01 AES Encryption and Decryption

ES Encryption and Decryption

Overview

AES (Advanced Encryption Standard) is used for symmetric encryption. CryptoKit uses the AES-GCM mode for secure encryption.

API Reference

• CryptoKit.encryptAES(data: String, key: String): String
• CryptoKit.decryptAES(data: String, key: String): String

Example

// Encryption
val key = "my_secure_key_123" // Ensure it's 128/192/256 bits
val data = "Sensitive Information"
val encryptedData = CryptoKit.encryptAES(data, key)
println("Encrypted: $encryptedData")

// Decryption
val decryptedData = CryptoKit.decryptAES(encryptedData, key)
println("Decrypted: $decryptedData")

Notes

• Ensure the key length matches the AES-GCM requirements.
• Encrypted data is returned as Base64-encoded.
