Password

[boone301]

Dear Michael,

I'm glad to read your VI(passwordcrack.vi), but I'm still have 2 question as follow:

1.Why the Lock State form Password-protected change to Locked (No Password) when it builded to exe?

2.Why so slow when it as a vi?

Thanks a lot!

Mmm, not sure what you are asking, but:

1) The method to try a password on a VI has a built-in delay to make it unusable for brute force crack.

2) That method doesn't work in the runtime environment (exe files).

Saludos,

Aitor

I believe that's a forced limitation by LabVIEW to prevent actions like this.

It looks like the delay on this is 100ms. Assuming you knew that your password was all lowercase, consited of only letters, and was no more than 5 characters in length it could take up to 14 days to "crack" the password.

If you throw in the uppercase letters and the numbers from 0-9 this jumps to nearly 3 years.

Aren't things like this against the law in China anyway?!?

Well the wait is a 'feature' of LabVIEW internally so you won't get a higher speed.
