1. A computer-implemented method for electronically signing an electronically stored document that includes document content, comprising the steps of: providing at least a first user and a second user remote access to the electronically stored document; applying, by one or more processors, a first electronic signature to the electronically stored document to produce an initial signed version of the electronically stored document, wherein the first electronic signature includes information that associates the first electronic signature with the initial signed version of the electronically stored document, the first electronic signature verifies integrity of the document content of the initial signed version of the electronically stored document, and the first electronic signature includes a first cryptographic component; subsequent to applying the first electronic signature to the electronically stored document, modifying, by the one or more processors, the document content of the initial signed version of the electronically stored document thereby producing a first revision of the electronically stored document; subsequent to modifying the initial signed version of the electronically stored document, applying, by the one or more processors, a second electronic signature to the first revision of the electronically stored document, wherein the second electronic signature includes information that associates the second electronic signature with the first revision of the electronically stored document, the second electronic signature verifies integrity of the document content the first revision of the electronically stored document, and the second electronic signature includes a second cryptographic component; and generating a revision history of the electronically stored document, wherein the revision history associates the first electronic signature with the initial signed version of the electronically stored document and associates at least the second electronic signature with the first revision of the first electronically stored document.
