I'm trying to do the validation files (converted to MD5 hash) using the sendwithmetadata command.
I believe that I did not understand the correct functioning of this command and parameter data-hex.
I thought that if I send the same data-hex twice, the second time, he would return saying that this data-hex has been validated.
But it does not. The command is accepted usually with the same hex-date and because of that I did not understand what use to pass the data-hex.
There is another command to do this validation? Or what is the proper way to use the sendwithmetadata and not allow data-hex same?
