Base64 Decoding

Hi All,

Could you please give me some guidelines on dealing with
Base64 encoded string.
The actual purpose is to decode Base64 Encoded string
and stream the data to a browser so that it can be viewed
in a web application

Not sure what exactly you are looking for. If you are finding a way to
decode a base64 string, use Convert.FromBas e64String()

public static string Base64Encode(st ring data) {
byte[] myBytes = Encoding.ASCII. GetBytes(data.T rim().ToCharArr ay());
return Convert.ToBase6 4String (myBytes);
}

public static string Base64Decode(st ring data) {
try {
return Encoding.ASCII. GetString (Convert.FromBa se64String (data.Trim()));
} catch {
// Invalid String!
return "";
}
}

I have a C App which uses openssl for Encoding and decoding which needs to be ported to java. The decoded text does not match between the C App and the java App. The size of the output itself is wrong. I think i am doing something basically wrong. pls help. Output is not the same as seen here because of special characters Output from C: is only 12 bytes long

I have encoded a string into Base64 for the purpose of encryption. I then later decrypted it and converted it back from Base64 the final string returns with four nothing characters. "pass" what the result should be "pass____ what the result is where each underline char is a nothing char. I am about to write a function that will remove the nothing chars butI would like to know what is causing the problem and simply avoid it

Hi , I am currently trying to implement base64 encoding and decoding scheme in C . Python has a module , base64 , that will do the encoding and decoding with ease . I am aware of OpenSSL having support for base64 encoding and decoding , but i will have to now implement both in C without using the openssl libraries . I was able to download a code w.r.t. base 64 encoding and decoding . I am attaching the code below .

I'm having a problem decoding an encrypted Base64 string (with a key). I am trying to encode and decode with a url friendly version. It works if I use them seperate but when I try to put them both in the same function it doesn't decrypt it right. function encrypt($string, $key) { $result = ; for($i=0; $i<strlen($string); $i++) { $char = substr($string, $i, 1); $keychar = substr($key, ($i % strlen($key))-1, 1);
