IOS 7:base64 Encode and Decode NSData and NSString Objectsfri, JAN CORE servicestweetWith the release of IOS 7, Apple added support for encoding and decoding data using BASE64. In this post we'll walk through the examples using Base64 to encode and

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,

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.

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. 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
