Abstract: A method of electronically signing a document includes initializing a user, including generating an asymmetric key pair including a private signing key and a public signing key, and storing the private signing key and the public signing key; and providing an electronic signature, including receiving document data corresponding to at least one selected portion of the document, binding the stored private signing key and the document data to create an electronic signature, and providing the electronic signature for a recipient.

Abstract: A cryptographic key split binder includes key split generators that generate cryptographic key splits from seed data and a key split randomizer for randomizing cryptographic key splits to produce a cryptographic key, and a process for forming cryptographic keys. Key split generators can include a random split generator for generating a random key split based on reference data, a token split generator for generating a token key split based on label data, a console split generator for generating a console key split based on maintenance data or a biometric split generator for generating a biometric key split based on biometric data. Any key split can further be based on static data, which can be updated. Label data can be read from a storage medium, and can include user authorization data. A cryptographic key can be, for example, a stream of symbols, at least one symbol block, or a key matrix.
