Clarification on digital signatures

What is the difference between a digital signature and an e-signature? How does a digital signature relate to Public Key Infrastructure (PKI)? What algorithm does a digital signature use: Is it cryptography or another algorithm?


No difference. E-signature is the catchy marketing name the government put on digital signatures.

PKI provides the means of managing digital certificates. Digital certificates contain public keys for individuals or entities.

A digital signature uses a digital signature algorithm such as RSA or SHA1. Yes, it is a cryptographic algorithm.
