A battle-tested explanation of why tracing is a very useful technique you can benefit from in your projects. A story from the trenches of implementing distributed tracing in our Acra data security suite.

We tried out and described a few approaches to reducing the size of Docker images for the components of our database encryption suite Acra. As a result, we found a way to reduce the container size by roughly 62 times.

Best cases of boring technical debt are understood when reflected properly. This post addresses a simple one: inelegant flags in core C library ended up breaking Python tests. This is no small case to us: tests breaking sometimes might end up in things seeming to work, but not really working. Not something you can afford yourself when you're doing cryptography, do you?

Investigating memory leaks can be fun, sometimes. Sometimes it might even teach you a few lessons in how the language you know and like actually works.

This post summarizes our experiences of testing Secure Comparator as an authentication mechanism for HTTP.
While we were planning, designing and implementing Comparator, real infrastructure in which it has to function (letting Toughbase instances without shared trust to be able to exchange records and request personal data safely) was very far from being ready, but we wanted to understand how good it was for some practical applications. So we chose the obvious - seeing how SC could work as HTTP authentication mechanism.

This blog post features infographic on how to choose crypto when developing iOS apps. It's always useful to put tool choice in context of causes (goals) and effects. This is what we've tried to do in this post.
