String Obfuscator

Made for the task at hand.

Prepare readable examples of emails, account identifiers, and other sensitive strings without exposing their middle portion. Choose the mask character and visible prefix/suffix lengths; Unicode code points are counted so the output retains the original character count.

How to use

1. Enter the text and select a mask character.
2. Set how many leading and trailing characters stay visible.
3. Copy the masked value and check its reported length.
