Frequently Asked Questions
Is my data sent to a server when using the Encrypt / Decrypt Text?
No. The Encrypt / Decrypt Text is a fully client-side utility. All data processing, calculations, and conversions are handled locally in your browser. No input text, payloads, or keys are uploaded to any external server.
Does it support bulk text processing?
Yes. You can paste large multi-line text files directly into the input area. The conversion processes the text buffer instantly using optimized string-replacement loops.
How does it handle line breaks (CRLF vs LF)?
The parser detects standard carriage return line endings (Windows CRLF `\r\n`) and line feeds (Unix LF `\n`), preserving or standardizing them based on your settings.
What regex flavor does the tool support?
The regular expression matching is powered by the browser's JavaScript V8 engine, which supports standard ECMAScript regex syntax including lookaheads and unicode flag groups.
Does the Encrypt / Decrypt Text store history or cache my inputs?
No. The application runs entirely in browser memory. Once you refresh the tab, navigate away, or close the window, all inputted details, logs, and outputs are completely cleared.
Is the Encrypt / Decrypt Text compatible with mobile devices?
Yes. The interface is optimized to be fully responsive. You can perform calculations, conversions, and formats on all modern mobile, tablet, and desktop web browsers.
Does the Encrypt / Decrypt Text work offline?
Yes. Once loaded, all code and assets required to run the Encrypt / Decrypt Text reside in your browser cache, enabling offline use without an active network connection.
