Did you know? A server can help evaluate a secret-keyed function without learning the input it is evaluating. An OPRF lets the client learn the output while the server learns neither the input nor the output; a VOPRF also lets the client verify which server key was used. That makes privacy-preserving password systems possible without handing the server every value in the clear. #privacy #cryptography #cypherpunk
