On Tuesday, Russian communication regulator Roskomnadzor indicated it may consider unblocking encrypted messaging app Telegram.
However, there's a rather significant catch: Telegram will have to hand over the keys to its users' encrypted chats.
"Our colleagues should apply to our appropriate authorities -- the Federal Security Service -- to interact with them, as required by Russian law, and to provide the data they are obliged to provide in Russia," Roskomnadzor deputy head Vadim Subbotin told the TASS news agency.
"Unlocking is possible, if they execute a court decision."
That's a non-starter. After all, the whole reason Telegram is blocked in Russia is its refusal to hand over those encryption keys.

"So far, this has never happened," the policy noted. "When it does, we will include it in a semiannual transparency report."
In a Telegram post on Tuesday -- the service provides public-facing channels as well as private messaging features -- founder Pavel Durov said the policy has been revised to belatedly comply with Europe's new General Data Protection Regulation (GDPR), and Telegram was "reserving the right" to comply with court orders.
"Regardless of whether we ever use this right, the measure should make Telegram less attractive for those who are engaged in sending out terrorist propaganda here," he noted.

Telegram has indeed been used as a messaging and propaganda medium by terrorists, notably those involved in ISIS.
So does Telegram's new policy indicate a thaw in its relations with the Russian authorities? Not according to Durov, who noted in his post that the Russian ban was not down to issues around terrorist suspects' IP addresses and phone numbers.
"Therefore, we continue our resistance," he said.
ZDNet has also asked Telegram for answers to these questions, but has received no reply as yet.
