The Secure Hash Algorithm (SHA) is a family of cryptographic hashing functions developed by the National Institute of Standards and Technology (NIST) that ensures data integrity. The widely deployed SHA-1 outlived its ability to maintain security standards in the wake of stronger computational power. The industry and certificate authorities (CA) stopped issuing SHA-1 certificates in January 2016.
Push to Talk Plus client/application and server model utilizes secure communications. These sessions employ certificate authentication in which the application validates the authenticity of the server prior to establishing secure connections. To do so, both the application and the server must support a common secure hashing function.
By February 2018, all Verizon Push to Talk Plus servers will exclusively run with SHA-2 certificates. Since 2016, all updates to the Push to Talk Plus application have been bundled with the SHA-2 root only certificate file. Earlier versions* of the application will no longer function once the servers are completely switched to SHA-2 certificates, and therefore must be upgraded to include SHA-2 intermediate certificate bundles. Failure to update these older versions of the application by February 2018 will result in loss of service.
