  * @addtogroup encdec_module Encryption/decryption module
- * 
- * The Encryption/decryption module provides encryption/decryption functions. 
- * One can differtiate between symmetric and asymetric algorithms; the 
- * symmetric ones are mostly used for message confidentiality and the asymmetric 
- * ones for key exchange and message integrity.
- * Some symmetric algorithms provide different block cipher modes, mainly 
- * Electronic Code Book (ECB) which is used for short (64-bit) messages and 
- * Cipher Block Chaining (CBC) which provides the structure needed for longer 
- * messages. In addition the Cipher Feedback Mode (CFB-128) stream cipher mode
- * is implemented for specific algorithms.
  *
- * Sometimes the same functions are used for encryption and decryption.
