StrongKey CryptoEngine (SKCE) 2.0 is a "crypto swiss-army knife" server to perform cryptographic functions through webservices, while freeing up application developers to focus on business functionality. Its modules include:

- A FIDO Engine to support FIDO U2F key registrations/authentications;
- An Encryption Engine to encrypt/decrypt files using AES/TDES keys;
- Escrowing keys to on-premises key-management system (StrongAuth KeyAppliance);
- Integration to cloud-storage services (AWS S3, Azure and Eucalyptus Walrus);
- A Signing Engine to digitally sign documents, code, etc. with FIPS 140-2 HSM support; and
- An LDAP Engine for AD/LDAP integration for authorization decisions.

SKCE is battle-tested and in production at one of the largest e-commerce companies in the world, protecting more than 50M documents within the business process; see for the case-study.
