DV vs. OV vs. EV Certificates: A Technical and Trust Model Comparison
How Domain, Organization, and Extended Validation differ at the PKI and issuance-process level, why browsers stopped showing the EV green bar, and what changes (and doesn't) under PQC signatures.
Read More about DV vs. OV vs. EV Certificates: A Technical and Trust Model Comparison→Classic vs. Computational Cryptography: A Brief History
How cryptography moved from physical substitution/permutation devices to Shannon's information theory and, later, computational hardness assumptions.
Read More about Classic vs. Computational Cryptography: A Brief History→The Rise and Fall of SSL: From 1.0 to 3.0
SSL's origins at Netscape, the design flaws that killed 1.0 and 2.0, and how POODLE's padding oracle attack ended SSL 3.0.
Read More about The Rise and Fall of SSL: From 1.0 to 3.0→Symmetric vs. Asymmetric Encryption: The Key Exchange Problem
Why AES is fast but requires a pre-shared key, how RSA and Diffie-Hellman solve key distribution mathematically, and why TLS needs both.
Read More about Symmetric vs. Asymmetric Encryption: The Key Exchange Problem→The TLS Transition: Versions 1.0, 1.1, and 1.2
How SSL became TLS, the BEAST and CRIME attacks that forced protocol changes, and why TLS 1.2 remains in use only under strict cipher suite configuration.
Read More about The TLS Transition: Versions 1.0, 1.1, and 1.2→Why TLS 1.3 is the Gold Standard (For Now)
TLS 1.3's architectural simplification, the legacy algorithms it removes outright, how 0-RTT resumption works, and Perfect Forward Secrecy via ephemeral Diffie-Hellman.
