DiskCryptor – Open-source full disk encryption solution

DiskCryptor is a free and open-source full-disk encryption solution for Windows, developed by Xanasoft (DavidXanatos) from Austria, the creator of Sandboxie. It can encrypt entire hard drives, individual partitions, or external storage devices. It was originally developed as a free alternative to DriveCrypt Plus Pack (developed by SecurStar) and PGP WDE (Whole Disk Encryption, developed by Symantec). The latter two have long stopped development, while it is constantly being updated and maintained by a team of developers, ensuring that it stays secure against any potential vulnerabilities.
