    boyd might be able to offer a safe replacement that's not subject
    to pointless controls.

you can certainly take my des from ftp://www.plan9.cs.su.oz.au/~boyd/des.msg
but it's not thread safe.  it assumes it's being called by a single
threaded program.  to fix it you need to have a per thread expanded
key.  all you need to do is to change deskey() to accept a parameter
for where to store the expanded key , rather than storing it in a
global static.  not real hard.
