A new interface, powerful security, and unique approach will put Panther Sleek at the top of the list for cryptography enthusiasts. Panther Sleek is a derivative of the original Panther software also by Tamalin. Both programs use the extremely secure advanced encryption standard to ensure total security of information in transit.
