"We also know that end-to-end encryption services like WhatsApp, are being used by paedophiles", Home Secretary Amber Rudd told party activists in the northern English city of Manchester. A Home Office spokesman confirmed the proposed law change, although there is no timeframe attached to the plan as yet.
"Currently the power applies only to online material that has been downloaded and stored on the offender's computer, is saved on a separate device or printed off as a hard copy", explains The Guardian.
She criticized technology firms for developing encrypted software that has prevented authorities from reading terrorists' and criminals' messages.
The new law will extend an existing ban on downloading and possessing the content on a PC to repeatedly watching it through sites like YouTube.
Though there are now no guidelines as to what counts as a corrosive substance other than the warning sign on the bottles, it is likely to include products commonly sold in convenience stores such as bleach, drain unblocker and sink cleaner.
The blast came as the Government's former terror chief David Anderson QC warned that Governments were in an "arms race" with terrorists online.
Rudd is expected to tell the Conservative Party Conference on Tuesday that those found guilty of repeatedly viewing extremist material such as bomb-making instructions and far-right propaganda could now face lengthy jail terms.
In addition, a defense of "reasonable excuse" will apply to academics, journalists or others with appropriate reasons to view the terrorist content.
New laws will be introduced that could see consumers of terrorist content imprisoned for up to 15 years.
"I don't need to understand how encryption works to understand how it's helping the criminals".
"I call on you with urgency, to bring forward technology solutions to rid your platforms of this vile terrorist material that plays such a key role in radicalisation", she said.
Rudd said: "Acid attacks are absolutely revolting".
Speaking at a Spectator event, Rudd said: "It's so easy to be patronised in this business".
"There are other ways I can't talk about which we think they can help us more without necessarily entering into end-to-end encryption". We will take advice from other people.
