Struct schnorrkel::vrf::Malleable

source · 
pub struct Malleable<T: SigningTranscript>(pub T);
Expand description

VRF SigningTranscript for malleable VRF outputs.

Warning We caution that malleable VRF outputs are insecure when used in conjunction with HDKD, as provided in dervie.rs. Attackers could translate malleable VRF outputs from one soft subkey to another soft subkey, gaining early knowledge of the VRF output. We think most VRF applications for which HDKH sounds suitable benefit from using implicit certificates instead of HDKD anyways, which should also be secure in combination with HDKD. We always use non-malleable VRF inputs in our convenience methods.
