Combine one-time pad material or flip masked bytes—hex pairs must align.

About XOR hex strings

XOR two equal-length hex strings byte-wise—local crypto helper. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.

How to use this page

Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.
