Atomic Signatures™ combine hash values with symmetric encryption to create electronic cryptographic signatures. A patented method, it significantly decreases the processor load of signing at the server when compared with asymmetric methods, makes the signature process transparent to users, and does away with increasingly vulnerable digital certificates and keys. (For more about quantum computing threats to digital certificates and asymmetric keys, download the White Paper). Whether static documents, objects, form-based interactive documents, or meta-data, information is signed by a combination of technologies which at their base depend on hash values and symmetric keys. This combination can also include

• message digests of signed documents, data or objects,
• cycled message digests, enhanced by Lamport's methods,
• asymmetric cryptotransformations of message digests, or
• cryptographic artifacts of symmetric key operations without the use of message digests.

In addition, for those seeking only to sign PDF documents using conventional asymmetric objects, XKI™ web service methods are cheap and effective.
