The DL3 FE (FIPS Edition) sets a standard for encrypted portable storage. The DL3FE is the world's first external hard drive utilizing 2 pass, cascading encryption. The DL3 FE utilizes two independent crypto engines each using a random, unique 256 bit keys to encrypt your data first with 256 bit AES XTS mode algorithm and then sequentially with the 256 bit AES CBC mode algorithm. Each bit of stored data is encrypted twice with two independent keys which never leave your device. It is the first and only encrypted external hard drive to feature dual crypto processors. Every single bit of data at rest is double encrypted.
