GBDE

GBDE stands for "GEOM Block Device Encryption." It is a disk encryption framework used in FreeBSD, an operating system that is a member of the Unix family. GBDE allows users to encrypt whole disk partitions or filesystems, providing a way to secure data at rest. The primary features of GBDE include: 1. **Transparent Encryption:** Data is encrypted and decrypted automatically as it is read from and written to the disk, providing seamless integration with the filesystem.
