Binary Code Hexadecimal

Base64 is one of the most commonly used encodings, such as the development of passing parameters, the <img/> tags in modern browsers to render pictures directly through Base64 strings, and for messages and so on.　　The BASE64 encoding is defined in RFC2045, which is defined as: Base64 content transfer encoding is designed to describe the 8-bit byte of any sequence as a form that is not easily recognized directly by the person. We know that any data is stored in binary form on the computer. One byte is 8 bits, one character is stored in the computer ...

Blockchain is a new technology that is gradually emerging with the increasing popularity of digital cryptocurrencies such as Bitcoin.

We know that PGP (pretty) is the most popular kind of encryption software at present, it is a mail encryption software based on RSA public key encryption system. We can use it to keep the message confidential to prevent unauthorized reading, and it can also digitally sign the user's message so that the recipient can be sure of the sender's identity. It allows users to communicate securely with people they have never seen before, without requiring any secrecy to pass the key, because it uses an asymmetric "public key" and "private key" encryption system. But PGP is not a completely asymmetric addition ...

This article mainly introduces some principles and background knowledge about PGP implementation. Other documents on the installation and use of PGP refer to other documentation provided with this article. PGP pretty-Privacy is a mail encryption software based on RSA public key encryption system. You can use it to keep your emails secret to prevent unauthorized reading, and it can also digitally sign your emails so that the recipient can be sure you sent them. It allows you to safely communicate with people you've never seen before, and you don't need any confidential channels to pass the secret.
