Some chapters may have received a notice from PayPal concerning security changes.
All Proteon sites are compliant and there is no action necessary for the chapters.
Proteon upgraded all the sites last year in anticipation of this. Here is a little background on PayPal's actions.
Due to security concerns over advances in computing power, the industry is phasing out 1024-bit SSL certificates (G2) in favor of 2048-bit certificates (G5), and is moving towards a higher strength data encryption algorithm to secure data transmission, SHA-2 (256) over the older SHA-1 algorithm standard.
Since Chrome already deprecated support for SHA-1 by the end of 2015, and all support for SHA-1 will be deprecated by the end of 2016, they need to act soon to implement these changes.
PayPal will ensure that all SSL certificates meet the following standards:
Discontinue support for secure connections that require validation with the VeriSign G2 Root Certificate; only validate with the VeriSign G5 Root Certificate.
Use a stronger algorithm by upgrading from SHA-1 to SHA-2 (256).
To reiterate all Proteon sites are compliant and there is no action necessary for the chapters.
