Encrypting data, files and other types of documents is important, especially when sending them electronically over the internet. In order to achieve encryption, the most common method used is public key cryptography. This method uses a pair of digital keys in order to encrypt and decrypt data. One key is called the public key, which you share with anyone who wants to send you encrypted data. The other key is called the private key, which you use to decrypt the encrypted data you receive.
Public Key Cryptography Does Not Require a Secure Connection
The process involved when using public key cryptography is not that complicated. This method eliminates the need of having to use a secure connection, since the file, data or email message is already encrypted. The basic process involves creating the email, document or other data and enabling the encryption, often through a menu choice or pop-up option. Once encrypted, you simply send the file or message to the recipient.
