Does the CKS use symmetric or asymmetric key encryption?

When customers send with the Virtru CKS, Virtru employs a combination of both symmetric and asymmetric key encryption.  Symmetric keys are used to encrypt the data itself, just as Virtru would normally do without the CKS installed.  The CKS re-encrypts this already encrypted content with two sets of asymmetric keys – one that comes from the sender’s client and one that goes to the recipient’s client.
