signature

go-signature

Just a small library to get a signed string with a payload. It helps me to create confirmation tokens without using database.

Don't use this library to protect sensitive data!

Features

• Data Integrity: Ensures that the data remains unchanged and secure during transit.
• Simplified Token Structure: Generates tokens without the overhead of JWT headers, focusing solely on payload and signature.
• Flexibility and Ease of Use: Provides a straightforward API to work with, requiring minimal setup to sign and verify data.

Usage

Installation:

go get -u github.com/dmitrymomot/go-signature

Set up signing key

import signature "github.com/dmitrymomot/go-signature"

...
signature.SetSigningKey("secret-key")
...

Signing key will be set globally, so you don't need defining it each times

Create signed string:

import signature "github.com/dmitrymomot/go-signature"

...
signedString, _ := signature.New("some data of any type")
log.Println(signedString)
...

Output:

eyJwIjoic29tZSBkYXRhIG9mIGFueSB0eXBlIn0.MzYwMzA0ZGVhNWRmMjdjOTM0ZjY1NzU3YWUwM2I0MDZmODRiMzRiMw

Parse signed string:

data, err := signature.Parse("eyJwIjoic29tZSBkYXRhIG9mIGFueSB0eXBlIn0.MzYwMzA0ZGVhNWRmMjdjOTM0ZjY1NzU3YWUwM2I0MDZmODRiMzRiMw")
if err != nil {
    panic(err)
}
log.Println(data)

Output:

some data of any type
