Bob, Thanks for responding. I've tried the functions in bcrypt, and get, for example,
> infl <- 'path.to.the.encrypted.file' > junk <- 'the.password' > foo <- readLines(infl) Warning message: In readLines(infl) : incomplete final line found on 'path.to.the.encrypted.file' > tmp <- checkpw(junk, foo) Error in hashpw(password, hash) : Invalid salt Thus demonstrating that I don't know what I'm doing. If it's easy to expand, as you mention, I would indeed appreciate it. -Don -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 11/7/16, 5:29 PM, "Bob Rudis" <b...@rud.is> wrote: >Perhaps https://cran.r-project.org/web/packages/bcrypt/index.html >might be of assistance. > >If not, drop a note back to the list as it'll be trivial to expand on >that to give you an R alternative to Perl. > >On Mon, Nov 7, 2016 at 5:47 PM, MacQueen, Don <macque...@llnl.gov> wrote: >> I have a file containing encrypted contents.
