Telegram Told to Give Encryption Keys to Russian Authorities

A top Russian court has told encrypted messaging app Telegram to share its encryption keys with state authorities.

Telegram, founded by Russian entrepreneur Pavel Durov, has been fighting an effort by the FSB, the state's security service formerly known as the KGB, which last year demanded that the company hand over its private encryption keys.

The company refused. On Tuesday, the country's supreme court upheld the demand.

Durov said in a tweet following the ruling: "Threats to block Telegram unless it gives up private data of its users won't bear fruit. Telegram will stand for freedom and privacy."
