🔐 Crypto is My guy (for Keeping Secrets)

Cryptography is the art of secret messaging, turning messages into unreadable gibberish until decrypted with the right key.
There are two main types of cryptography: Symmetric (using a shared key) and Asymmetric (using public and private keys).
Cryptography is used in everyday applications like secure websites, messaging apps, online payments, and banking to ensure data security.
Modern algorithms like AES, RSA, ECC, and SHA-256 are utilized for encryption, hashing, and securing various digital transactions.

Go Struct: What Happens When You Add a '_' Field?

The Go programming language often uses the underscore (_) as a placeholder for various purposes, but using it as a field within a struct is less common.
Adding an underscore (_) field in a struct enforces named field initialization, preventing the use of positional initialization.
Positional initialization with an underscore (_) field will result in compilation errors due to too few values or implicit assignment to an unexported field.
By using named field initialization, code readability improves, error prevention increases, and struct initialization becomes more explicit in Go programming.
