A system is described to authorize a transaction using blockchain technology. For example, a transaction authorization system comprises a point of sale (POS) device, a mobile device, and a payment blockchain. The POS device can initiate a transaction by scanning one or more items to be purchased and generating a code comprising a transaction identifier and a total cost of the one or more items. The mobile device can receive the code and can generate a token comprising the transaction identifier, total cost, a selected payment method identifier, and a value that can identify an account of a person associated with the mobile device. The token is sent to a payment blockchain to authorize the transaction.

Described herein are methods and systems for updating digital certificates on a computer and testing to confirm that the update was performed correctly. The testing may involve confirming that a server's common name (CN) and/or a server's subject alternative name (SAN) matches the domain name server (DNS) name utilized to access the server, confirming that, for all the certificates sent in chain, each certificate's expiration date is less than or equal to the expiration date of that certificate's parent certificate, confirming that the certificates' authority key identifier (AKI), subject key identifier (SKI), and/or authority information access (AIA) are in compliance, and comparing available cipher suites to a list of pre-approved cipher suites.
