Secure Code Signing — Open-Source PKI Cryptographic Tool | ST6051CEM Practical Cryptography

This video demonstrates Secure Code Signing, an open-source Public Key Infrastructure (PKI) tool developed as part of the ST6051CEM Practical Cryptography coursework at Softwarica College.

The tool implements real-world cryptographic operations including:
- RSA key generation (2048 / 3072 / 4096-bit)
- Digital file signing using RSA-PSS + SHA-256
- Signature verification with tamper detection
- Hybrid encryption using AES-256-GCM + RSA-OAEP
- X.509 self-signed certificate generation
- PKCS#12 keystore export
- Replay attack prevention using nonce + timestamp
- Forward secrecy via ephemeral ECDH key exchange
- MITM prevention via certificate fingerprint pinning
- Full audit logging and admin panel
