Struct signature_bbs_plus::Issuer
source · [−]pub struct Issuer;
Expand description
This struct represents an Issuer of signatures or Signer. Provided are methods for signing regularly where all messages are known and 2PC where some are only known to the holder and a blind signature is created.
The issuer generates keys and uses those to sign credentials.
