What is the ruling on establishing a server containing the cards of encrypted packages such as "Al-Jazeera Sports," "Showtime," and "ART," and providing a service to broadcast the decryption keys to subscribers for a fee?

The ruling on purchasing a server and trading in channel cards depends on their content. If they display forbidden matters such as music, immodest display (tabarruj), mixing of genders (ikhtilat), and movies, then it is not permissible to sell the cards or participate in "sharing," because that constitutes cooperation in sin and transgression. However, if they are free from forbidden matters, then there is no harm in that.
