🗂 SKSecurity

SKSecurity는 고급 암호화 표준 (Advanced Encryption Standard, AES)를 기반으로 입력받은 데이터를 AES-128, AES-192, AES-256들의 대칭키 (Symmetric) 크기를 바탕으로 암호화 또는 복호화 작업을 수행할 수 있습니다. 또한, CBC (Cipher Block Chaining mode) 기반으로 동작하기에 초기화 백터 값이 필요합니다.

• AES (Advanced Encryption Standard) 암호화 기법에 대한 자세한 설명은 Advanced Encryption Standard 확인 부탁드립니다.

고급 암호화 표준 (Advanced Encryption Standard, AES) 키의 크기 제약 조건은 아래를 반드시 지켜야 합니다.

• An AES 128-bit key can be expressed as a hexadecimal string with 32 characters. It will require 24 characters in base64.

• An AES 192-bit key can be expressed as a hexadecimal string with 48 characters. It will require 32 characters in base64.

• An AES 256-bit key can be expressed as a hexadecimal string with 64 characters. It will require 44 characters in base64.

SKSecurity 예제 소스코드는 아래와 같습니다.

// AES 암호화를 수행하기 위한 IV를 생성합니다.
let iv = SKSecurity.shared().createInitializationVector()
print(iv)

let key = "a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2"

// AES 암호화를 수행하기 위한 평문을 생성합니다.
if let rawData = "PASSWORD".data(using: .utf8) {

    // AES 암호화를 수행합니다.
    let encrypted = SKSecurity.shared().encrypt(key, .AES256, iv, rawData)

    // AES 복호화를 수행합니다.   
    let decrypted = SKSecurity.shared().decrypt(key, .AES256, iv, encrypted)
    print(String(data: decrypted, encoding: .utf8))
}
