: The Concept Of Email Encryption
When the sender sends the particular message to the intended party, the public key is required for the initial encryption of the message sent and later the private key is required for the decryption of the encrypted message to view the actual contents from the source. This private key will be shared only between the sender and the receiver whereas the public key might be with many people, who might not be the actual intended receiver for the particular message. This concept of email encryption takes utmost importance in the years to come, as a person no longer has to key in his login and password to take a print out of his bank documents or some other transaction bill, but directly the messages can be transferred between the receiver and the sender with the digital signature of the sender.
The main reason for ‘encrypting’ the email is to ensure the ‘security’ of the communication over the open medium of transfer. This process makes sure that the message is received from the authenticated source only and is been delivered without any tampering, in the sense that, nobody has opened the mail and changed the contents of the same. The whole process of electronic signature and the digital signature along with the digital certificate process gives a total guarantee that the whole medium is ‘secure’ without any chance of intruders gaining access to the message content. The concept of email encryption involves two different types of key, namely private key and the public key for encrypting and decrypting the email message.
