  2. Base64 encoding and decoding in client-side Javascript

    stackoverflow.com/questions/2820249

    Are there any methods in JavaScript that could be used to encode and decode a string using base64 encoding?

  3. Base64 encoding converts three 8-bit bytes (0-255) into four 6-bit bytes (0-63 aka base64). Each of the four bytes indexes an ASCII string which represents the final output as four 8-bit ASCII characters. The indexed string is typically 'A-Za-z0-9+/' with '=' used as padding. This is why encoded data is 4/3 longer. Base64 decoding is the inverse process. And as one would expect, the decoded ...

  4. Decode Base64 data in Java - Stack Overflow

    stackoverflow.com/questions/469695

    I have an image that is Base64 encoded. What is the best way to decode that in Java? Hopefully using only the libraries included with Sun Java 6.

  5. I have binary data in an unsigned char variable. I need to convert them to PEM base64 in c. I looked in openssl library but i could not find any function. Does any body have any idea?

  6. I have the following piece of Base64 encoded data, and I want to use the Python Base64 module to extract information from it. It seems that module does not work. How can I make it work?

    Is there a freely available Base64 decoding code snippet in C++?

  8. How to decode a base64 file with command line tools

    stackoverflow.com/questions/64454106

    I am trying to decode a base64 file using command line on my PC. The file contains a large block of encoded text. Any solution?

  9. Ask yourself do you really need to do this? 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 encoding was ?

  10. BASE64 encoding takes 3 Bytes of input stream and converts it to 4 * 3 Bytes. Each of these 3 Bytes are mapped to 64 different characters (a-z, A-Z, 0-9, "+", "/" - thus you get name BASE64). Ensure that value of substring_length is a whole multiple of 4 for BASE64_DECODE, resp. a whole multiple of 3 for BASE64_ENCODE. Thus your to_base64 function may return wrong result.

  11. 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.
