Secure hash and message digest algorithms writen in plain LabVIEW designed primarily for web application authentication.
LabVIEW library includes: SHA-256, SCRAM-SHA-256, PBKDF2-SHA-256, HMAC-SHA-256 and Base64 encoding/decoding.
To install, download and run the VI Package (*.vip) using the VI Package Manager which is installed with LabVIEW.
VI Package | Version | LabVIEW | Source Zip |
---|---|---|---|
rcpacini_hashlib-0.1.0.4.vip | 0.1.0.4 | LV2019 | rcpacini_hashlib-0.1.0.4.zip |
This VI Package installs to the <LABVIEW>\user.lib\_rcpacini\hashlib
directory and is available on the diagram palette Functions > User Libraries > rcpacini > Hashlib
.
Once the VI Package is installed, open the example VI located at <LABVIEW>\examples\rcpacini\hashlib\hashlib_example.vit
.

The following sections are instructions on how to rebuild and test this package.
To rebuild the Source Zip, open the hashlib\hashlib.lvproj
(LabVIEW Project), navigate to the Build Specifications > Hashlib Source
properties, under Zip Information
update the Destination filename version and press Build.
The Source Zip is output to releases/rcpacini_hashlib-X.X.X.X.zip
To rebuild the VI Package, open the hashlib\hashlib.vipb
(VI Package Build) in VI Package Manager, update the version information and press Build.
The VI Package is output to releases/rcpacini_hashlib-X.X.X.X.vip
Once the VI Package is installed to Functions > User Libraries > rcpacini > Hashlib
, open the tests\test_hashlib.lvproj
and run the test_all.vi
.
If successful, the all_passed boolean should return True.
