# Creating Random Pad from XORed Sections of Pi

If two strings of equal length from random offsets in Pi were XORed together, would this result in a cryptographically secure random number suitable for use in a one-time pad? If so, would this mean that using a secure low-bandwidth channel, you could bass three digits (two offsets and a length) to provide an arbitrarily long pad?

• OTP is information-theoretically secure even for unbounded adversaries. $\pi$ is not a good random number generator. Therefore no! – kelalaka Dec 24 '19 at 17:32
• If a single Pi based stream cipher (not an OTP) is not secure and biased, then XOR'ing two of them together won't make much of a difference. Have you read this Q/A. If so, does it answer your question. If not, what questions are still left for you? – Maarten Bodewes Dec 28 '19 at 20:48
• Thank you for the pointer. This, and the comments here, have answered my questions. – user4372 Dec 29 '19 at 21:10
