How to eSign a document: electronic signature licitness for Public Relations in Mexico

- [Instructor] How do eSignatures work? Legally binding eSignatures work through using a digital signature system, by using public key infrastructure, PKI, a system that enables the secure management of electronic digital signatures by creating a pair of keys, a private key and a public key. The private, as its name suggests is not visible to others and is only used by the signatory of the document. The public key is shared with anyone who needs to validate the authenticity of the eSignature. PKI also ensures additional requirements, such as certificate authority are met, which is governed by organizations that are entrusted to maintain key security integrity. When a signatory provides an electronic signature, a cryptographic hash is created for the form or document, which serves as a unique digital fingerprint. The sender's private key then takes the cryptographic hash and encrypts it, then stores it in a secure HSM box. Using the sender's public key certificate, the recipient is able to decrypt the encrypted hash. On the recipient's end, a new cryptographic hash is generated. The two hashes are compared to validate authenticity and demonstrate that no tampering has taken place. Learn more at lightico.com.
