Symmetric encryption methods use the same key for encryption and decryption. In historical procedures, two encryption classes can be distinguished. In the first case, as with the Caesar encryption used in the example, the letters of the plain text are replaced by other letters. With the Latin word substituere (German: "replace") they are called substitution procedures. In contrast, in the second encryption class, called transposition (cryptography), each letter is as it is, but not where it is, its place in the text is changed, the individual letters of the text ("Reverse") of a text, for example, the secret text "SINMIEHEG" is created from the plaintext "secret." This is a very simple form of transposing encryption.
Recently, I have made interesting discoveries on the Internet during a small research.
There were peculiar abbreviations like MLSG or also DRC
I've recorded everything and somehow encrypted it a bit, you can never know.
Unfortunately, I did not notice the private key ....
I've also found these numbers, just like the photo
5438652.016 5345315.347
5436553.777 5344689.902
5435250.415 5343343.955
5436241.654 5345052.365
5435985.013 5344360.201
5436005.729 5344656.558
5435526.326 5344052.996
5435036.656 5343613.509
5438148.262 5343553.400
But maybe who will find my lost can?
