README

some useful cmds.

Example:

append to your root cmd.

import (
	gcmd "github.com/Laisky/go-utils/v4/cmd"
)

func init() {
	rootCmd.AddCommand(gcmd.EncryptCMD)
}

EncryptAESCMD encrypt files by aes

`go run cmd/main/main.go encrypt aes -i cmd/root.go -s 123`

var EncryptCMD = &cobra.Command{
	Use:   "encrypt",
	Short: "encrypt file or directory",
	Long: gutils.Dedent(`
		encrypt file or directory by aes

		Usage

			import (
				gcmd "github.com/Laisky/go-utils/v4/cmd"
			)

			func init() {
				rootCMD.AddCommand(gcmd.EncryptCMD)
			}

		Run

			go run -race main.go encrypt aes -i <file_path> -s <password>
	`),
	Args: NoExtraArgs,

EncryptCMD encrypt files

var RSA = &cobra.Command{
	Use:   "rsa",

RSA some rsa command tools

var RSASign = &cobra.Command{

RSASign sign file by rsa

var RSAVerify = &cobra.Command{
	Use:   "verify",
	Short: "verify by RSA & SHA256",
	Args:  NoExtraArgs,
	Run: func(cmd *cobra.Command, args []string) {

RSAVerify verify file by rsa

Functions

func Execute

func Execute()

Execute adds all child commands to the root command and sets flags appropriately. This is called by main.main(). It only needs to happen once to the rootCmd.

func NoExtraArgs

func NoExtraArgs(_ *cobra.Command, args []string) error

NoExtraArgs make sure every args has been processed

do not allow any unprocessed args

Example

use with cobra.Command:

cmd = &cobra.Command{
    Args: NoExtraArgs,
}

func SignFileByRSA

func SignFileByRSA(prikeyPath, filePath string) error

SignFileByRSA sign file by rsa

func VerifyFileByRSA

func VerifyFileByRSA(pubkeyPath, filePath string) error

VerifyFileByRSA verify file by rsa
