🚀 Usage

Import Module

import CoreSecurity

---

Encrypt Data

let encrypted = try CoreSecurity.encrypt(
    data: plainTextData,
    key: secretKey
)

---

Decrypt Data

let decrypted = try CoreSecurity.decrypt(
    data: encryptedData,
    key: secretKey
)

---

Generate HMAC

let hmac = CoreSecurity.generateHMAC(
    data: payloadData,
    key: secretKey
)

---

🧩 Use Case
