README

GoRSA Encryption library

based on https://github.com/farmerx/gorsa Optimized the following points for packaging:

  • Optimization of public and private keys requires registration and initialization in advance.
  • The encryption machine does not perform base64 processing, and avoids secondary encapsulation of base64 during cross-program transfer or storage
  • The incoming return uses the string type uniformly to avoid conversion trouble
  • Supports RSAWithSHA1 and RSAWithSHA256 signature verification algorithms

Get expansion pack:

go get github.com/wenzhenxi/gorsa

Specific use:

package main

import (
	"log"
	"errors"
	"github.com/wenzhenxi/gorsa"
)
