what base64 encoding

BASE64 encoding is a common character encoding, which is used in many places. JDK provides very convenient BASE64Encoder and BASE64Decoder, which can be used to conveniently complete BASE64-based encoding and decoding. The following are two small

The plus sign (+) is part of base64 encoding, And the plus sign is treated as a space in querystring. Therefore, when a string containing base64 encoding is directly used as a part of the URL, if it contains a plus sign, then when querystring is

Base64 is one of the most common encoding methods used to transmit 8-bit code on the network, base64 requires that each three 8-bit bytes be converted into four 6-bit bytes (3*8 = 4*6 = 24), and then 6-bit bytes be added with two more high 0 values,

Supports Chinese base64 encoding/Decoding (Original) I wrote a simulation server yesterday to test my terminal and used base64 encoding/decoding. I used the goahead code. I found that it does not support Chinese characters. I modified it myself and

The first time after working with the Java encryption mechanism, the requirement is to use RSA digital signature. At that time, after seeing a face of a confused force, looked up all kinds of information.For the learning process I took a lot of

The BASE64 encoding requires the conversion of 3 8-bit bytes (3*8=24) into 4 6-bit bytes (4*6=24), followed by 6 two in front of 0 bits, forming a 8-bit byte form. If the remaining characters are less than 3 bytes, then 0 is populated with the

Base64 is one of the most common coding methods for transmitting 8Bit byte code on the network, and you can view the rfc2045~rfc2049, which has a MIME detail specification. Here we share a way to convert a picture to the Base64 encoding format:

Analysis of Base64 encoding principles and PHP implementation Base64Is a representation of binary data based on 64 printable characters. Because the power of 6 in 2 is equal to 64, every 6 characters is a unit, corresponding to a printable character.

This article describes PHP-safe URL string base64 encoding and decoding, and replaces insecure characters with base64, if you want to use base64_encode and base64_decode, the generated string may not be applicable to URL addresses. The following

Base64 This is a binary encoding method that is converted to printable characters. Mainly used for mail transmission.Base64 will be 64 characters (a-z,a-z,0-9,+,/) due to the basic character set. Converts all symbols into a character set.Coding:The
