RSS3 Go Lib

A go lib for RSS3

Usage

Types

This package includes main types of RSS3, including:

• RSS3Base
• RSS3
• RSS3List
• RSS3Item

Also, with useful methods like *.SetSign, and *.CheckSign.

Using like this can create signature for your RSS3 Persona demo.

var key *ecdsa.PrivateKey

...

var demo types.RSS3

demo.SetSign(key)

And this can check if the signer and embedded signature matches.

demo.CheckSign()

For other demos, you can check those *_test.go files for more help.

Utils

Contains some useful tools:

• FixSign
• SignMsg

FixSign

This function can delete the starting "0x" of signature (if it has), and fix the ending (eth-crypto library would somewhat add 0x1b to the last byte, causing it change from 00/01 to 1b/1c, which will crash the requested functions)

utils.FixSign(signatureReceived)

SignMsg

This function can be used to create signatures for []byte . Here's a demo with a string.

var key *ecdsa.PrivateKey

...

msgBytes := []byte("DemoMsg")

sign := utils.SignMsg(key, msgBytes)

signHex := hex.EncodeToString(sign)

Inner Types

(Recommend not to use outside this package)

• types/for_sign.go: types derived of useless fields for creating signature.

  Those types often ends with 4S which means "For(4) Sign"

• types/for_file.go: full types with all fields (as described in definition) for storage use.

  Those types often ends with 4F which means "For(4) File"
