+// Another implementation of the Rijndael cipher.
+// This is intended to be an easily usable library file.

+// This implementation works on 128 , 192 , 256 bit keys
+// and on 128 bit blocks
+//
+
+//
+// Example of usage:
+//
+//  // Input data
+//	unsigned char key[32];                       // The key
+//  initializeYour256BitKey();                   // Obviously initialized with sth
+//  const unsigned char * plainText = getYourPlainText(); // Your plain text
+//  int plainTextLen = strlen(plainText);        // Plain text length
+//
+//  // Encrypting
+//	Rijndael rin;
+//  unsigned char output[plainTextLen + 16];
+//
+//	rin.init(Rijndael::CBC,Rijndael::Encrypt,key,Rijndael::Key32Bytes);
+//  // It is a good idea to check the error code
+//	int len = rin.padEncrypt(plainText,len,output);
+//  if(len >= 0)useYourEncryptedText();
+//  else encryptError(len);
+//
+//  // Decrypting: we can reuse the same object
+//	unsigned char output2[len];
+//	rin.init(Rijndael::ECB,Rijndael::Decrypt,keyMaterial,Rijndael::Key32Bytes));
+//	len = rin.padDecrypt(output,len,output2);
+//  if(len >= 0)useYourDecryptedText();
+//  else decryptError(len);
