To this day, there is no such thing as an absolutely undecipherable way of secrecy

Theoretically, a one-for-one secret system is indecipherable. However, considering the cost of key transmission of encryption algorithms, it is not practical. So there is no such thing as an undecipherable cipher (but a sequential cipher is also possible to decipher given the usefulness of the algorithm. ）

There are three basic criteria for measuring cryptography in cryptography: computationally secure, provably secure, and unconditionally secure.

The Kerckhoffs principle is a basic requirement of modern cryptographic encoding, that is, even if the encryption algorithm is known to the other party, the key cannot be analyzed.

For example, in 1949, Shannon proposed two basic operations that can destroy cryptanalysis, diffusion and confusion, diffusion and confusion, diffusion destroys the statistical relationship between plaintext and ciphertext, and obfuscation complicates the statistical relationship between ciphertext and key.

If you are interested in cryptography, you can refer to relevant books, but cryptography is particularly demanding on mathematics, especially number theory.

Because the current well-known encryption algorithms are all built on a mathematical puzzle. For example, the RS encryption algorithm is based on the large number decomposition problem, the Rabin algorithm is based on the square root problem of the digital modulus, the Elgamal algorithm is based on the discrete logarithm problem of the finite field multiplication group of P elements, the elliptic curve encryption algorithm, etc., it is worth noting that the elliptic curve encryption algorithm has a fast encryption speed and a similar security strength to RSA, which is already a very attractive research field.

Hope it works for you. Cryptography is still quite interesting. It's good to look into it.

It's just harder to learn. The foundation of mathematics is more demanding. Generally speaking, it is offered in the upper year of university.

There are also graduate students in cryptography. This field is an important discipline that shines in modern civilization!

The embodiment of the beauty of mathematics!

Contemptible people think that there is no, where there is a password, there is a way to crack it.

At most, the stored information is information, and the stored information can only be read out by decoding, and the general *** reading will not read out the information inside and then use it as a program execution, so it will not put the program that talks about the password box into ***. If you can pop up a box, it's either a read that supports encryption itself, or that *** is stored a**, which will jump to a web page and let you enter the password.
