The method involves encrypting an initial digital content (10) e.g. video file, by an application of an encryption algorithm that is defined by an encryption key. The encrypted digital content (14A, 14B) are transmitted toward a receiving terminal. The encrypted digital content are decrypted by an application of a decrypting algorithm defined by a specific decryption key for generating a decrypted digital content (16). Independent claims are also included for the following: (1) a method for decrypting a digital content (2) a device for decrypting a digital content, comprising a storage unit (3) a computer program comprising a set of software instructions for an application of a decrypting algorithm (4) a computer readable data medium comprising a storage unit.
