  • With regards to extracting the private key from the public key, to my knowledge there is shors algorithm that runs in polynomial time on a quantum computer that solves integer factorisation.

    Solve integer factorisation in P and you break RSA in P. I believe there are similar P algorithms that run on quantum computers for the discrete logarithm problem and elliptic curve discrete logarithm problem.

    In this sense, if you scale quantum computers resources enough you break modern asymmetric cryptography.

    With regards to breaking AES: Quantum computers halve the security. So 256 bit security goes to 128 bits. Still secure.

    AES 128 goes to 64 bits of security. Hmmm maybe not secure anymore. Have a read of post quantum cryptography and shors algorithm to see what im on about

    EDIT: added important details

    Edit 2: so so many typos





  • There is an end to end encrypted feature, with a 6 digit pin to decrypt the keys I believe. a 6 digit pin isnt the most secure, but its better then nothing for typical conversations.

    Annoyingly there is a feature that u can summarise texts with using AI, which ofc breaks privacy, but u can turn off message sharing (meaning you and the other person can no longer do that)

    A few glaring alarm bells around privacy on messenger, but again, better then nothing.





  • It depends on the evidence for the accusation just like anything else. I admit, for most accusations I don’t have time so just move on. For more serious accusations, I would think about it more whether its true.

    Sometimes the US makes shit up, sometimes it doesn’t. Same with China. I just have to take the time to determine if the evidence is sound, at least in principle.

    I don’t know those terms tbh because Im just some pleb. i would welcome some simple explanation of it.

    Wikipedia asserts “300 to 2700” dead, with the CCP asserted toll (according to wikipedia) being 241. That isn’t a peaceful dispersion, and, while not 10,000 people, is still a massacre.

    I just don’t understand how events like this doesn’t substantially taint your image of them, in the same sense the stolen generation policies (for my country, Australia) are massive stains on my countries’ histories that we havent fully contented with.

    But trying to relate it to what I my original comment, I worry about denials of mistakes that countries have made, results in failing to see their current mistakes. In particular aswell, seeing what would normally be considered a grave immoraility, to be seen in a much more positive light because its anti western imperialism.

    What I am saying aswell, is this also distorts the truth of events or facts, in a similar manner to an average western citizen’s truth because of their aversion to china.

    Name one major western critic of china you agree with.

    I’ll name a critic of the US: the cuba embargo for the past 70 has been a major disaster, and any deaths from economic collapse isnt due to cuba’s socialism, it is instead because of the US.

    Do that, I’ll be far more willing to believe you.
