I. Base64 encoding Principle
Step 1: Convert all characters into ASCII codes;Step 2: Convert the ASCII code into an 8-bit binary code;Step 3: Combine the binary three into a group (less than three are supplemented with 0) with a total of 24 bits

This test today provides the base64 encoding rules. You need to write a program to implement base64 decoding. (For strings that contain Chinese or other multi-byte characters, pay attention to their encoding. For example, for Chinese characters, use
BASE64 encoding algorithm of Android Data encryption preface:In front of the study summed up the usual development encountered in various data encryption methods, the end will be encrypted binary data Base64 encoding, play a two times the effect of
Objective:In front of the study summed up the usual development encountered in various data encryption methods, the end will be encrypted binary data Base64 encoding, play a two times the effect of encryption, in fact, Base64 from the strict sense
One:. Base64 Supplement"' OBJC1.base64 Simple ExplanationDescription: Base64 can be a cornerstone of cryptography and is very important.Features: Arbitrary binary data can be BASE64 encodedResult: All data can be encoded as a text file that can be
I bet when you see the word base64, you will think where you have seen it, because you can see this article online.
Article You have already used it in the background. If you know something about the binary number, you can start to read it.
1. The origin of Base64Base64 was first used to troubleshoot e-mail transmission issues. Because of "historical issues," earlier e-mail gateways allow only ASCII (binary 00000000-01111111) characters to be transmitted, and if non-ASCII characters
What is base64?
According to rfc2045, base64 is defined as base64 content Transfer Encoding. It is designed to describe the 8-bit bytes of any sequence as a form that is not easily recognized by people. (The base64 content-transfer-encoding is
The previous study summed up the usual development of the various data encryption methods, the final will be encrypted binary data for BASE64 encoding, played a two times encryption effect, in fact, Base64 from the strict sense is not a
Many friends may use the base64 encoding format, but the encoding is not equivalent to encryption (encoding is not encrypting). Encoding only formats the data, and encryption makes the data confidential.When you select the encoding method, base64
The timcodecb64 class is a base64 encoding and decoding class provided by the Symbian platform. You may not find the description about the base64 encoding and decoding class in the SDK of the official documentation. However, this class does exist in
Base64 encoding. First, we should clarify why there is a 64 character in it? In fact, because the encoding uses 64 plain text to encode arbitrary binary files, it only uses the A-Z, A-Z, 0-9, +,/This 64 characters, some people who have "a little
I. Encoding Rules:
Base64 encoding requires that three 8-bit bytes (3*8 = 24) be converted into four 6-bit bytes (4*6 = 24 ), then add two zeros before the six bits to form the 8-bit one-byte format.For example, the string "3 ":11010101 11000101 00
BASE64 encoding can be used to pass longer identity information in an HTTP environment. In other applications, it is often necessary to encode binary data as appropriate in the form of URLs (including hidden form fields). At this time, the adoption
Python uses the base64 module to process base64 encoding.
The base64 module is used for base64 encoding and decoding. This encoding method is very common in email.It can encode binary data that cannot be displayed as text information to be displayed.
