It literally points out that the info is encrypted and that the only way to restore it is to use a a distinct decryption key. Regretfully, this is definitely true. The type of cryptography mechanism applied by W2tnk is still not appropriately examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is absolutely unique. It is difficult to bring back the files without the key available.
