唔好再喺網上裸跑

This attempt was soon demolished by other security researchers: the worst possible cryptosystem (using backdoored random number generators, worst-possible hashing functions, and involves hoping and praying that no adversaries would attack it) was counterproposed and presented in the same framework as Telegram’s crypto cracking contest (https://web.archive.org/web/20171213214126/https://moxie.org/blog/telegram-crypto-challenge/). Borrowing Telegram’s logic, the results of this contest “proved” this broken protocol’s “impenetrable security”, but in reality, “all it proves is that contests like these are tools in the service of snake oil.”
This is available at the disposal of the users in addition to the randomly-generated, 30-character password.
再講,其實backup (export as database) 係個 feature, not a limitation. 我諗多數messages 都唔需要被backup, 如果有紀念價值您可以安全地 backup to Standard Notes, etc. With Telegram 你之不過係transfer trust from a cloud server to another cloud server.
多數其他messaging apps都會直接save落 Internal Storage 或雲端儲存度, Signal 則唔會, 除非你explicitly咁做.
