Shall I use SSL 3.0?

Follow
In view of the SSL 3.0 protocol security vulnerabilities, it is not supported by Viva Payments.
 
We recommend disabling SSL 3.0, especially on hosts directly interacting with Viva Payments and instead use Transport Layer Security (TLS). Be aware that based on all our traffic analysis reports, virtually all consumers interacting with our platform are using browsers which support TLS.
