I have several exports of telegram data and I would like to calculate the md5 and sha256 hash of all files but it only calculates those in the root directory $ md5sum `ls` > hash.md5 md5sum: chats: Is a directory…
The current phpmyadmin tar download SHA256 hash does not match the download site value. The published hash for ver 4.9.3 is f75c5e11b076176436653c6138d8185b0351b02a1bf8c5069ec8d0af254911df but I get this : downloads % shasum -a 256 phpMyAdmin-4.9.3-english.tar 514219cdf85819748e5f89584ccb5e0d181c27262f7da8950918133706d3d8fe. Unfortunately the tar unpacked automatically. Do…
After seeing that default passwords generated by phpMyAdmin used mysql_native_password and therefore hashes didn't changed when equal passwords where used, I updated one user's password and set the hashing to SHA256. When I tried to login again using the setted…
I'm doing some URL verification between a Shopify site and my app. On Shopify, in a .liquid file, I'm creating an HMAC value using Shopify's built in hmac_sha256 string filter. I'm using a secret key and a Twitch user ID…
