    The old fossile-fueled password car is dead (sold). I’m now driving 100% on electric passwords! :-D

  2. As predicted by one victim I talked to, before he chose to end his own life. This is exactly what he expected could happen at any point in the future. Go on hackers, read the UN human rights declaration, article 12:

    Reddit hashes passwords with bcrypt, but does not pre-hash. This means Reddit passwords longer than 72 characters are truncated. As a result, only passphrases using the EFF short #2 list are problematic:

    Apple stores don't require a captive portal anywhere in the world except China. I'm pretty sure they have a lot and pretty decent lawyers across the world.

    Also, if you have a GV100 (TITAN V, V100) the bcrypt cracking performance should be *doubled* but really only this exact chipset. So far this is only a theoretical value. I can't verify because I don't have this GPU for testing. Someone can verify?

    For those of you using a NV GPU with Volta or Turing chipset, listen up! We hacked our way into the post-48k GPU shared memory region. This improved bcrypt cracking performance by an average of 25%. For instance a GTX2080Ti improved from 42116 H/s to 54770 H/s

    Great to hear AFNIC are planning to move 6 ccTLDs and 3 gTLDs to P256 (algorithm 13) based keys. If you read the blog post, some more precise numbers: * Unsigned TLDs number 140 not 200 * SIgned TLDs number 1376 (not 1300) * TLDs with obsolete algorithms number 275 (not 300)

    Kommende foredrag om SHAKEN/STIR, en ny løsning som kan bidra til å redusere spoofede samtaler i telenettet. Et massivt problem i USA, mest kjent som «microsoft support» telefon i Norge. Og det er en løsning som visstnok få/ingen teleoperatører i Norge, Norden eller EU vurderer.
