In order to ensure that the output encoding is readable characters, Base64 has developed an encoding table for uniform conversion. The size of the encoding table is 2^6=64, which is where the name Base64 comes from. Otherwise, if you have a Base64 string, paste it into the Base64 field and press Decode. The Base64 term originates from a specific MIME-content transfer encoding. (The extra 65th character, '', is used to signify a special processing function. Base64 is a generic term for a number of similar encoding schemes that encode binary data by treating it numerically and translating it into a base-64 representation. A 65-character subset of US-ASCII is used, enabling 6 bits to be represented per printable character. If you need to encode a text to Base64, fill in the Text field and press Encode text to Base64 the result will appear in the Base64 field. The base64 encoding is adapted from RFC 1113, with one change: base64 eliminates the '' mechanism for embedded clear text. Restore the characters after Base64 encryption.īase64 encoding requires that 3 8-bit bytes (3*8=24) be converted into 4 6-bit bytes (4*6=24), and then two 0s are added in front of the 6 bits to form an 8-bit word section form. If the remaining characters are less than 3 bytes, it is padded with 0 and the output character is '=', so 1 or 2 '=' may appear at the end of the encoded output text. The Base64 online converter supports both functions of the algorithm on same page. The characters are indexed into a 64 printable character set table. I used these sites to understand how Base64 encoding really works and translated it to AL code.This tool can encrypt all characters that can be represented by utf-8 by Base64 encoding, and can also The Base64 encoding converts 8-bit characters into a universal character set. ![]() A great resource can be found here and here. I’m not going into the details of Base64 encoding itself. In that way there is no dependency on any table. For binary data the code works with InStream and OutStream variables. The Codeunit is now supporting both text and binary data. That was another challenge that I just wanted to pick up. Because they were talking about a file I figured the code should not only support strings, but also binary data. And apparently, people were still interested in having the code. However, a new question came up about Base64. So I decided to not publish the code and wait for the next update. In the early days of the Internet by Anagha Kumbhojkar The Startup Medium 500 Apologies, but something went wrong on our end. At that moment, I already read in a GitHub issue that Microsoft promised to make the Base64 functions on TempBLOB table available in the next update. Well, it turned out that it was possible and I ended up with a Codeunit that was able to convert a string to Base64 and also back into a string. ![]() Just as an excercise and at that moment I didn’t know if I would even succeed. So I decided to write Base64 encoding / decoding routines myself. ![]() Net, I figured it was going to take a while before we get Base64 support in AL code. And because those functions on the TempBLOB table are using. Unfortunately, at that time, it was not possible to call the Base64 methods on the TempBLOB table. He is building up a great library of very useful video’s, so make sure to check out his YouTube channel!Ī couple of weeks ago, I was trying to write web service examples in AL code for VS Code. Update June 13th, 2020: In this video, Erik Hougaard discusses this code and improves the performance dramatically by making use of the TextBuilder variable.
