Sypher Example

This application madly prints credentials to console 😳🤓

How did I create this project?

Created project directory:

$ mkdir sypher-example && cd sypher-example

Initialized new module:

$ go mod init github.com/sertangulveren/sypher-example

Created main.go:

$ touch main.go

Edited main.go as follows:

package main

import "fmt"

func main() {
	fmt.Println("Hello Sypher")
}

Ran app and confirmed: It works fantastically:

$ go run main.go 
Hello Sypher

Installed sypher package:

$ go get -u github.com/sertangulveren/sypher

Installed sypher cli:

$ go install github.com/sertangulveren/sypher/sypher@latest

Generated a credential file named myconfig via sypher to store API keys to use in my project:

$ sypher gen myconfig
Created: myconfig
Done!

Checked the project directory:

Files generated for myconfig in sypher folder.

• myconfig.enc encrypted file.
• myconfig.key key file.
• sypher.go to register encrypted file as embedded.

$ tree

├── README.md
├── go.mod
├── main.go
└── sypher
    ├── myconfig.enc
    ├── myconfig.key
    └── sypher.go

1 directory, 6 files

Ignored key files:

It just creates or modifies .gitignore file to ignore key files. You can add manually sypher/*.key to your .gitignore file instead of use the command.

$ sypher gitignore

Updated the credentials: It opens vim editor by default.

$ sypher edit myconfig

To use another editor like nano, code etc. set EDITOR variable. Example:

$ EDITOR=code sypher edit myconfig

Changed and saved the content as below and closed the editor:

AWS_ACCESS_KEY=niceaccesskey
AWS_ACCESS_SECRET_KEY=hereisthesecretk3y
HOLY_API_KEY=123

Edited the main.go file again:

package main

import (
	"fmt"
	"github.com/sertangulveren/sypher"
	_ "github.com/sertangulveren/sypher-example/sypher"
)

func main() {
	sypher.Load(sypher.Config{
		Name: "myconfig",
	})

	awsKey := sypher.Get("AWS_ACCESS_KEY")
	awsSecret := sypher.Get("AWS_ACCESS_SECRET_KEY")
	holyKey := sypher.Get("HOLY_API_KEY")

	// print my environment variables
	fmt.Println(awsKey)
	fmt.Println(awsSecret)
	fmt.Println(holyKey)
}

Ran app and confirmed again: It works!:

$ go run main.go 
niceaccesskey
hereisthesecretk3y
123

Built the application:

go build -o sypher-example main.go

Ran it in another instance/server:

./sypher-example

Before running, I assigned the key value in the myconfig.key file to the SYPHER_MASTER_KEY variable. If you want to do this manually with the command:

SYPHER_MASTER_KEY=mykeycontent ./sypher-example

you can clone this project:

With SSH:

git clone git@github.com:sertangulveren/sypher-example.git

OR HTTPS:

git clone https://github.com/sertangulveren/sypher-example.git

You can create sypher/myconfig.key file with content:

RFbD67TI3smTyVsGd6Xav1yu00ZAMPTA

Run: go run main.go

---

Instead of creating key file, you can also run it by assigning the SYPHER_MASTER_KEY variable.
