Module dock_runtime::offchain_signatures

Module to store offchain signature keys and parameters for different signature schemes. Currently, can be either BBS, BBS+, Pointcheval-Sanders or BBDT16. For BBS, BBS+ and Pointcheval-Sanders, the public key is in group G2 but for BBDT16, it’s in group G1 and used to verify the proof of validity of MAC (and related proofs) but not the MAC itself.
