Cryptocurrency base

Cryptography (not cryptology, which contains cryptography and cryptanalysis) is a study of encryption from a mathematical point of view. It is also used for secret communication, allowing the world to see an encrypted message in case someone is listening, and not allowing them to know the real word. Only the intended recipient can read it. As you mentioned, you can also “register” things using a similar scheme, but where “pre-decrypt” (my term) is something, and other people linking your cryptographic key can show that you have signed something.

So, cryptography is used almost exclusively in security areas. You can only restrict those authorized to access secret data. This is useful for messaging, ensuring that only paid customers can install the software and be held accountable (at least trying to prevent people from “joking” with their phone.

You can also provide some security in other ways. Some “dark networks”, especially Freenet, do not censor information. Each user stores the data on their computer, so deleting it will not remove the data from the network. After downloading the report, it can be almost impossible to delete it. In the case of illegal content, you can put it on a computer without knowledge. However, since it is encrypted, the judge should not be guilty of keeping the data on the computer because not only is it impossible to prove that your computer contains illegal content, but even if you can, you can. Please do not log in unless you are intentionally trying to crack it through other illicit routes.

With Bitcoin, you can also find crypto applications at:

bit message

Tahoe-LAFS (and other encrypted file storage systems)

PGP / GPG (plain text encryption so you can send emails to people without other people reading the message)

Finally, I will say that unique passwords may be a growing trend. I have a keychain that, to connect to the program, every time I need a new password. Only 64,000 random passwords will be verified as “I am”, so the attacker will not be able to access the passwords, but will not be able to steal the password that you use and reuse. Once applied, it can no longer be used.

Uses of cryptography

The crux of what you have learned so far is that cryptography is the art of storing and writing information in such a way that it is only revealed to those who need to see it. Hide from everyone else. Before the information age, cryptography was only used to guarantee the secrecy of information. Encryption has been used to ensure the confidentiality of communications from spies, military leaders, and diplomats. Egyptian hieroglyphs, scythe passwords used by Spanish Spartans, plaster, and various physical assistive devices were used throughout history down to modern times. These devices underwent other changes when computers and electronic devices appeared, which contributed significantly to cryptanalysis.
