rsautil

some frequenetly used rsa crypto utils, e.g.

• GenerateKey
• EncodePrivateKey
• EncodePublicKey
• Encrypt
• Decrypt
• SignWithSha256Base64
• VerySignWithSha256Base64

An example

func TestSignAndVerify(t *testing.T)  {
	sk, pk, _ := GenerateKey(1024)
	skBytes := EncodePrivateKey(sk)
	pkBytes, _ := EncodePublicKey(pk)
	fmt.Println(string(skBytes))
	fmt.Println(string(pkBytes))

	sig, err := SignWithSha256Base64("test", skBytes)
	if err != nil{
		fmt.Printf("%+v", err)
	}
	fmt.Println(sig)

	success, err := VerySignWithSha256Base64("test", sig, pkBytes)
	if success {
		fmt.Println("pass")
	} else {
		fmt.Printf("%+v", err)
	}
}
