I've reproduced on ubuntu and winodws with R3.4.3 When the filepath contains a tilde, the result is NA. But if the file path is expanded then the function works.
Example: tools::md5sum("~/.Rprofile") returns NA tools::md5sum(normalizePath("~/.Rprofile")) returns the proper md5 Perhaps this is expected behaviour because the documentation does say NA is returned for unreadable files, but I didn't think "~" would make a file unreadable to the function.
