LV RT RSA decrypt

[protocol]

Hi,

I would need a data integrity (and not just a hash) on LV RT.

RSA decrypt would do the trick. Is it available?

Thanks

Are you looking for data encryption or verification in the sense of knowing that your files have not been changed?

For the later case a checksum would be used. LabVIEW includes the MD5 algorithm as a VI in the Advanced File Function palette, which gives you a checksum for a given file. I have used this to create a utility to create a "fingerprint" of a LV RT system (CompactRIO) in order to verify at a later time that none of the critical files on the system have been changed.
