Cipher Suite Usage - Update

Scheduled for May 30, 00:00 - 01:00 MDT

Scheduled

Please note on Friday, May 30th, 2025, we will disable connections to our external endpoints that are not using the following acceptable ciphers, per Global Payments Cryptographic Protection Standards:

The acceptable ciphers to use will be:

TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256

The unacceptable ciphers would be:

TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256

Please work and engage with your technical teams to ensure these unacceptable ciphers are no longer being used by the disabled date.

We anticipate no impact for partners using software with an up-to-date cryptography suite.
