Secure password hashing in Go is a crucial aspect of maintaining the security and integrity of user credentials. In this article, we'll explore various hashing algorithms and their implementation in Go, focusing on Argon2id, scrypt, bcrypt, and PBKDF2. We'll discuss best practices for password hashing, including salting, iteration count, and handling hash collisions. By following these guidelines and using secure hashing algorithms, you can protect user passwords from unauthorized access and ensure the overall security of your application.
