Recently I saw a question about “binary encryption”. They were asking people to decode a set of numbers or something, which were all 1’s and 0’s. And somebody came up with some results using a website I think.
I don’t get this. What is binary encryption? Is it just a code you can use? How do you “break” the code, if possible? Any more details would be appreciated.

The phrase “binary encryption” doesn’t mean anything in particular. The question was probably referring to ASCII, a code (not encryption) used by almost all modern computers to store text as binary numbers. There are a number of websites that can translate ASCII characters to and from binary digits.

Binary encryption involves using a special bit string as a pattern to perform some sort of logical or mathematical transformation of a source string into an encrypted string. The special bit string is called a “key.” The key can be a two-way key, in which case you are looking at something called reversible encryption. It also means that you used one of the operators that supports Hermetian mathematical operations. A key can be a one-way key, in which case you might be generating a hash - also known in math as a characteristic - which forms a sort of digital signature. Finally, if you have the public-key encryption, you have TWO keys - one public, the other private. If you encrypt a message with your private key and someone else decrypts that message with the public key, that person knows you sent it.
