چکیده
Different forms of encryption techniques are being used to ensure privacy of data transmitted over Internet. Digital signature which uses Public Key Encryption (PKE) ensures privacy of conversation, integrity of data, authenticity of sender and non-repudiation of sender. Several applications on desktops, mobiles and other devices use it to secure data of various applications, services and access to devices. Digital signature exists as a file on some storage device or is embedded in hardware devices. Digital signature certificates are digital signatures that are signed by some third party certifying authority. This paper describes working of digital signature through illustrations and explains various procedures and algorithms involved in signings the data through use of digital signature. It introduces an open source software tool that can be used to study processes, procedures and algorithms used in digital signatures. It also presents information about different types of digital signature certificates currently available, file formats used therein and programming support of digital signature in .NET languages. Further, it presents an excerpt of digital signature scenario in Indian Government. General Terms Encryption, Hashing, PAIN, Public Key Encryption, PKI, Authentication, Privacy, Information Security, PKI in India.
