ASIO boss Mike Burgess says he may soon use powers to compel tech companies to cooperate with warrants and unlock encrypted chats to aid national security investigations.

The founder of encrypted messaging service Telegram has been detained in France as part of an investigation into a lack of moderation and criminal use of the platform.

Today, the National Institute of Standards and Technology (NIST) announced the first standardization of three cryptography schemes that are immune against the threat of quantum computers, known as post-quantum cryptography (PQC) schemes. With these standards, NIST is encouraging computer system administrators to transition as soon as possible.

August 31, 2021:AWS KMS is replacing the term customer master key (CMK) with AWS KMS key and KMS key. The concept has not changed. To prevent breaking changes, AWS KMS is keeping some variations of this term. More info. Typically, when you protect data in Amazon Simple Storage Service (Amazon S3), you use a combination […]

In general I try to limit this blog to posts that focus on generally-applicable techniques in cryptography. That is, I don't focus on the deeply wonky. But this post is going to be an exception. Today, I'm going to talk about a topic that most "typical" implementers don't -- and shouldn't -- think about. Specifically:…

Feb 17, 2025: This blog post references AWS CloudHSM Client SDK 3, which is no longer the recommended version. AWS recommends that you use the latest version, AWS CloudHSM Client SDK 5, which provides updated functionality and commands. We are currently working on an updated blog post for CloudHSM Client SDK 5. See the AWS […]
