For many people, email has become the most commonly used communication tool like telephone. In this case, we soon forgot that the email is not secure. Someone uses the protocol analyzer to capture and recombine the packets you send on the network to view the emails you send to the recipients. It may not be a big problem if you only send jokes or party invitations via email. If you are sending sensitive information, you may need to encrypt it.
Sensitive Information
Each person has different definitions of sensitive information. In my opinion, if you do not want anyone in the world to see your message, you should regard this information as sensitive information. This information may contain technical information related to your computer system, information about your ID card or financial information or any personal information, and information that may embarrass you.
Email encryption method
If you decide to encrypt your email information, the next step is to find the encryption method. You can use third-party products to encrypt email information, but if you use Microsoft Outlook software, you need a digital certificate before you can use outlook to encrypt your email information. This certificate is the key of an algorithm used to encrypt email information and its attachments. This certificate can also be used for digital signatures. Sign an email with a digital signature to tell your recipient that this email is indeed sent by you rather than by an impersonator. The digital signature also ensures that the email is not modified during sending.
Digital signatures do not seem important at first glance. However, digital signatures can protect you from spoofing. For example, some people have sent me some bad-spoken emails to my editors using fake email addresses. As I am not used to using electronic signatures, I cannot prove that these emails are fake. Fortunately, my editors are very familiar with my writing style and believe that those emails are not written by me. If these emails are sent to others, the results will be completely different.
So where can I get the certificate? We all like the email encryption certificates provided by wosign, which can be applied for free, buy.wosign.com
