<p>The current version of this package is an R implementation that relies on general implementations of the relevant hash functions provided by <a href="https://cran.r-project.org/package=digest">digest</a> and base64 encoding provided by <a href="https://cran.r-project.org/package=base64enc">base64enc</a>. Versions 1 and 2 were available in an earlier version of the UNF package authored by Micah Altman, which was built on custom C libraries, and is included in the version logs on GitHub.
