How Bcrypt Hashes Passwords (And Why Cost Factor Matters)
Bcrypt is the password-hashing standard most modern apps still rely on. Here's how the Blowfish-based KDF works, why the cost factor matters, and how to pick a value that ages well as hardware speeds up.
What Is a Checksum and Why It Matters for Data Integrity
A checksum is a small number computed from a block of data that lets you verify the data has not changed. Here is why this simple idea underpins file downloads, network protocols, and storage systems.
Hashing Algorithms Explained: MD5, SHA-256, bcrypt — When to Use Which
MD5 and bcrypt are both called hashing algorithms, but they serve completely different purposes. This guide explains what makes a hash function suitable for checksums versus password storage.
Encoding vs Encryption vs Hashing: The Key Differences Explained
Treating Base64 as encryption or MD5 as a secure hash are among the most common security mistakes developers make. This post draws a clear line between encoding, encryption, and hashing.
