Are you getting a message about the Security Certificate when accessing online banking through Google Chrome?

  • Why are you seeing that message when you connect to

    1. That has a valid certificate, that the certificate has been verified by a third party and that your connection is encrypted and secure.
    2. It is also telling you that the site uses the SHA-1 algorithm as part of the encryption mechanism. This is happening because Google Chrome now identifies when a website uses the SHA1 algorithm for secure communications. 
  • What is SHA-1?

    SHA-1 is one of a set of encryption algorithms used to secure your connection with An industry effort to migrate from SHA-1 to the more secure SHA-2 is underway, Google is leading this change and has started to highlight the use of SHA-1 in newer versions of Chrome. This explains why you are seeing this message now. Other browsers will follow over the coming months. 

  • What is AIB doing in response?

    AIB is currently updating its systems to support the SHA-2 algorithm within its online channels. 


    After this is completed you will no longer see this message and your communication with will use SHA-2.
