我试图将用C#编写的代码转换为目标c,我试过但无法得到相同的结果.任何帮助都会很明显.
internal static class Common {
static string encryptionKey = "0C61L2FSL2F3E7X8E9T1L2F3E4O5";
static byte[] salt = new byte[] {0x49,0x76,0x61,0x6e,0x20,0x4d,0x65,0x64,0x76};
internal static string Encrypt(string clearText)
{
byte[] clearBytes = Encoding.Unicode.GetBytes(clearText);
using (Aes encryptor = Aes.Create())
{
Rfc2898DeriveBytes pdb = new Rfc2898DeriveBytes(encryptionKey,salt);
encryptor.Key = pdb.GetBytes(32);
encryptor.IV = pdb.GetBytes(16);
using (MemoryStream ms = new MemoryStream())
{
using (CryptoStream cs = new CryptoStream(ms,encryptor.CreateEncryptor(),CryptoStreamMode.Write))
{
cs.Write(clearBytes,clearBytes.Length);
cs.Close();
}
clearText = Convert.ToBase64String(ms.ToArray());
}
}
return clearText;
}
}
以上代码用于加密.我试图获得RFC2898derivebytes的等效函数.
我试过的客观代码：
-(void)doEncryption {
NSString *url = @"www.google.com";
const char salt[] = {0x49,0x76};
NSData *saltData =[NSData dataWithBytes:salt length:13];
NSData* myPassData = [EncryptionKey dataUsingEncoding:NSUTF8StringEncoding];
unsigned char key[32];
CCKeyDerivationPBKDF(kCCPBKDF2,myPassData.bytes,myPassData.length,saltData.bytes,saltData.length,kCCPRFHmacAlgSHA1,1000,key,32);
unsigned char InitialVector[16];
CCKeyDerivationPBKDF(kCCPBKDF2,InitialVector,16);
NSString *Aeskey = [[NSString alloc] initWithBytes:key length:sizeof(key) encoding:NSUnicodeStringEncoding];
NSLog(@"Key AES : %@",Aeskey);
NSString *AesIV = [[NSString alloc] initWithBytes:InitialVector length:sizeof(key) encoding:NSASCIIStringEncoding];
NSString *encryptedString = [AESCrypt encrypt:url password:Aeskey andIV:AesIV];
[self doDecryption:encryptedString withKey:nil];
}
