LabVIEW Utility VIs for Base64 and Base32Hex Encoding Using LabVIEW

[Christian_L]

Overview

This example can be used to convert (encode and decode) strings between ASCII, Base64, and Base32Hex encoding.

Description

Base64 encoding is commonly used for encoding passwords and attachments (MIME) in e-mail and other online communication.

Note that Base64 and Base32Hex encoding are not encryption and do not add any security to the information. It is intended to convert any string into a format that can be reliably transferred across any network. In that example, there is a "Main VI" that contains all the operations front panel.

Requirements

Software:

• LabVIEW 2012 (or compatible) 

Steps to Implement or Execute Code

1. Run VI.
2. Select which operation you want to handle and enter the input for converting it.

Thanks man!  Saved me quite some time!

thank you very much! i have tried many other VIs, but this one is really helpful.

Hi,

I am currently writing a GUI for the Mission Control client of our little Cube Satellite built by the students of the Aachen university in germany as part of an educational space program of QB50. This Satelite will send his Housekeeping data down to earth over 70cm band and the housekeeping data is encoded as Base32Hex. Does anybody know if there are some utils for encoding/decoding Base32Hex to Hex?

One example:

The satellite will for example send down to earth this Beacon as a little seqence of strings by morse-code signals:

               "ON04DLXASJJG1A4000008O31JPG003NH0036BHQ5O00000000000032"

The first  digits "ON04DLX" is the Satellite's world-wide amateur-radio designator name and is not part of the housekeeping data to be decoded, so they can be ignored.

The Housekeeping data is incorporated in the Base32Hex encoded string:

                "ASJJG1A4000008O31JPG003NH0036BHQ5O00000000000032"

As the satellite sends it down to earth in form of morse codes the char set is restricted to capital letters and the numers fro 0 to 9: "0123456789ABCDEFGHIJKLMNOPQRSTUV"

The Beacon string decoded from base32Hex to Hex string  looks exacltly like:

               "572738054400000023030CF30000778800332E3A2E000000000000000062"

I got the decoded hex-message of the example above by use of the following web-page:

http://tomeko.net/online_tools/base32hex.php?lang=en

If i have the beacon decoded in the hexadecimal form, i am able to translate the data into human readable strings that would

contain data about the health of the satellite. In fact i was able to modify the little peace of Labview code posted in this threat above such that it exactly translates this Hexstring  in decimals like we need it:

87  39  56  5  68  0  0  0  35  3  12  243  0  0  119  136  0  51  46  58  46  0  0  0  0  0  0  0  0  98

And finaly those decimals would be the Data of our satellite which would tell us about the health of the satellite

like this:

So what i really need is a peace of code in Labview that could decode from Base32Hex strings to Hex-String.

Can anybody help me to find a Base32Hex to Hex decoder or help me how i could build one in Labview because i

don't have any idea how to write such a decoder?

I added the Base32Hex conversion VIs to the document above.

Thank you verry much, you saved me a lot of time

Glad to help out students and space research. I'm originally from Germany myself, and worked at the NI office in Aachen for a year about 15 years ago.

Hi Christian,

Yes you did,in any case! Not only for our team, but also for the amateur radio comunity. Besides of the main mission control client, i will build a small App that translates the beacon and housekeeping text (CW already decoded by FLDIGI or the like) that shows the data in a nice fashion which will be offered for download from within our website and also here.

As a little thank you, i leave a  video about some aspects of our Mission control client (it's in french unfortunately):

And an interview i gave for a TV-show at ARTE, there you will see an older version of the client of our former satellite project (WREN) in action:

Reading through the rest of your original comment, I realized that the human readable form of the data (byte array), is one of the intermediary steps in my code before getting to the ASCII and Hex output. I updated the attached Base32Hex conversion VI to also output the byte array which will save you the step of converting from Hex to Byte array.

Thanks alot ! Working superb :D.

Thanks for sharing code.

Hi Christian,

I made a couple of test and tried to speed up the function.

This should work better.

Cheers
