ios swift5 AES加密，解密

用第三框架CryptoSwift

CryptoSwift - github

• 下面的代码本人亲测有效

do {
    
    
    let aes = try AES(key: "keykeykeykeykeyk", iv: "drowssapdrowssap") // aes128
    let ciphertext = try aes.encrypt(Array("Nullam quis risus eget urna mollis ornare vel eu leo.".utf8))
} catch {
    
     }

• 不能加密大文件，本人试图加密200M的大文件，结果直接卡死，cpu跑到100%
