BBS curves and BBS+ keypairs

This trait exposes signature and keytype primitives based on BBS+ cryptography.

Structs

• BlsKeyPair
  A BLS keypair where the public key can be in either G1 or G2
• BlsPublicKey
  A BLS public key where the public key can be either in G1 or G2
• BlsSecretKey
  A Bls and BBS+ secret key

Enums

• BlsGenerateKeyPairError
  Error resulting from attempting to generate a BLS Keypair
• BlsToBbsPublicKeyError
  Error resulting from attempting to convert a BlsPublicKey or BlsSecretKey to a BBS+ Public Key

Constants

• BLINDING_G1
  This shows how the generators are created with nothing up my sleeve values
• BLINDING_G2

Functions

• bls_generate_blinded_g1_key
  Generate a blinded BLS key pair where secret key x and blinding factor r in Fr and public key W = G1 * x * Blinding_G1 * r
• bls_generate_blinded_g2_key
  Generate a blinded BLS key pair where secret key x and blinding factor r in Fr and public key W = G2 * x * Blinding_G2 * r
• bls_generate_g1_key
  Generate a BLS key pair where secret key x in Fr and public key W = G1 * x
• bls_generate_g2_key
  Generate a BLS key pair where secret key x in Fr and public key W = G1 * x
