Frequently asked questions

Does the Base58 Encoder and Decoder cost anything?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the utility.
Can you see what I put into this utility?
No. The Base58 Encoder and Decoder runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
What problem does the Base58 Encoder and Decoder solve?
In practice it gets used for three things: inspecting an identifier encoded in Base58. Generating short IDs without ambiguous characters. Understanding cryptocurrency address formats. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Will this work on a tablet?
Yes. The page is responsive and the utility works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
