1. Boxing, unpacking or aliases many of the introduction of C #. NET learning experience books on the introduction of the int-> Int32 is a boxing process, the reverse is the process of unpacking. This is true of many other variable types, such as short <-> int16,long <->int64. For the average programmer, it is not necessary to understand this process, because these boxes and unboxing actions can be automatically completed, do not need to write code to intervene. But we need to remember that ...

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 ...

However, by banning digital communication, I cut off contact with all the Chinese I know. 　　Why do Chinese URLs prefer digital domain names? In the United States, really ...

ASCII Armor ASCII encoding, encoding binary files with 7bits of display ASCII code, which can be passed in only 7bits-supported emails. The MIME BASE-64 encoding is used in PGP. ciphertext ciphertext; Encrypted later information, generally unrecognized. Cryptanalysis analysis of cryptography, from the point of view of cryptography to find a loophole and attack it, PGP in cryptography is still quite solid. Even Hack ...

An American girl who lived in Beijing said she would never listen to emails with digital addresses, such as 62718298454@163.com. 　　When I heard her say that, I thought she had a point. It even left me speechless-why do we have to make an e-mail address like a number that's so hard to remember? But after I banned digital communication, I cut off contact with all the Chinese I know.

With the development of network and computer technology, the security of data storage and data exchange has become more and more important, and encryption technology has been used in data saving and data exchange very early. In order to ensure the correctness of the identities of both sides of the network data exchange, the visa system has matured. GnuPG is a set of tools for encrypting data and making certificates, and it works like PGP. But PGP uses a number of proprietary algorithms, which are among the notorious U.S. export restrictions. GnuPG is the GPL software, and does not use any patented encryption algorithm, so that ...

GPG, the GNU Privacy Guard, is a non-commercial version of cryptographic tool PGP (pretty), which is used to encrypt and authenticate emails, files, and other data to ensure the reliability and authenticity of communication data. This article will introduce the GPG technology and related tools, designed to help online surfers "sincere" communication. First, PGP overview before introducing GPG, let's take a look at the basic principles and application rules of PGP. Like many encryption methods, PGP uses double keys to ...
