If others find this interesting, maybe they can find ways to make it reliable the first time.
TO FACTOR WITH THIS METHOD:
1. Start by finding the next higher square from the target number (the one to be factored),
2. Subtract target number from square (or from the product, if after the first iteration),
3. Find the square root of the difference, round up, and add/subtract from the square (e.g., 324-319 or 18 squared minus 319, sqrt 5 is 2.23, so use three; 18 squared becomes 15x21),
4. Subtract new product from target number, if the difference is less than ei ..read more

Risk management is paramount. I always set stop-loss orders and limit the amount of capital I risk on a single trade to protect my account. Emotional discipline is equally important; it's easy to get carried away by fear or greed. Sticking to a well-defined trading plan and avoiding impulsive decisions has been instrumental in my trading journey. I also advocate continuous learning. The forex fbs broker market is dynamic, and there's always something new to grasp. Engaging with trading communities, reading market analysis, and attending webinars or courses have helped me refine my skills and a ..read more

Underneath rest 5 by 3,
Crack them, space them, set them free.
The code (I'll share) is CHEMISTRY.

This forum has been mostly moribund for many years. There's not much traffic.
Unfortunately, I don't know of any others focusing on classical cryptography.

That said, this was, when people actually read it, a good forum for properly presented cryptographic challenges.
But "properly presented" meant including all details of how the encryption was done, except the key.

Nonfungible tokens (NFTs) are unique digital assets based on blockchain technology, usually built on Ethereum or other compatible blockchains.

A software told me it's a kind of Checkerboard encryption. Correct?
Whatever substitution it is, it's not a secure encryption. Every used letter should appear with same frequency but it does not and that already makes the encryption weak.

Here is my attempt to create an encryption algorithm. I wrote little text, encrypted it, and here is the result.
I suppose it'll be easy for you to break this encryption. Is there something you need for that? Something…realistic, that is. Because…imagine situation. You try to decrypt the communications of some bad guys…and they'll not give you key, plain text, or the algorithm… So…that's the situation.
You only know that this is something what one of them put together, or at least that's what other analyst saying. And searching the web, you saw this in action only with text. Never anything els ..read more

dabombguyman: Do you know about any other crypto (not currencies. For gods sake, not that) forum? I know I can google them, I did, but I'm interested more in some recommendations.
