- base64 - What is base 64 encoding used for? - Stack Overflow
Base64 is also used when communicating with government Fiscal Signature printing devices (usually, over serial or parallel ports) to minimize the delay when transferring receipt characters for signing Base64 is used to encode binary files such as images within scripts, to avoid depending on external files
- Base64 decode snippet in C++ - Stack Overflow
Is there a freely available Base64 decoding code snippet in C++?
- What is the real purpose of Base64 encoding? - Stack Overflow
19 Base64 is a mechanism to enable representing and transferring binary data over mediums that allow only printable characters It is most popular form of the “Base Encoding”, the others known in use being Base16 and Base32 The need for Base64 arose from the need to attach binary content to emails like images, videos or arbitrary binary
- 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
- 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 when you decode it you will get some bytes
- Why does a base64 encoded string have an = sign at the end
513 I know what base64 encoding is and how to calculate base64 encoding in C#, however I have seen several times that when I convert a string into base64, there is an = at the end A few questions came up: Does a base64 string always end with =? Why does an = get appended at the end?
- How do I encode and decode a base64 string? - Stack Overflow
How do I return a base64 encoded string given a string? How do I decode a base64 encoded string into a string?
- 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 A rough approximation would be that the size of the data is increased
