Security is a top priority for YayPay, and to be able to maintain it, sometimes we need to make some changes that are not compatible with your current implementation. This time we are going to update TLSv1.2 ciphers to the most secure ones.

Previously used ciphers: 

TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (secp256r1)
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 (secp256r1)
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (secp256r1)
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (secp256r1)
TLS_RSA_WITH_AES_128_GCM_SHA256 (rsa 2048)
TLS_RSA_WITH_AES_128_CBC_SHA256 (rsa 2048)
TLS_RSA_WITH_AES_256_GCM_SHA384 (rsa 2048)
TLS_RSA_WITH_AES_256_CBC_SHA256 (rsa 2048)

New ones will be enabled: 

TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (secp256r1)
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (secp256r1)

To ensure that your integration supports them you can use https://developer.yaypay.com/api/v1/ instance where those changes are already applied.
