Stenc
-----

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

Features
--------

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