base64 character set

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

Atitit. Base64 encoding principle and implementation design, atitit. base64 encoding Atitit.Base64 encoding principle and implementation design     1. Base64 encoding 1 1.1. Why use your own base64 encoding scheme 1 2. Base64 encoding origin 1 3.

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 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.

I. Brief description MD5: All called message digest algorithm 5 (Information digest algorithm), can be encrypted, but not decrypted, belong to one-way encryption, usually used for file verification BASE64: The 8-bit byte of any sequence is
