What this tool does not do / Limits
This encodes text to RFC 4648 Base32 only. It is not encryption and it does not protect secrets; anyone can decode the output.
Frequently asked questions
Why is the output all capital letters and digits?
Base32 uses the 32 symbols A-Z and 2-7 by design, which keeps it readable and safe for systems that reject mixed case.
What are the = signs for?
Padding that fills the final group to a multiple of eight symbols when the input length needs it.
