事实证明，我完全把这个复杂化了。
我不需要导入任何外部库或SDK，我只需要一个桥接头文件即可 #import <CommonCrypto/CommonCrypto.h>
override func viewDidLoad() {
super.viewDidLoad()
myEncrypt("my string to encrypt")
}
func myEncrypt(encryptData:String) -> NSData?{
var myKeyData : NSData = ("myEncryptionKey" as NSString).dataUsingEncoding(NSUTF8StringEncoding)!
var myRawData : NSData = encryptData.dataUsingEncoding(NSUTF8StringEncoding)!
var iv : [UInt8] = [56, 101, 63, 23, 96, 182, 209, 205] // I didn't use
var buffer_size : size_t = myRawData.length + kCCBlockSize3DES
var buffer = UnsafeMutablePointer<NSData>.alloc(buffer_size)
var num_bytes_encrypted : size_t = 0
let operation: CCOperation = UInt32(kCCEncrypt)
let algoritm: CCAlgorithm = UInt32(kCCAlgorithm3DES)
let options: CCOptions = UInt32(kCCOptionECBMode + kCCOptionPKCS7Padding)
let keyLength = size_t(kCCKeySize3DES)
var Crypto_status: CCCryptorStatus = CCCrypt(operation, algoritm, options, myKeyData.bytes, keyLength, nil, myRawData.bytes, myRawData.length, buffer, buffer_size, &num_bytes_encrypted)
if UInt32(Crypto_status) == UInt32(kCCSuccess){
var myResult: NSData = NSData(bytes: buffer, length: num_bytes_encrypted)
free(buffer)
println("my result \(myResult)") //This just prints the data
let keyData: NSData = myResult
let hexString = keyData.toHexString()
println("hex result \(hexString)") // I needed a hex string output
myDecrypt(myResult) // sent straight to the decryption function to test the data output is the same
return myResult
}else{
free(buffer)
return nil
}
}
func myDecrypt(decryptData : NSData) -> NSData?{
var mydata_len : Int = decryptData.length
var keyData : NSData = ("myEncryptionKey" as NSString).dataUsingEncoding(NSUTF8StringEncoding)!
var buffer_size : size_t = mydata_len+kCCBlockSizeAES128
var buffer = UnsafeMutablePointer<NSData>.alloc(buffer_size)
var num_bytes_encrypted : size_t = 0
var iv : [UInt8] = [56, 101, 63, 23, 96, 182, 209, 205] // I didn't use
let operation: CCOperation = UInt32(kCCDecrypt)
let algoritm: CCAlgorithm = UInt32(kCCAlgorithm3DES)
let options: CCOptions = UInt32(kCCOptionECBMode + kCCOptionPKCS7Padding)
let keyLength = size_t(kCCKeySize3DES)
var decrypt_status : CCCryptorStatus = CCCrypt(operation, algoritm, options, keyData.bytes, keyLength, nil, decryptData.bytes, mydata_len, buffer, buffer_size, &num_bytes_encrypted)
if UInt32(decrypt_status) == UInt32(kCCSuccess){
var myResult : NSData = NSData(bytes: buffer, length: num_bytes_encrypted)
free(buffer)
println("decrypt \(myResult)")
var stringResult = NSString(data: myResult, encoding:NSUTF8StringEncoding)
println("my decrypt string \(stringResult!)")
return myResult
}else{
free(buffer)
return nil
}
}
我希望这可以帮助别人。
