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.

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
