Encryption vs Hashing: What's the Difference?
Encryption scrambles data so it can be unscrambled later with a key. Hashing turns data into a fixed fingerprint that can never be reversed. One protects secrets; the other verifies them.
Cryptographic salt vs pepper
What is a cryptographic salt, and how does it differ from pepper in password hashing? A technical breakdown of salted hashes, bcrypt salt rounds, and best practices.
Password Salt and Hash: How to Store Passwords Safely
Storing a password means hashing it with a slow algorithm and a unique salt, never encrypting it or saving it in plaintext. Here's how salting and hashing actually protect users.
What Is Password Salting? Why Two Identical Passwords Should Never Match
Password salting adds a unique random value to each password before hashing, so identical passwords produce different hashes and precomputed attacks fall apart.
Password Storage Best Practices Every Developer Should Follow
Storing passwords safely comes down to one rule: never store the password. Here are the password storage best practices that actually hold up against modern attacks.
Password Validation: How to Verify Credentials Securely
Password validation is more than a regex for length and symbols. Here is how to check credentials the way modern guidance actually recommends.
JavaScript SHA256: How to Hash Correctly and Securely
How to compute SHA256 in JavaScript with the Web Crypto API, plus what SHA256 is safe for, what it is not, and the mistakes that turn hashing into a vulnerability.
What Is Hashing? A Plain-English Guide to One-Way Functions
Hashing turns any input into a fixed-size fingerprint that cannot be reversed. It quietly powers password storage, integrity checks, and digital signatures across modern software.
Plex Data Breach: 20 Million Users Forced to Reset Passwords
A breach of Plex's systems exposed usernames, emails, and hashed passwords for approximately 20 million users, forcing the streaming platform to trigger a mass password reset.
