问题 Im using the following code to encrypt and decrypt a string using AES Encryption.I'm using common crypto by adding a Bridging Header. extension String { func aesEncrypt(key:String, iv:String, options:Int = kCCOptionPKCS7Padding) -> String? { if let keyData = key.data(using: String.Encoding.utf8), let data = self.data(using: String.Encoding.utf8), let cryptData = NSMutableData(length: Int((data.count)) + kCCBlockSizeAES128) { let keyLength = size_t(kCCKeySizeAES128) let operation: CCOperation

问题 I really need some help to convert the objective-c code to swift using CryptoSwift . I'm not sure how to use functions like: bzero , getCString , malloc in Swift. +(NSData*)encryptData:(NSData*)data { static NSString *key = @"BitCave012345678"; char keyPtr[kCCKeySizeAES128+1]; bzero(keyPtr, sizeof(keyPtr)); [key getCString:keyPtr maxLength:sizeof(keyPtr) encoding:NSUTF8StringEncoding]; NSUInteger dataLength = [data length]; size_t bufferSize = dataLength + kCCBlockSizeAES128; void *buffer =

How to convert bytes to NSString after AES CryptoSwift cipher

由 左心房为你撑大大i 提交于 2020-01-02 07:03:48
问题 I am using CryptoSwift to encrypt data I will be passing in a URL. To do this, I need the datatype of the piece of data to be a String to concatenate into the NSURL request. After encrypting the data it is output in bytes. How can I cast the bytes to a nonsense string to pass in the URL that a PHP script can decrypt? I am able to encrypt into UInt8, however I do not think it is possible to pass it over a URL to PHP script so I need to make it a string. The code: let string = "hello" let input

HMAC SHA256 in Swift 4

由 别等时光非礼了梦想. 提交于 2019-12-24 00:48:36
问题 I have a string and a key, which i want to generate an HMAC SHA256 from it. Although i'm using 2 libs IDZSwiftCommonCrypto and CryptoSwift and this answer Nothing really worked for me. My source of truth are those 2 websites https://myeasywww.appspot.com/utility/free/online/Crypt_Decrypt-MD5-AES-HMAC-SHA-DES-RABBIT/en?command=UTILITY&ID=2 and https://www.freeformatter.com/hmac-generator.html#ad-output Which they always generate the correct hash key for my case. Any idea in what can work here?

问题 I am building a social media application and I would like some help encoding a password string to SHA512 in Swift. I found the CryptoSwift library on GitHub but I am having a hard time loading it into my Swift project and linking it to my project files. Does anyone know how to accomplish this relatively easily? Thanks in advance, Kyle 回答1: Solution for Swift 3 : extension String { func sha512() -> String { let data = self.data(using: .utf8)! var digest = [UInt8](repeating: 0, count: Int(CC

I write an application by swift, i need AES Encrypt and Decrypt functionality, i received encrypted data from another .Net solution, but i can't find something to do it. This is my .net Encryption: public static byte[] AES_Encrypt(byte[] bytesToBeEncrypted, byte[] passwordBytes) { byte[] encryptedBytes = null; byte[] saltBytes = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8 }; using (MemoryStream ms = new MemoryStream()) { using (RijndaelManaged AES = new RijndaelManaged()) { AES.KeySize = 256; AES.BlockSize = 128; var key = new Rfc2898DeriveBytes(passwordBytes, saltBytes, 1000); AES.Key = key.GetBytes
