Email
encryption is basically encryption and authentication of email messages. Your
messages would be protected form In short e-mail encryption can be described as
the authentication and encryption of e-mail messages, a process of protecting
messages from unintended recipients. However this is not common due to several
factors. Public-key- cryptography is being used as a new encryption process.
This allows users to include a public key which allows others use the key to
encrypt the message. Messages are encrypted to protect messages from
inquisitive eyes. Given below the procedure on how to encrypt a mail:
It
would be a bit expensive to go for technologies but it would be worth the pay.
It makes the encryption affordable as well as easy. Various tools come with
various policies but they help you to deliver encrypted email as per your
requirements. The tools automate the encryption
process and organizational mails can be sent among clients, individuals and
groups. It would also manage security and reporting policies.
It
would give you a secure messaging within business associates, partners,
individuals and customers. If you are
going for right tools then you would not need any other hardware or software.
In
most case when you send an email it would be sent as plain text through web
without encryption. Most of the servers use mail protocol which can support
encryption, though it is one in one. Even Gmail
chains encryption between its personal server and the recipient’s server.
It cannot be assured that the mail would be totally secured between these two
servers. While encrypting a message ensure that it reaches the area of interest
only.
Encryption
is done with the help of private key and public key. In order to encrypt the
message if you use a public key then a private key is required to decrypt it. The process follows:
If
you have to send message to people use public key. However you need to keep the
private key secret.
Again
if someone wants to send you a message, he or she has to use the public key to
encrypt the message. Since the private key is kept secret, it is only you who
can decode the messages.
