02. RSA Encryption and Decryption

RSA Encryption and Decryption

Overview

RSA is used for asymmetric encryption. Ideal for encrypting small payloads like keys or tokens.

API Reference

• CryptoKit.encryptRSA(data: String, publicKey: String): String
• CryptoKit.decryptRSA(data: String, privateKey: String): String

Example

// RSA Encryption
val publicKey = loadPublicKey() // Load your RSA public key
val privateKey = loadPrivateKey() // Load your RSA private key
val data = "Confidential Data"
val encryptedData = CryptoKit.encryptRSA(data, publicKey)
println("Encrypted: $encryptedData")

// RSA Decryption
val decryptedData = CryptoKit.decryptRSA(encryptedData, privateKey)
println("Decrypted: $decryptedData")

Notes

• Public and private keys must be PEM-encoded.
• Suitable for encrypting small data only.
