Rosenmüller's Fossa

Let's look at the **Crypt Hole** theory.

**Cryptographic algorithms and protocols** An encryption algorithm in our reality is a rather complex computer program that generates a closed text or an encrypted message from plaintext. The process of converting plaintext into encrypted form is called encryption, and the reverse process is called decryption (decryption). What is a hash function? In short, it is a one-way trivial algorithm that allows you to obtain a bit string or a number of a fixed length from a message passed to it. As a result, this number will be unique, it will represent and depend on all the characters in the source text. Once the hash is calculated, you can try to manipulate it, for example, try to restore the original text, but this process will always fail. However, this only applies to cases where all the original symbols are known. If some of the letters or symbols are unknown, then it will be impossible to obtain the source text from the hash. Thus, the point of the cipher method is to make the original message unintelligible to outsiders by making the letters or symbols look similar due to the substitution or substitution method. The algorithm hides information about what the source text was. The hidden source text itself is called hidden text. All encrypted or hidden texts are used for
