As of 7 August 2017, PayU will only support the below listed cipher and protocol combinations.
...
In addition, Perfect Forward Secrecy will also be implemented as well as support for TLS .
Please note that support for TLS 1.0 which will will be deprecated on on 30 June 2018.
It is highly recommended to test communication / integration against PayU's staging environment before 7 August 2017 in order to assure uninterrupted service.

Q&A:
What is a Cipher Suite?
A cipher suite is basically a complete set of methods (technically known as algorithms) needed to secure a network connection through SSL (Secure Sockets Layer) / TLS (Transport Layer Security).
