In this document, the master (permission) password and user password are translated, I think the permission password is better, so it is called t

SSH encryption principle, RSA Asymmetric Encryption algorithm learning and understanding

First of all, it is said that SSH is not the three main framework of Java tradition, but a kind of security shell protocol based on application layer and transport layer, and familiar with Linux friends often use a tool of SSH Secure Shell cilent. This paper is also based on this tool encryption principle of learning, in the SSH encryption principle, the use of R

Implementation of asymmetric encryption and digital signature RSA Algorithms (public key encryption-> Private Key decryption, private key encryption-> Public Key decryption)

The RSA algorithm is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and is also popular. Its security is based on the difficulty of big integer factorization, while the big integer factorization is a famous mathematical problem. So far, there is no effective solution, therefore, the security

Encryption in another way-Liu taotao, a famous programmer, talks about the technology of distorted encryption Transformation

this method for one software. I think it is a good method. What are the advantages? That is, my encrypted code is seamlessly connected to the project. Another is the analysis of the OBJ format, which is much simpler than the C ++ source code. There is a symbol in my OBJ file. This OBJ will tell me that there is a symbol here. So I think the disassembly obj is safer than the disassembly exe. The specific method is to parse the OBJ file, keep the data part unchanged, decompile the code part, conv

When it comes to encryption, a digital signature is associated with two concepts that are often confused. Encryption: Encryption is a way to send information in a password way. Only the person with the correct key can unlock the password for this information. For other people, this information looks like a series of random letters, numbers, and symbols.
