Base64 Module Preface Yesterday the team's sister came to ask questions about the POP3 protocol, so today a little bit about the format of the POP3 protocol and the poplib in Python. And the POP server back to the data in a part of the need to use

Python uses the base64 module for binary data encoding. Preface Yesterday, my team asked me about the POP3 protocol. So today I have studied the POP3 protocol format and the poplib in Python. Some of the data transmitted back by the POP server needs

Brief introductionFeatures: RFC 3548:base16, BASE32, Base64 data encoding. Converts the binary data to an ASCII sequence that is suitable for plaintext protocol transmission. Transformation8bits contains valid data for 6, 5, or 4bits for each byte,

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

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

Base64 encoding and decoding for node. js learning, and node. jsbase64 Encoding I. Base64 encoding Origin Why is Base64 encoded? Because some network transmission channels do not support all bytes, for example, traditional mail only supports

Base64 Is based on 64 Printable characters to represent the representation of binary data. Because 26 = 64 , So every 6 It is a unit that corresponds to a printable character. Three bytes in total 24 Bit, corresponding 4 Items Base64 Unit, that is 3

Data/base64 webmasters often use more data. I often see that they generate data/base64 data for images and then input the data. This shows a very long string, now let's take a look at the php input method. Let's take a look at data/B. Data/base64

I. ORIGIN of BASE64 coding Why would there be Base64 code? Because some network transport channels do not support all bytes, for example, traditional messages only support the transfer of visible characters, such as ASCII code control characters
