Is this a web application? What is source of signature? PFX or USB Tokens ? In India Individual Signatures are issued only in USB Tokens... – Bharat Vasant Mar 29 '21 at 07:48

Its a nodeJs WebApp . Trying to create key cryptographically (AES, RSA, SHA256) and embed the digital signature to a PDF (the data inside the PDF is constant). – Aiswarya Mar 29 '21 at 09:56

Refer: https://stackoverflow.com/a/55676351/9659885 wherein you would be able to use Signer.Digital Browser Extension on browser side. On server side you can use any PDF component or Library as you wish. – Bharat Vasant Mar 30 '21 at 05:24
