Cryptography Support for Encryption, RSA, AES and Security Coursework

From ancient ciphers to post‑quantum – we assist with every layer of cryptography.

🔐 Symmetric Encryption

Block Ciphers – AES (128/192/256), DES/3DES, Blowfish, Twofish; modes: ECB, CBC, CTR, GCM.
Stream Ciphers – ChaCha20, RC4 (weaknesses), Salsa20.
Key Management – Key derivation functions (PBKDF2, bcrypt, Argon2), key wrapping.

🔑 Asymmetric (Public Key) Encryption

RSA – Key generation, encryption/decryption, padding (OAEP), versus textbook RSA.
Elliptic Curve Cryptography (ECC) – Curve secp256k1, NIST P‑256; ECDH, ECDSA.
Diffie‑Hellman (DH/ECDH) – Key exchange, ephemeral vs. static, perfect forward secrecy.

🌀 Hash Functions & Digital Signatures

Hash Algorithms – MD5 (broken), SHA‑1 (deprecated), SHA‑2 (224/256/384/512), SHA‑3, BLAKE2.
Message Authentication Codes (MAC) – HMAC, CMAC, GMAC.
Digital Signatures – RSA‑PSS, ECDSA, Ed25519; hash‑then‑sign paradigm.

🏛 PKI & Certificate Management

X.509 Certificates – Structure, extensions (SubjectAltName), validity periods, and revocation (CRL, OCSP).
Certification Authorities (CAs) – Root vs. intermediate, trust chains, Web PKI, letsencrypt.
Self‑signed Certificates – Use cases, generation, and limitations.

🔌 Cryptographic Protocols

TLS/SSL – Full handshake (1.2 vs 1.3), cipher suites, extensions (SNI, ALPN), attacks (POODLE, BEAST, Heartbleed).
IPsec – Transport/tunnel mode, IKE (Internet Key Exchange), ESP/AH, security associations.
SSH – Key exchange, user authentication (password, public key), port forwarding.
PGP/GPG – Web of trust, mixed encryption (hybrid), key signing.

🧮 Mathematical Foundations

Prime Numbers & Factoring – Primality testing (Miller–Rabin), RSA factoring challenges.
Elliptic Curves – Group operations, scalar multiplication, discrete log problem.

🛡️ More areas we excel in

Post‑Quantum Cryptography – CRYSTALS‑Kyber (KEM), CRYSTALS‑Dilithium (signatures), SPHINCS+.
Lightweight Cryptography – SPECK, SIMON, ASCON (NIST lightweight finalists).
Cryptanalysis – Side‑channel attacks, timing attacks, differential/linear cryptanalysis (conceptual).

Feedback from Cyber Security Students

“Their RSA calculation explanation was clear and step‑by‑step – finally understood modular arithmetic.”

“The AES round function breakdown helped me complete my cipher implementation assignment.”

“Great help with digital signatures and PKI. The X.509 certificate walkthrough was spot on.”

“They explained perfect forward secrecy and TLS handshake in a way that made sense.”

Worked RSA Example for Explaining the Mathematics

A small-number example is useful for showing the logic of RSA. Real systems use very large primes and approved libraries; these classroom values are only for understanding the arithmetic.

1. Build the key parameters

Choose p = 11 and q = 13. Then n = pq = 143 and φ(n) = (p − 1)(q − 1) = 120.

2. Choose public and private exponents

Let e = 7, which is coprime with 120. A matching private exponent is d = 103 because 7 × 103 ≡ 1 (mod 120).

3. Encrypt and verify

For message m = 9, c = 9⁷ mod 143 = 48. Decrypting gives 48¹⁰³ mod 143 = 9, recovering the original value.

What the explanation should say

The purpose of the calculation is not just to show modular arithmetic. Explain that the public key contains (n, e), the private key contains d, and the security of practical RSA depends on parameter sizes, correct padding, secure key generation, and careful implementation. A university report should clearly separate this teaching example from real deployment guidance.
