# ⊕: What is the meaning of the $\oplus$-symbol?

What does this mean? $$a \oplus b$$

I've seen this notation in a text about one-time-pads. Is it XOR?

• Yes, in the context of one-time pads it is certainly the bitwise exclusive-or of two bitstrings. – MJD Jun 20 '18 at 20:04
• Post this as an answer, if you want to. – user1511417 Jun 20 '18 at 20:05
• I actually only see a question mark. Consider looking through the MathJax tutorial and finding it there. – gen-z ready to perish Jun 20 '18 at 20:14
• Is $\oplus$ (LaTeX/MathJax \oplus) the symbol you want? It would work better across different devices than directly entering the symbol. (Also @ChaseRyanTaylor) – Joonas Ilmavirta Jun 20 '18 at 20:17
• Now the problem is, that this question is more difficult to google. I assume that this question raises quite often. – user1511417 Jun 22 '18 at 9:27
