Encoding vs Encryption: A Critical Distinction for Developers If you have ever seen a developer store a password as Base64, or heard someone say "we encode our API keys for security," you have witnessed one of the most common and dangerous confusions in software development. Encoding and encryption are not interchangeable terms — they serve fundamentally different purposes, and mixing them up leads to real security vulnerabilities. This article explains the difference precisely, shows you where each belongs, and walks through the mistakes developers make when they conflate the two. --- The Core Distinction Encoding transforms data from one format to another using a publicly known scheme.
