Use Any SOP Binary With SOP-Java and External-SOP
I just released another library named external-sop, which implements sop-java and allows the user to use any SOP CLI application of their choice from within their Java / Kotlin application!
Implementing Packet Sequence Validation using Pushdown Automata
In the previous blog post I discussed how a formal grammar can be transformed into a pushdown automaton in order to check if a sequence of packets or tokens is part of the language described by the grammar. In this post I will discuss how I implemented said automaton in Java in order to validate…
Using Pushdown Automata to verify Packet Sequences
As a software developer, most of my work day is spent working practically by coding and hacking away. Recently though I stumbled across an interesting problem which required another, more theoretical approach…
Creating a Web-of-Trust Implementation: Accessing Certificate Stores
I made progress towards a full WoT implementation. The current milestone entails integrating certificate stores more closely with the core API. More specifically, an implementation of the Shared PGP Certificate Directory.
Creating a Web-of-Trust Implementation: Certify Keys with PGPainless
Currently I am working on a Web-of-Trust implementation for the OpenPGP library PGPainless. Technically, the WoT consists of a graph where the nodes are OpenPGP keys (certificates) with User-IDs and the edges are signatures. In order to be able to create a WoT, users need to be able to sign other users certificates to create…
Europe Trip Journal – Entry 24 – 26: OpenPGP Email Summit
After quickly refreshing, I took the bus to the other end of Geneva to the offices of Proton (formerly Protonmail). They hosted the 6. OpenPGP Email Summit which I was going to attend. When I got to the building, I had to call the office upstairs and one member of the Proton team came down…
Europe Trip Journal – Entry 5: Bonsoir
This morning I extended my stay in La Rochelle for another day. The night was relatively quiet, since in my 6-bed dormitory only one other bed had been booked. So after a good night of sleep I went to get some breakfast and then straight to the reception to book another night.
Creating an OpenPGP Web-of-Trust Implementation – A Series
I am excited to announce that PGPainless will receive funding by NGI Assure to develop an implementation of the Web-of-Trust specification proposal! The Web-of-Trust (WoT) serves as an example of a decentralized authentication mechanism for OpenPGP.
PGPainless 1.0.0 Released!
Close to the end of 2021 I’m excited to announce the release of PGPainless version 1.0.0! I feel like it finally reached a state of sufficient maturity to be worthy of a major release with a “1” at the front.
A Simple OpenPGP API
In this post I demonstrate how easy it is to perform OpenPGP operations in your application by using the SOP API.
