Chinese satellite sends 'hack-proof' message - BBC News

and if they use SHA-256 encoding you can crack it with a bitcoin mining rig like it is a normal bitcoin transaction since the rig is an ASIC processor designed specifically to decrypt SHA256

Also, normal cracking operation is the hash is captured by the recon team... they set up their analyzers like Airomon-ng with Airodump-ng which are tools that black hats and white hats use, if they are penetrating a Wifi. If they are cracking user log then they will set up wireshark with a MITM(Arp poisoning) scenario to eavesdrop on network traffic.

Once their net analysis captures a password hash, they will transfer it to the cracking team, who will run it through pyrit at a fixed installation with massive server capability to crack the password using a bruteforce.

Once the password is cracked they will log onto info systems and dump all data and then will use it in a manner consistent with their mission statement

That's going to be one tough cookie
