Support Ending for Early Versions of TLS – Frequently Asked Questions

Q: What is TLS?
A: TLS stands for Transport Layer Security. Websites use TLS protocol to encrypt data and provide communications security between two endpoints. Essentially, TLS helps keep sensitive material, like your payment information, safe while you’re using our site.

Q: Great! Why should I know about TLS?
A: Starting in the summer of 2017, ZAPP® and CaFE™ will only support TLS version 1.2. This ensures that we will continue to bring you a highly-secure website for processing credit card and PayPal transactions.

Q: Will my use of ZAPP®/CaFE™ be affected in any way?
A: If you are using an old browser that does not support TLS version 1.2, you will not be able to access ZAPP® or CaFE™. This will affect both the artist and administrator sites.

Q: How can I check if my browser supports TLS version 1.2?

Q: Which browsers are supported and compatible with TLS 1.2?
Once TLS 1.0 has been disabled on ZAPP® and CAFE™, a user with a browser that does not support TLS 1.2 will be unable to connect. These users will need to upgrade to a newer browser that supports TLS 1.2. The browsers below support TLS 1.1 and above:

  • Microsoft Internet Explorer 11 and above
  • Google Chrome 30 and above
  • Firefox 27 and above
  • Apple Safari 9

Browsers that have TLS 1.1 and 1.2 disabled by default will need to have TLS 1.1 and 1.2 manually enabled. The following configurations may require manual enablement of TLS 1.1 or 1.2:

  • Windows 7 users with IE 8, 9, and 10
  • Windows 8 users with IE 10
