Credential Encoding Guide: Safe Patterns for Secrets in APIs Every API call that requires authentication encodes credentials in some form. The question is whether that encoding is being used correctly — as a transport formatting mechanism backed by real security controls — or whether it is being relied upon as a security layer it was never designed to be. This guide covers the correct patterns for credential transmission in APIs, explains what the encoding is actually doing in each case, and shows you the anti-patterns that create real vulnerabilities. --- HTTP Basic Authentication HTTP Basic Auth is the oldest and most widely used credential scheme. The format is defined in RFC 7617. How It Works The client concatenates the username and password with a colon, Base64-encodes the result,…
