| My new PIN code is my old PIN code Posted: 09 Dec 2018 08:04 AM PST Hopefully the right place for my question. Checked the rules and it seemed about right I lost my credit card recently, and ordered myself a replacement card. I got a letter through saying they had given me a new PIN, which I was annoyed about as I didn't want to have to remember a new number. But when I checked the letter, the new PIN they'd given me was the exact same as my old PIN. I'm not an expert in how these things work, but my understanding was that my PIN shouldn't be stored with my bank and that all they should have is the hash which was generated from my PIN. So the only explanation for this if all that's true is that my new random PIN just "luckily" landed on the same PIN as last time. The odds of this I think are 0.0001% But I guess it has to happen to someone. Am I right about this? Or have I misunderstood how PIN numbers are stored/generated [link] [comments]  |
| Monthly cryptography wishlist thread, December 2018 Posted: 09 Dec 2018 04:04 AM PST This is another installment in a series of monthly recurring cryptography wishlist threads. The purpose is to let people freely discuss what future developments they like to see in fields related to cryptography, including things like algorithms, cryptanalysis, software and hardware implementations, usable UX, protocols and more. So start posting what you'd like to see below! [link] [comments]  |
