The only drawback is that the size of the result will increase to 33. Yeah, that’s right, 64 characters is enough to encode any data of any length. This notice may not be removed or altered from any source distribution. Base64 is an encoding mechanism which was originally made for encoding binary. The Base64 Alphabet contains 64 basic ASCII characters which are used to encode data.

None of answers satisfied my needs, I needed simple two-function solution for encoding and decoding, but I was too lazy to write my own code, so I found this: Learning Aid - Top Base64 Encodings Table GitHub Instantly share code, notes, and snippets. I needed C++ implementation working on std::string. Printf("Base-64 decoded string is: %s\n", base64_decoded) //Prints base64 decoded string.įree(base64_encoded) //Frees up the memory holding our base64 encoded data.įree(base64_decoded) //Frees up the memory holding our base64 decoded data. Printf("Base-64 encoded string is: %s\n", base64_encoded) //Prints base64 encoded string. Printf("Original character string is: %s\n", data_to_encode) //Prints our initial string. Basically, Base64 is a collection of related encoding designs which represent the binary information in ASCII format by converting it into a base64 representation. Int bytes_to_decode = strlen(base64_encoded) //Number of bytes in string to base64 decode.Ĭhar *base64_decoded = base64decode(base64_encoded, bytes_to_decode) //Base-64 decoding.

Return base64_decoded //Returns base-64 decoded data with trailing null terminator. This ensures that the data remains intact without modification during transport.Static char encoding_table = //Once we're done reading decoded data, BIO_read returns -1 even though there's no error.īIO_free_all(b64_bio) //Destroys all BIOs in chain, starting with b64 (i.e. Base64 Encoding Table Solving the Endgame Base64 encoding is a process of converting binary data to an ASCII string format by converting that binary data into a 6-bit character representation. When the term "Base64" is used on its own to refer to a specific algorithm, it typically refers to the version of Base64 outlined in RFC 4648, section 4, which uses the following alphabet to represent the radix-64 digits, alongside = as a padding character: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/Ī common variant is "Base64 URL safe", which omits the padding and replaces +/ with -_ to avoid characters that might cause problems in URL path segments or query parameters.īase64 encoding schemes are commonly used to encode binary data for storage or transfer over media that can only deal with ASCII text (or some superset of ASCII that still falls short of accepting arbitrary binary data). The term Base64 originates from a specific MIME content transfer encoding.
