进出口目前写入被加密的密码(使用自定义的方法),然后编码使用To/FromBase64Transform类密码为Base64的程序。问题是,当我编码我的加密密码时,我无法将其解码回适当的加密状态。 Base64Helper类只是To/FromBase64Transform类的包装器。C#Base64编码/解码失败
我的测试代码:
static void Main(string[] args)
{
bool Worked = false;
string Password = "testing";
Console.WriteLine("Password: " + Password);
// == Encode then decode 64 test. DecPass64 should equal password == //
// Encodes to Base64 using ToBase64Transform
string EncPass64 = Base64Helper.EncodeString(Password);
// Decodes a Base64 string using FromBase64Transform
string DecPass64 = Base64Helper.DecodeString(EncPass64);
// Test if base 64 ecoding/decoding works
Worked = (Password == DecPass64);
Console.WriteLine();
Console.WriteLine("Base64 Pass Encoded: " + EncPass64);
Console.WriteLine("Base64 Pass Decoded: " + DecPass64);
Console.WriteLine("Base64 Encode to Base64 Decode Worked? : " + Worked); // True
// gspassenc uses XOR to switch passwords back and forth between encrypted and decrypted
string GsEncodedPass = gspassenc(Password);
string GsDecodedPass = gspassenc(GsEncodedPass);
Worked = (Password == GsDecodedPass);
// GsDecodedPass should equal the original Password
Console.WriteLine();
Console.WriteLine("GsPass Encoded: " + GsEncodedPass);
Console.WriteLine("GsPass Decoded: " + GsDecodedPass);
Console.WriteLine("GsEncode to GsDecode Worked? : " + Worked); // True
// Bas64 encode the encrypted password. Then decode the base64. B64_GsDecodedPass should equal
// the GsEncoded Password... But it doesn't for some reason!
string B64_GsEncodedPass = Base64Helper.EncodeString(GsEncodedPass);
string B64_GsDecodedPass = Base64Helper.DecodeString(B64_GsEncodedPass);
Worked = (B64_GsDecodedPass == GsEncodedPass);
// Print results
Console.WriteLine();
Console.WriteLine("Base64 Encoded GsPass: " + B64_GsEncodedPass);
Console.WriteLine("Base64 Decoded GsPass: " + B64_GsDecodedPass);
Console.WriteLine("Decoded == GS Encoded Pass? : " + Worked); // False
// Stop console from closing till we say so
Console.Read();
}
private static int gslame(int num)
{
int c = (num >> 16) & 0xffff;
int a = num & 0xffff;
c *= 0x41a7;
a *= 0x41a7;
a += ((c & 0x7fff) << 16);
if (a < 0)
{
a &= 0x7fffffff;
a++;
}
a += (c >> 15);
if (a < 0)
{
a &= 0x7fffffff;
a++;
}
return a;
}
private static string gspassenc(string pass)
{
int a = 0;
int num = 0x79707367; // gspy
int len = pass.Length;
char[] newPass = new char[len];
for (int i = 0; i < len; ++i)
{
num = gslame(num);
a = num % 0xFF;
newPass[i] = (char)(pass[i]^a);
}
return new String(newPass);
}
,其结果是:
任何帮助将非常感激!
UPDATE:这是我的Base64Helper类:
class Base64Helper
{
public static string DecodeString(string encoded)
{
return Encoding.ASCII.GetString(Convert.FromBase64String(encoded));
}
public static string EncodeString(string decoded)
{
return Convert.ToBase64String(Encoding.ASCII.GetBytes(decoded));
}
}
你能告诉你的Base64Helper.EncodeString和.DecodeString,谢谢(我想象你正在做字符串字节有[]转换) –
