<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">Update: I've merged the newest upstream 'crypt.h' with the changes already made in the RTEMS source tree. I've separated out the code using the <strong style="font-weight: 600; margin-top: 0;">rtems</strong> preprocessor directive and updated the RTEMS APIs to allow (future) use of the newer additions, such as Blowfish and NTHash from upstream. I've the entire cpukit/libcrypt directory to contrib/cpukit/libcrypt and compiled from source for Sparc on my local machine and ran tests. Everything compiles, but as has always happened for me, 'crypt01.exe' fails testing. This occurred even prior to these changes so I assume it's something expected. The source code of the modified 'crypt.h' header is below:</p>
