Return the input that was used to create this VRF output
Return the VRF output
This is a random-looking value which was provably generated by some party with access to the VRF secret key.
Return the public key under which this VRF output was derived
Serialize a VrfOutput to a byte string
StaticdeserializeDeserialize and verify a VrfOutput
Note this verifies the VrfOutput with respect to the derived public key
and VRF input which are included in the struct. It is the responsibility
of the application to examine the return value of publicKey and input
and ensure these values make sense in the context where this VRF is being
used.
VRF (Verifiable Random Function) Output
VetKD can be used to construct a VRF, which is a public key version of a keyed hash. Like a standard keyed hash, it takes an input string and produces a output string which is indistinguishable from random. The difference between a VRF and a normal keyed hash is that a VRF can only be computed by someone with access to the VRF secret key, while the VRF output can be verified by any party with access to the public key.
For some general background on VRFs consult RFC 9381
