wav file encryption using TEA

[GerdW]

Hi kulsman,

you still attach a LV2013 version of your VI. You should use "Save for previous" in the file menu...

Hello GerdW,

It seems like labview saved the file into a new folder.

Bump anyone

Hi kulsman,

read as U8 array:

[kulsman]

I have implement your suggestion, but I am getting this wierd error.

Error 116 occurred at Read from Binary File in reading_in_data.vi

Possible reason(s):

LabVIEW:  Unflatten or byte stream read operation failed due to corrupt, unexpected, or truncated data.

Please view the changed file.

Hi kulsman,

I appologize, that's my fault.

You have to provide a scalar U8 as datatype for ReadBinaryFile:

(Reading the context help really proves helpful...)

Thank you so much. I am finally able to read in the wav file.

 Hi Kulsman,

I am also working on a project trying to do encryption on a waveform data. Were you able to decrypt and recreate the wav file after encryption? If so, how?

Warm Regards,

Matt

Hello GerdW,

I am also trying to do encryption, but instead I am trying to do TEA on a waveform data. Is there a way to pass a double into TEA and encrypt it? Because if I convert the array data of the waveform (which is type double) into U32, all of the values become 0 since the waveform values are never greater than 1. Attached is a picture of what I am trying to do. Thanks for your help.

Warm Regards,

Matt
