Indeed, RIPEMD-160 was used. Downgrade to 1.25.9, creating a new volume, copy data and upgrade solved the problem. Thanks for the help, Mounir IDRASSI and Enigma2Illusion.
After upgrade of veracrypt 1.25.9 -> 1.26.7 on Ubuntu 20.04.6 LTS (Kernel: 5.15.0-86-generic x86_64), decryption of a veracrypt volume failed with "wrong password or not a veracrypt volume". After downgrade to 1.25.9, decryption worked again. Tested on a second machine (Linux Mint 20 Ulyana): Updated to 1.26.7, decryption stopped, too. I used builds from https://unit193.net/
Tested on different machines. On windows works as supposed, on Linux not. Same TB (60.6.1) and EM (2.0.10) versions...
Hi, don't know if it's an Enigmail or Thunderbird problem, but if I add the column "Enigmail" in the list, it is always empty. Described here: https://www.thunderbird-mail.de/forum/thread/81864-kennzeichnung-von-verschl%C3%BCsselten-nachrichten/#post444230
