What is the difference between an eSignature and digital signature?
Both electronic signature (commonly known as eSignature) and digital signature are different methods of online signatures. Sometimes electronic and digital signatures are used interchangeably, however, there is a subtle difference between the two. 
eSignature is a generic term for any signature transmitted electronically. It is used only to verify a document i.e. to recognize the identity and provide consent via a symbol, image or process attached to the message or document. Though electronic signature is legally binding, the validation of the electronic signature is not performed by any trusted certificate authorities.
