Software Update: VeraCrypt 1.25.7

An update to version 1.25 of VeraCrypt has been released. VeraCrypt, a fork of TrueCrypt, is an open source encryption program that can encrypt entire hard drives or partitions and virtual volumes. VeraCrypt uses the original source code of TrueCrypt, but includes several security improvements. Volumes created with TrueCrypt can simply be opened and converted. In version 1.25 support for Windows 11 has been added, but at least Windows 10 is required. Support for Apple’s M1 and OpenBSD has also been added. In version 1.25.7 the following changes and improvements have also been made:
