In this video Graham explains how you can achieve "crypto-agility" by maintaining an up to date cryptography inventory.
Crypto Cartography: Mapping the Crypto in Applications
March 22, 2019
A first step of many cryptography projects - preparation for Cloud migration, crypto agility, or improving application security, is to map out the cryptography actually in use in an application. A naive approach would be to just review the source code and search for cryptographic calls. However, this is both time-consuming and error-prone...
Achieving 'Crypto Agility'
January 21, 2019
A recent NIST paper recommending which steps to take to prepare for the advent of quantum computers proposes that users of cryptography look to achieve 'crypto agility' as soon as possible. The idea was further expanded by Gartner in a recent research note, and now crops up regularly. It's sometimes described as 'crypto-agnosticism', but what does it mean, and how does one achieve it?
