Information is indeed clear & systematic but still I have some query. Could you please elucidate more on what exactly is the process of affixing digital signature. Other than just generating hash of the message and attaching private key; whats the criteria for attaching the signature to message? Should it be appended in the same document of message or can it be attached separately?
Thanks. You asked “whats the criteria for attaching the signature” – its actually appended to documents that require signature of authorised persons.
For example signature of Director in Company Documents required for filing with ROC. Since these are e-documents, the signature has to be ‘digital’. When one appends the Digital Signature to the documents – the document “freezes” ie. no change can be done to the document. If changes are done, then the e-document either gives error or the digital signature gets removed automatically – therefore signifying that the document is not authentic.
Similarly, now a days Digital Signatures are also used in filing with Income Tax Returns, and also other places as specified by Govt of India.
