Email encryption: Mailvelope

Between constant password breaches and the NSA looking in on everything you do, you’ve probably got privacy on the mind lately. If you’re looking for a little personal privacy in your communications with friends and loved ones, or you just want to trust that the documents you email to your accountant or client aren’t being intercepted and read, you’ll need to encrypt those messages. Most email is sent as plain text. This means that anyone can intercept email messages. To rescue ourselves from man in middle attack we must have to use email encryption. Mailvelope is a browser extension that allows exchanging encrypted emails following the OpenPGP encryption standard.

Email encryption
Email encryption refers to encryption of email messages, to protect the content from being read by any unauthorized recipients. By using Email encryption we can keep our data safe when we send our documents. By the use of email encryption technique any unauthorized person is unable to understand the content of our mail. Email encryption can rely on public-key cryptography, in which users can each publish a public key that others can use to encrypt messages to them, while keeping secret a private key they can use to decrypt such messages or to digitally encrypt and sign messages they send.

Mechanism of email encryption
Encrypted email is a way of keeping the content of your email safe from eavesdropping as it bounces around the internet. The most common type of encryption is OpenPGP (PGP is “Pretty Good Privacy”). It was created by Phil Zimmerman in 1991. We can perform hard drive encryption, file system encryption as well as attachment encryption. It’s basically based on Public Key cryptography which contains a public key and a private key.
Pretty Good Privacy is a popular program used to encrypt and decrypt e-mail over the Internet. It can also be used to send an encrypted digital signature that lets the receiver verify the sender’s identity and know that the message was not changed en route.
