In the age of digital technology, email encryption is becoming a popular choice to aid in online protection. Using a digital signature mechanism, emails are encrypted by the sender and decrypted by the recipient. Important information that should be encrypted when emailed includes confidential, financial, medical, tax, and personal. On top of being easy to use, email encryption is advantageous to both senders and recipients because it prevents cyber attacks, protects against hackers, and stops companies from using, selling, and storing data. The next time you are sending important information online, make sure you are using email encryption.
