- Oct 13, 2025 Hybrid Encryption and the Cost of Encrypting Long Messages Why a public-key operation wraps a symmetric key instead of the message, how RSA-KEM and ECIES derive that key, and what the encapsulation interface changes. cryptography
- Nov 1, 2024 RSA Padding and Why Textbook RSA Fails Textbook RSA is multiplicative and deterministic, which makes it malleable and open to chosen-ciphertext attacks; how OAEP and PSS impose the structure that closes them. cryptography
- Jan 9, 2022 RSA Key Generation and the Prime Search Generating two large primes, testing them for primality, deriving the private exponent, and why the resulting key has structure that must be checked rather than assumed. cryptography
