E-Signature Software and Apps – Review

Global Digital Signature Market Size Increase 2024 – 2030

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.
