贴了片段:encodingCharset=“UTF-8”,这好像是JAVA的MD5加密的算法..但里面有一些看不明白。谢谢..急..

这个我都不知如何拿C#来写..我是初学的。
byte[] k_ipad = new byte[64];
byte[] k_opad = new byte[64];
byte[] keyb;
byte[] value;
try
{
keyb = Encoding.GetEncoding("UTF-8").GetBytes(aValue);
value = Encoding.GetEncoding("UTF-8").GetBytes(aKey);
}
catch
{
keyb = Encoding.Default.GetBytes(aValue);
value = Encoding.Default.GetBytes(aKey);
}
for (int i = keyb.Length; i < 64; i++)
{
k_ipad[i] = (byte)54;
k_opad[i] = (byte)92;
}
for (int i = 0; i < keyb.Length; i++)
{
k_ipad[i] = (byte)(keyb[i] ^ 0x36);
k_opad[i] = (byte)(keyb[i] ^ 0x5c); }
不知道对不对,但后面部分真不知道什么意思..主要是不知道JAVA版的什么意思
