Invalid length for a Base-64 char array.
- by Code Sherpa
As the title says, I am getting:
Invalid length for a Base-64 char
array.
I have read about this problem on here and it seems that the
suggestion is to store ViewState in SQL if it is large. I am
using a wizard with a good deal of data collection so chances
are my ViewSate is large. But, before I turn to the "store-in-DB"
solution, maybe somebody can take a look and tell me if I have
other options?
I construct the email for delivery using the below method:
public void SendEmailAddressVerificationEmail(string userName, string to)
{
string msg = "Please click on the link below or paste it into a browser to verify your email account.<BR><BR>" +
"<a href=\"" + _configuration.RootURL + "Accounts/VerifyEmail.aspx?a=" +
userName.Encrypt("verify") + "\">" +
_configuration.RootURL + "Accounts/VerifyEmail.aspx?a=" +
userName.Encrypt("verify") + "</a>";
SendEmail(to, "", "", "Account created! Email verification required.", msg);
}
The Encrypt method looks like this:
public static string Encrypt(string clearText, string Password)
{
byte[] clearBytes = System.Text.Encoding.Unicode.GetBytes(clearText);
PasswordDeriveBytes pdb = new PasswordDeriveBytes(Password, new byte[] { 0x49, 0x76, 0x61, 0x6e, 0x20, 0x4d, 0x65, 0x64, 0x76, 0x65, 0x64, 0x65, 0x76 });
byte[] encryptedData = Encrypt(clearBytes, pdb.GetBytes(32), pdb.GetBytes(16));
return Convert.ToBase64String(encryptedData);
}
On the receiving end, the VerifyEmail.aspx.cs page has the line:
string username = Cryptography.Decrypt(_webContext.UserNameToVerify, "verify");
And the decrypt method looks like:
public static string Decrypt(string cipherText, string password)
{
**// THE ERROR IS THROWN HERE!!**
byte[] cipherBytes = Convert.FromBase64String(cipherText);
Can this error be remedied with a code fix or must I store ViewState in the database?
Thanks in advance.
