X509 Certificate

This repository contains the means to create all kinds for misconfigured or invalid x509 certificates for testing purposes. Often, such tests are not done because the certificates eventually expire and someone would have to recreate the - admittedly complex - Public Key Infrastructure (PKI) to re-issue the test certificates.

Minimal certificate authority for self-signed certificates. Just a simple bash script with instructions on how to use it in the README.md.

presentation about verification of x509 certificates - what use cases to take into account and how to set up test resources

This project contains a presentation comparing analog (or physical) and digital identities

This is a presentation about all the things that need consideration when building a Certificate Authority (with OpenSSL). On push - the presentation is built via CI/CD.

A combination of multiple useful tools. Cryptographic: Hash, Encoding (Base64, HEX, ASCII), Bit operations, AES, Cipher, DES/3DES, RSA, Certificates, Password based key generation, TLV parser. Smart Card: ATA analysis, SIM related, GSMA RSP .22 LPA
