An electronic signature is composed of electronic data and leaves no graphic representation on the document. Electronic signatures’ validity and probative force lie in the digital data incorporated into the document, which guarantee its integrity and the signatory’s identity. This is done through the issuance of:
(1) A digital certificate that proves that the signatory’s identity has been verified; and
(2) A unique fingerprint of the file that ensures that the document has not been modified since it was signed.
