Golang and Vault: Building a reliable authorization system
Golang and Vault: Building a reliable authorization system
Introduction:
In today's Internet era, the authorization system is a very important component. It is widely used in various fields, such as user authentication, API access control, etc. In order to build a reliable authorization system, we need to use modern technology and tools. In this article, we will introduce how to use Golang and Vault to build a reliable authorization system, and provide corresponding code examples.
1. What is Golang?
Golang is an open source programming language developed and launched by Google. It is designed as a language for building efficient, reliable and concise software. Golang has many advantages, such as static typing, garbage collection, efficient concurrency model, etc., making it a very suitable choice for building authorization systems.
2. What is Vault?
Vault is an open source tool for managing, protecting, and distributing keys, passwords, and credentials for accessing private information. It provides a unified interface and API for securely storing and accessing sensitive data. Vault supports many authentication methods, such as username/password, TLS certificate, LDAP, etc., and provides fine-grained access control.
3. Use Golang and Vault to build an authorization system
The following is a sample code for using Golang and Vault to build an authorization system:
package main
import (
"github.com/hashicorp/vault/api"
)
func main() {
// Create a Vault client
client, err := api.NewClient(&api. Config{
Address: "http://localhost:8200", // Vault server的地址
})
if err != nil {
panic(err)
}
// Set Vault’s Token
client.SetToken("token" )
// Get the access control list from Vault
secret, err := client.Logical().Read("secret/myapp/acl")
if err != nil {
panic(err)
}
// Check whether the user has permission to access
if secret == nil || secret.Data["acl"].(string) != "allow" {
panic("Access denied")
}
// Authorization passed, perform corresponding operations
// TODO: Execute your code logic
}
The above example code uses Vault Golang client library, first create a Vault client and set the access address. Then, authenticate the Vault by setting the Vault's Token. Next, read the access control list from Vault and determine whether to allow access based on permissions. Finally, if the authorization is passed, the corresponding operation is performed.
4. Summary
In this article, we introduced how to use Golang and Vault to build a reliable authorization system. By using the advantages of Golang and the security features of Vault, we can easily build an efficient, reliable and secure authorization system. I hope this article has provided you with some help building an authorization system and encourages you to continue exploring and learning these tools and techniques.

The reason for using interfaces for simulation and testing is that the interface allows the definition of contracts without specifying implementations, making the tests more isolated and easy to maintain. 1) Implicit implementation of the interface makes it simple to create mock objects, which can replace real implementations in testing. 2) Using interfaces can easily replace the real implementation of the service in unit tests, reducing test complexity and time. 3) The flexibility provided by the interface allows for changes in simulated behavior for different test cases. 4) Interfaces help design testable code from the beginning, improving the modularity and maintainability of the code.

In Go, the init function is used for package initialization. 1) The init function is automatically called when package initialization, and is suitable for initializing global variables, setting connections and loading configuration files. 2) There can be multiple init functions that can be executed in file order. 3) When using it, the execution order, test difficulty and performance impact should be considered. 4) It is recommended to reduce side effects, use dependency injection and delay initialization to optimize the use of init functions.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
