How to encrypt string in c#...

[svr2112]

You can use following code for encryption

private string encryptString(string strToEncrypt)
{
System.Text.UTF8Encoding ue = new System.Text.UTF8Encoding();
byte[] bytes = ue.GetBytes(strToEncrypt);

// encrypt bytes
System.Security.Cryptography.MD5Crypto… der md5 = new System.Security.Cryptography.MD5CryptoSe… der();
byte[] hashBytes = md5.ComputeHash(bytes);

// Convert the encrypted bytes back to a string (base 16)
string hashString = "";

for(int i=0;i
{
hashString += Convert.ToString(hashBytes[i],16).PadLef…
}

return hashString.PadLeft(32,'0');
}

if u dont want the user to be able to see the querystring, just use action=POST instead of get in ur form tag (by default action=GET). this would hide the querystring from the user. or you could write functions in js to encrypt and decrypt the request url. (use any of the encryption algos.) but i'd still suggest using post action
