Freelancer stores character files in standard ini file format. They may be encryped or in plain text. Freelancer will read both formats.

The first four bytes of an encrypted file are FLS1. The encryption algorithm is show here:

private static byte[] gene = { (byte)'G', (byte)'e', (byte)'n', (byte)'e' }; byte[] decrypt(byte[] buf) {

 if (buf.Length >= 4 && buf[0] == 'F' && buf[1] == 'L' && buf[2] == 'S' && buf[3] == '1')
 {
   byte[] dbuf = new byte[buf.Length - 4];
   for (int i = 4; i < buf.Length; i++)
   {
     int k = (gene[i % 4] + (i - 4)) % 256;
     dbuf[i - 4] = (byte)(buf[i] ^ (k | 0x80));
   }
   return dbuf;
 }
 return buf;
}
