The decryption key for the HSE cyber-attack is undergoing a detailed assessment to determine whether it's safe to use.
The Government insists no ransom was paid to the cyber criminals who hacked into the health service's network last week.
The Government says this decryption key arrived "unprompted" yesterday evening.
Justice Minister Heather Humphreys explains that the National Cyber Security Centre is examining the key.
The Government claims no ransom has or will be paid and that they didn't engage with criminals, so why did they hand over they key?
Cyber Experts say the criminals may have provided it, as they've annoyed the hacking community by drawing so much attention to how they operate.
Junior Minister Ossian Smyth says it doesn't mean the data won't be published on the dark web and that's why an injunction has been secured.
The Government says its priority is to ensure a speedy resumption of all health care services.
