For example, the Xbasic script below converts a base64 encoded png into it's original binary data and saves it to disk using storage: dim img64 as c = "iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg="Ī5storage_savedata("::storage::disk",decodedImg,filename,mime,result) This function can be used to convert data into it's original file format, which can then be saved as a file to storage. The base64Decode() function returns binary data decoded from a base64 encoded character string. Can be used to convert base64 images back to their original format. If your base64 string has a data prefix containing a mime type, you must remove it before calling this function.Ĭonverts a base64 encoded string back to its binary data.
Base64 encoding schemes are commonly used when there is a need to encode binary data, especially when that data needs to be stored and transferred over media that are designed to deal with text. libb64, OpenSSL Base64, Apple’s Implementations, arduino-base64 etc. There are number of C libraries available for encoding and decoding as well i.e.
test.cpp can be used to test the functionality. base64.cpp contains two simple C++ functions to encode and decode string from/to Base64: base64encode and base64decode. A shell script that uses the GNU C++ compiler to compile test.cpp and run it. This is a very simple implementation of base64 encoding and decoding in C programming language. This file is apparently used for or as a source file manager. DecodedData as B = base64Decode(C encode_string)Ī character string containing base64 encoded data. Base64 encode your data without hassles or decode it into a human-readable format. Base64 data is generally url-safe, and that’s why they can be used to encode data in Data URLs.
