Base64 - bibliothèque pour MetaTrader 4

Base64 encoding was developed to provide the possibility of transferring binary data through transport channels that are not purely 8-bit, like the message body. The encoded data consumes about 33% less volume as compared to the original data. The encoding is often used for a simple encryption of data.

The library consists of two functions:

• void Base64Encode(string in,string &out) The encoding of the input entry "in" and placing the result to the "out"
  
• void Base64Decode(string in,string &out) The decoding of the input entry "in" and placing the result to the "out"

An example of usage:

#include "..\libraries\Base64.mq4"
void start()
  {
   string original="Hello world!";
   string result="",restored="";
//----
   Print("Original: ",original);
   Base64Encode(original,result);
   Print("Encoded : ",result);
   Base64Decode(result,restored);
   Print("Restored: ",restored);
//----
  }

Results:

Original: Hello world!
Encoded : SGVsbG8gd29ybGQh
Restored: Hello world!
