What is SSL

It is a technology that encrypts the information passed over the Internet and realizes secure communication.

By encrypting the data, it prevents the leakage of important personal information such as the card number and password entered during online shopping.
Even if a malicious third party can intercept the data, it cannot be decrypted because it is converted by encryption.

SSL is an abbreviation for Secure Socket Layer, a protocol developed by Netscape in the United States that allows information to be encrypted and sent and received on the Internet.
The feature is that highly confidential information such as credit card information can be safely exchanged between the server and the client PC.

By introducing SSL to your site, you can eliminate the security concerns of visitors and buyers.

For example, customers who shop on the Internet (online shopping) have these concerns.

  • Isn't it possible that the personal information entered in the entry form will be intercepted by a third party ...
  • The credit card number used to purchase the product may be leaked...

By introducing SSL certificates, these concerns are eliminated collectively.

Even if it is eavesdropped or intercepted by a third party, the information is encrypted, so the contents cannot be analyzed.

Implement SSL to create a secure online store environment.
