StrongKey CryptoCabinet (SKCC) 2.0 is a FIDO-enabled (fidoalliance.org) web application built using Regulatory Compliant Cloud Computing (RC3) architecture (http://bit.ly/rc3infoq).
It encrypts files/objects of any type or size, and stores the ciphertext either to public/private clouds—AWS, Azure, Eucalyptus—or local/network drives, while keeping cryptographic keys safe and secure OUTSIDE the cloud.
CryptoCabinet leverages the StrongKey CryptoEngine (SKCE)—another FOSS on this site...
