One-Time Pad: True or False Suppose a message $M$ was encrypted with a one-time pad. If we learned the first half of the original text is some substring $s$, would we have a better chance of cracking the rest of the message?

Is this true or false? I know that OTP is unbreakable in theory but with the knowledge of the first portion of the string, would this help us?
In theory no, there will be no better chance.

The key must be at least as long as the original text. The key must have high entropy (simply said, it should be random enough). Then revealing any part of the original text has no effect on the decryption.

In practice, if the process is realized improperly, there can be some issues:


If the key is shorter that the original message.
If the key is not random enough.
If the the OTP generator is not random enough and the attacker knows a lot of other OTPs produced by this generator.
