Read all bytes from any file

Solved!
Go to solution

Hey! I would like to read any type of file and read them as binary (Obtain an 1d array of U8 or an 2d array 8bits x sizearray) and when I have manipulated it, rebuild the original file.

Hi Pepe,

 

I would like to read any type of file and read them as binary (Obtain an 1d array of U8 or an 2d array 8bits x sizearray)

Use ReadBinaryFile function…

 

when I have manipulated it, rebuild the original file.

Why do you want to manipulate anything, when you need the original file afterwards???

Best regards,
GerdW

Well such a vague question demands an equally vague answer.

I wanna encrypt any file, for example a vi or a video or a simple .txt, so, when this file encrypted is decrypted...

 

The function "read binary file" is able to read any type of file?

since every file is just a bunch of zeros and ones ... yes

RTSLVU had an example for the encoding,

to reverse that, you just have to do the same with F^-1 for the decoding.

The "vague answer" above is actually a good starting point!  🙂

if you want to have "secure" encryption, use an external library/program that does that for you, like openssl, and not build it yourself.

you could run commandline call through the system-exec-vi.
