The concept of digital signature and encryption
In the modern technical age every organization whether small or large is based on information technology. Information technology is the building block of every successful organization. The companies are rapidly shifting to online business for the sake of enhanced interaction with the customer and clients. Hence, security has become an integral issue. This further highlights the need of digital signature and encryption. The concern is to understand the concept of sending encrypted mails or other documents that can be validated with the e-signature. For using a digital autograph it is must to have a digital id which is known as digital certificate.
A digital certificate performs two functions. One is to put an electronic seal on any document. It will confirm that it will remain in the state as it was sent and that there has not been done any kind of alteration in it. A digital id is composed of two keys private and public key. The private key would be kept private where public key can be sent to everyone. The keys are in fact the documents which contain random letters and numbers but along with the algorithm the numbers show unique property. Once a document is run through algorithm with public key the document obtained will be encrypted. When it is encrypted it cannot be decrypted, for that one requires the private key.
On the other hand if file is run through algorithm with private key, the user will obtain the original document. If private key is not kept private then hackers can create one’s sign without the consent of the person. Next is how companies put electronic seal on the document is a completely different procedure than that in which the signatures are scanned and then pasted on the mails or documents. The process is useful in number of ways. It ensures that the file has been sent originally by a known person. It had not been modified and nobody else can read it.
It is necessary in case when a company puts some software on site. The users download this software and they want to be sure that the file they are going to download in their system is a trusted file and not a virus. It is when the use of digital signature comes into knowledge. Another significant innovation in this field is sharepoint. The digital signature sharepoint is a solution which improves the capabilities of e-sign. Sharepoint helps user to even sign pdf files, record and lists located centrally on the server of sharepoint. It therefore saves much on the cost integrated to the manual procedures. It further helps in streamlining of the processes, enhanced efficiency and association.
The digital signature sharepoint increases the profitability of the companies who have already invested for this automation of the business operations. It is useful to run business in a smooth manner. The digital signatures keep the work electronic from beginning till end especially in case of workflow looking for approvals. It is an effective approach to assist the society to move from paper work to digital. The encryption ensures only the sender and recipient can view the message, e-sign is the method to authenticate it that it has been sent by the sender only.
About: – An organizations operation is mainly based on exchange of confidential information over internet. Thus to ensure the security of the information is a must. These needs can only be served through digital signature and encryption.
