This post explores the nuances and common pitfalls to avoid. It takes any form of data and transforms it This code is called base64 and simply put it is meant to convert binary files to text format. To achieve this, the encoder may add one or two equal (=) signs at the end of the encoded string Now let's see how we can decode a Base64 string to its raw representation. Base64 is a binary-to-text encoding scheme. Example: the 8char string Portland is valid Base64. +/”) as char_set and For example, MIME's Base64 implementation uses A-Z, a-z, and 0-9 for the first 62 values, as well as "+" and "/" for the last two. Base64 encoded images can be embedded using img tags or CSS, When dealing with large streams, like a file sized over 4GB - you don't want to load the file into memory (as a Byte[]) because not only is it very slow, but also may cause a crash Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The Encoding: To encode a string to Base64 format, you can first convert the string to Xstring using the function module SCMS_STRING_TO_XSTRING, and then use the function For example, I've found that the cordova Camera plugin returns base64 with unnecessary whitespace.
