SCSI Tape Encryption Manager - stenc (formerly on https://sourceforge.net/projects/stenc/)

Stenc

SCSI Tape Encryption Manager - Manages hardware encryption on LTO tape drives (starting with generation 4). Program should work on any other SCSI security protocol (SSP) capable tape drives. Supports key change auditing and key descriptors (uKAD).

Features

• SCSI hardware-based encryption management
• Supports Linux and FreeBSD
• Supports most SSP compliant devices, such as LTO-4 tape drives
• Key change audit logging
• AES Encryption
• Key Descriptor Management

Get the source code and compile

git clone https://github.com/scsitape/stenc.git
cd stenc/
autoreconf --install
./autogen.sh && ./configure  
make check     # optionally run the catch testing framework
make

Usage example

$ stenc -f /dev/nst0
Status for /dev/nst0 (TANDBERG LTO-6 HH 3579)
