base64 - What is base 64 encoding used for? - Stack Overflow The base64 is a binary to a text encoding scheme that represents binary data in an ASCII string format base64 is designed to carry data stored in binary format across the channels It takes any form of data and transforms it into a long string of plain text
What is the real purpose of Base64 encoding? - Stack Overflow Base64 encoding occurs in size of 4 characters Because an ASCII character can take any out of 256 characters, which needs 4 characters of Base64 to cover If the given ASCII value is represented in lesser character then rest of characters are padded with = = is not part of base64 character set It is used for just padding
algorithm - Why do we use Base64? - Stack Overflow Wikipedia says Base64 encoding schemes are commonly used when there is a need to encode binary data that needs be stored and transferred over media that are designed to deal with textual data Th
Why does a base64 encoded string have an = sign at the end The part about "One case in which padding characters are required is concatenating multiple Base64 encoded files " is wrong For example when concatenating two base64 files where the source bytes for each file is 3 bytes long the base64 strings will be 4 characters long and have no padding bytes
Base64 decode snippet in C++ - Stack Overflow void base64_encode(string out, const vector<uint8_t> buf); void base64_encode(string out, const uint8_t* buf, size_t bufLen); void base64_encode(string out, string const buf); void base64_decode(vector<uint8_t> out, string const encoded_string); Use this if you know the output should be a valid string void base64_decode(string
How to check whether a string is Base64 encoded or not All that you can determine is that the string contains only characters that are valid for a base64 encoded string It may not be possible to determine that the string is the base64 encoded version of some data for example test1234 is a valid base64 encoded string, and
How to display Base64 images in HTML - Stack Overflow If you use base64 encoding, you're adding 33% overhead to the size of the image, additional CPU and memory requirements both when encoding and decoding, cluttering up the DOM with extra data that doesn't need to be there, and imposing stringent and inconsistent limits on sizes and resource types
Base64: What is the worst possible increase in space usage? Base64 encodes each set of three bytes into four bytes In addition the output is padded to always be a multiple of four This means that the size of the base-64 representation of a string of size n is: ceil(n 3) * 4 So, for a 16kB array, the base-64 representation will be ceil(16*1024 3)*4 = 21848 bytes long ~= 21 8kB
