I have a shell script as follows:

"set this_result to do shell script ("/usr/bin/openssl sha1 " & this_File) as string"

I need to know how to run the same routine on a text segment rather than on a file. Obviously, I'm inexperienced in working with Terminal-like commands.


1.
if openssl is in /usr/bin/, as it is, you don't need to give the full path to the executable and you can be in any directory. If you have an executable in a location that is _not_ in the path, then you execute it by prefixing ./ to the name

/usr/local/apache2/bin/./apachectl start

or

cd /usr/local/apache2/bin/ ; ./apachectl start



2.
You can read what is possible in openssl by typing 'man openssl' in the terminal

3.
You would run into problems if you used a string rather than a file because of encoding questions, so it's best to use files. The routine below shows how you might encode "abcde" in base64 by writing the string to a temp file, encoding it into a second temp file and reading this.


set s to "abcde"
set fin to "/private/tmp/in.txt"
set fout to "/private/tmp/out.txt"
set finmac to POSIX file fin
set foutmac to POSIX file fout
open for access finmac with write permission
set eof finmac to 0
write s to finmac
close access finmac
read finmac
do shell script "openssl enc -base64 -in " & fin & " -out " & fout
set encoded to read foutmac
