Cybersecurity Showcase

The Security Lab & PGP Sandbox

Demonstrating functional asymmetric encryption, symmetric block ciphers, and digital envelope packaging. This production-grade laboratory is designed from scratch to simulate PGP (Pretty Good Privacy) pipelines, validating payload integrity and authenticating asymmetric keypairs in real-time.

MCA Cybersecurity Lab

Built by Harish N as an educational demonstration of standard cryptography modules. Plaintext packets undergo real bitwise encryption, base64 encoding, and SHA-256 integrity hashing into standard PGP ASCII Armor formatting.

Symmetric Shift Deterministic RSA CRC-24 Checksum

Module A: PGP Encryption

Pipeline Ready

Compresses, signs with SHA-256, encrypts under a dynamic session key, seals the session key with RSA, and outputs armored envelope text.

1. Plaintext Message

Encryption Debug Output

› Waiting for plaintext payload input...

2. Armored PGP Message Block Output

Module B: PGP Decryption

Auth Required

Parses the envelope, verifies CRC-24 checksum, authorizes Private Key, extracts session token, decrypts data, and checks SHA-256 integrity.

1. Input PGP Armored Block

Decryption Debug Output

› Waiting for armored PGP envelope payload...

2. Decrypted Plaintext Output Message

Dynamic Integrity Verification Test
Try altering a single character inside the Base64 section of the armored block input above, then hit decrypt. The pipeline will immediately alert you in the debug log with a red warning for CRC parity breach or SHA-256 tamper detection!
