A Python CLI tool to facilitate certain Google Cloud KMS operational tasks, including Certificate Signing Request (CSR) signing using private keys hosted in Google Cloud KMS (HSM).

Parse and verify the X.509 family (X.509/CSR/CRL/PKCS#7/PKCS#12) into uniform records; drift, inventory, chain, revocation, and CABF/Mozilla compliance reports. A green check means it actually verified.

Python suite implementing NIST & FIPS cryptographic standards including Diffie-Hellman, RSA-PSS signatures, X.509 certificates, AES-GCM, and hybrid encryption.

A powerful bash script that creates SSL certificates with custom CA for development and testing. Interactive setup, multi-domain support, and multiple output formats in one simple tool.

Secure Java e-voting simulator providing authenticity, secrecy, and integrity via Bouncy Castle cryptographic primitives.

A secure console-based chat system implementing PKI, RSA, Diffie-Hellman, AES-128, and SHA-256 to achieve CIANR (Confidentiality, Integrity, Authenticity, Non-Repudiation). Features self-built CA, X.509 certificate validation, encrypted messaging, and session transcripts for non-repudiation.

Safely read certificate signing requests and X.509 certificates in Ruby; subject, SANs, key & signature hygiene, fingerprints, pluggable issuance policy. Zero dependencies.

Console-based PKI-enabled secure chat system in Python demonstrating cryptographic principles (CIANR): Confidentiality, Integrity, Authenticity, and Non-Repudiation. Features RSA/AES encryption, Diffie-Hellman key exchange, X.509 certificates, digital signatures, and MySQL-backed user authentication.

Generate, sign, and export SSL certs — CSR, keypair, chain — one .exe

Role-based PKI for issuing, storing and revoking X.509 certificates - Spring Boot + Angular, with CRL revocation, envelope-encrypted key storage and TOTP 2FA.

Manages Windows certificates with a small, no-nonsense GUI
