Electronic Signature Apps FAQs

Q #1) What is an electronic signature?

Answer: Electronic signature is used to validate the identity of the person signing the document. An electronic signature can be typed, scanned, or generated by an e-signature application. Whatever type of e-signature is used, it must be attached to the document and stored on a computer.

Q #2) How to create an electronic signature?

Answer: You can use paid or free electronic signature software. The e-signature software uses a public key algorithm such as RSA to validate the integrity and authenticity of digital documents.

Q #3) Is an e-signature legally binding?

Answer: Electronic signatures that meet e-signature laws are granted the same legal status as handwritten signatures. As per the electronic signature laws in the US, an e-signature cannot be denied legal effect due to being in electronic format.

Documents signed using an electronic signature will be legally binding if there is an intent to sign and consent the parties to carry out business electronically.

Q #4) Is electronic signature software safe?

Answer: Electronic signature software is generally safe to sign documents. However, you must only use reliable e-signature software. Always read reviews before using specific software to sign your documents. Make sure that the e-signature software has an audit trace feature that traces who and when the documents were signed.

Q #5) What are the requirements for an electronic signature to be valid?

Answer: The Uniform Electronic Transactions Act (UETA) and Electronic Signatures and Records Act (ESRA) in the US have specified four requirements for an e-signature to be valid.

The requirements include (1) intent of the parties to sign; (2) consent disclosure to carry out business electronically; (3) record of electronic signature; and (4) electronic retention of the e-signature that must be reproduced whenever required.

How Does Electronic Signature Software Work

Electronic signature software uses algorithms to create hashes that identify users who signed the document. Hashes are in the form of numbers and characters. These are encrypted using Public Key Infrastructure (PKI) cryptography techniques.

The PKI encryption method involves two keys: a private and a public key. A person uses a private key generated by the e-signature software to sign electronic documents. The public key is readily available that anyone can use to validate the authenticity of the signed documents.

PKI enforces certain requirements for signing, renewing, and revoking digital keys and certificates. The algorithm also enforces additional requirements for security, such as a digital certificate like the Certificate Authority (CA) to authenticate electronically signed documents.

How to Select the Best Electronic Signature Software

The selection of the best digital signature software depends on the end user. Individuals can use signature software with a simple identity validation feature. On the other hand, businesses should select software not just with validation features, but also with workflow automation features that facilitate the submission, approval, and authentication of documents in bulk.

Branding is also an important feature that businesses should consider in an e-signature app. The software must allow customization of an electronic signature to match the corporate brand.

Other important features businesses should look for in an e-signature app include audit trails, encryption, and digital pen support.
