for those of you waiting on the new certificate file, you can get it
here.
there is no charge for this file, although you will probably need to create an account on my site.
this file has all of the latest certificates as stated in the authorize.net knowledgebase articles.
i have tested this file on 2 live sites located in the US with zero problems. in addition to having run cursory tests, those 2 sites are both now using this new certificate file in production environments with no ill effect.
for now, i know this new file works in the environments i have tested. when authorize.net makes the changeover on October 23rd and 24th, 2024 will be the real test.
i will be closely monitoring the situation at that time, so that users of this module can continue using it hopefully uninterrupted.
best.
