encrypted data? I would like to encrypt data on client side, send it to cloud and perform search in cloud.
I've been reading about homomorphic encryption and though there is CryptDb available which makes it possible to run encrypted DB in cloud, but my use case is slightly different- in my case I want to let users send me encrypted data and I want to be able to do a keyword search (as opposed to user performing search).
