Frequently asked questions
- Q. Is Base64 encryption?
- No. Base64 only changes how data is written so it can travel through text-only channels. Anyone can decode it, so never use it to protect secrets.
- Q. What is URL-safe Base64?
- It replaces + and / with - and _ and drops the = padding, so the result can be used in URLs and file names (as in JWTs).
