Discription

it is a BLS signature lib for golang

How to install the lib

First :install the GMP

This package must be compiled using cgo. It also requires the installation of GMP and PBC. During the build process, this package will attempt to include <gmp.h> and <pbc/pbc.h>, and then dynamically link to GMP and PBC.

Most systems include a package for GMP. To install GMP in Debian / Ubuntu:

sudo apt-get install libgmp-dev

For an RPM installation with YUM:

sudo yum install gmp-devel

For installation with Fink (http://www.finkproject.org/) on Mac OS X:

sudo fink install gmp gmp-shlibs

For more information or to compile from source, visit https://gmplib.org/

Second:install the PBC

To install the PBC library, download the appropriate files for your system from https://crypto.stanford.edu/pbc/download.html. PBC has three dependencies: the gcc compiler, flex (http://flex.sourceforge.net/), and bison (https://www.gnu.org/software/bison/). See the respective sites for installation instructions. Most distributions include packages for these libraries. For example, in Debian / Ubuntu:

sudo apt-get install build-essential flex bison

The PBC source can be compiled and installed using the usual GNU Build System:

./configure
make
sudo make install

After installing, you may need to rebuild the search path for libraries:

sudo ldconfig

It is possible to install the package on Windows through the use of MinGW and MSYS. MSYS is required for installing PBC, while GMP can be installed through a package. Based on your MinGW installation, you may need to add "-I/usr/local/include" to CPPFLAGS and "-L/usr/local/lib" to LDFLAGS when building PBC. Likewise, you may need to add these options toCGO_CPPFLAGSand CGO_LDFLAGS when installing this package.

and then install the golang pbc lib

go get github.com/Nik-U/pbc

Third: install the BLS signature golang lib

download the bls signature lib

go get go get github.com/yunfeiyangbuaa/bls_golang_lib/BLS

and imprt in your code

import " github.com/yunfeiyangbuaa/bls_golang_lib/BLS"

How to use

Exmple

func main() {
   	BLS.BLS_start() 
   	privKey,pubKey:=BLS.Generate_bls_keypair()    
   	signature :=BLS.Bls_signature([]byte("hello") ,privKey)      
   	sibyte:=BLS.SetSIGIntoByte(signature)     
   	sign:=BLS.SetPubKeyFromByte(sibyte)     
   	BLS.Bls_verify([]byte("hello") ,pubKey,sign)      
   }

Function

    Generate_bls_keypair()(*pbc.Element,*pbc.Element)　　　　
    Bls_signature(message  []byte,privkey *pbc.Element) *pbc.Element　　
    Bls_verify(message  []byte,pubkey  *pbc.Element,signature  *pbc.Element)bool　　
    func SetPriKeyIntoByte(privkey  *pbc.Element)[]byte    
    func SetPriKeyFromByte(privkey  []byte)*pbc.Element
    func SetPubKeyIntoByte(pubkey  *pbc.Element)[]byte
    func SetPubKeyFromByte(pubkey  []byte)*pbc.Element
    func SetSIGIntoByte(sig  *pbc.Element)[]byte
