Predominance of Digital Signature

Centuries back the way of reaching to a mutual agreement was by signing contracts using several physical seal methods. As technology evolved the signing agreements become digital, this made the process more secure and safe. The idea of digital signature was a contribution by Ronald Rivest, Len Adleman and Adi Shamir by their invention of RSA algorithm on 1977 which was the earliest digital signature method. The method of digital signatures were accepted legally up in court and have equal acceptance as same as that of a normal signature in a document. A digital signature certificate is represented using a digital key. This digital key is provided by the certifying authority which helps to verify the credentials of a person which helps to identify that particular person. These signatures are generated using public key encryption method. The major details included in a digital signature certificate is the user’s name, email, pin code, country and the date in which certificate issued and the certifying authorities name. The main benefits of digital signature include reduced cost and time, authenticity of the documents and integrity of the data. The digital signature certificate can be categorised into class 1, class 2 and class 3 certificates based on the type of applicant and the scheme of using this certificate. The maximum duration for which a digital signature is issued may vary from one to two years. These certificates are considered as genuine document in legal deeds. Digital signature maintains the authenticity and privacy of the individual person’s information.
