Cipher Suite Usage - Update

Scheduled for Jul 8, 00:00 - 00:15 MDT

Scheduled

Please note on Tuesday, July 8th, 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:

ECDHE-RSA-AES256-GCM-SHA384/TLS1.2, DTLS1.2
ECDHE-RSA-AES128-GCM-SHA256/TLS1.2, DTLS1.2

The unacceptable ciphers would be:

ECDHE-RSA-AES256-GCM-SHA384/TLS1.2, DTLS1.2
ECDHE-RSA-AES256-SHA384/TLS1.2, DTLS1.2
ECDHE-RSA-AES128-GCM-SHA256/TLS1.2, DTLS1.2
ECDHE-RSA-AES128-SHA256/TLS1.2, DTLS1.2

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.
