Email encryption: enhance security of mail over net Indian School of Ethical Hacking (#ISOEH) : @ isoeh/ People mostly use emails over internet.. However few ever consider the level of security of the mails over the internet or whether its securely travels over the network...Today we will discuss a popular service for encrypting emails over the internet with enhanced privacy and security courtesy of a popular programme called PGP.. (PGP) or #PrettyGoodPrivacy , the brainchild of Phil Zimmermann way back in 1991, is a data encrypting program for cryptographic privacy over the internet. Its usage is encryption of e-mails but can also be extended to files and disk encryption for enhanced security in the #web. #PGP working design method:- PGPs encryption has a multilayer combination of #hashing, #cryptography, and the essential public-key cryptography all resting on the base of withstanding algorithms. PGP offers the facility to send- receive emails with increased confidentially with key- encryption algorithms which are 1 session keys. The message and its session key are sent to the receiver. Messages are encrypted using encryption algorithms and “use once” keys/ session keys. Message integrity property and digital signatures are used to find out whether the contents of a file being sent over the net are modified and whether packets are lost in the transmit, as a result PGP creates a digital signature for the message with specific algorithms by computing hashes and the resulting digital signature providing a means of high security mechanism. Versatility of PGP is not only limited to #emails, it can also cater to #data storage on disk files. Its decryption is used to detect whether a message has been altered since it was completed (the message integrity property) and the proof of a legitimate sender. PGP encryption applications are now extended to include disk encryption, system security, file transfer and most important server security.
