DESCryptoServic eProvider used to encrypt a 64 length string, funny output

[Salman]

When I run the below method with a 64 character string as input such
as:

sr.Encrypt("123 456789012345678 901234567890123 456789012345678 901234567890444 4");

I get square boxes as my output, which means that some characters are
not being mapped in the encodings. What could be the problem?

Since my output is funny characters, my decrption will as a result
fail since it contiains invalid characters when I do a
FromBase64Strin g.

TIA
(Code Below)

byte1.GetLength (0));

strOutput = Encoding.ASCII. GetString(byte2 );
return strOutput;
}

You're trying to convert your byte2 array into ASCII even though it contains
non-ASCII code values. If you want to store the output of an arbitrary array
of bytes as an ASCII string you'll need to use Convert.ToBase6 4String() or
some other method.
