- 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
- 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
- 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
- How do I encode and decode a base64 string? - Stack Overflow
Remember base64 is primarily intended for representing binary data in ASCII, for storing in a char field in a database or sending via email (where new lines could be injected) Do you really want to take character data, convert it to bytes, then convert it back to character data, this time unreadable and with no hint of what the original
- How can you encode decode a string to Base64 in JavaScript?
I have a PHP script that can encode a PNG image to a Base64 string I'd like to do the same thing using JavaScript I know how to open files, but I'm not sure how to do the encoding I'm not used to
- 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
