Automatically decrypt and run an encrypted bash script without saving decrypted file to file system

I have a shell script that produces sensitive content when run. It sits on a box that only a few users have permissions to access. However, I have also added layered obfuscation to prevent unauthorized usage, via the following: - script must be run as root - script must be passed specific command line arguments to produce any output - script has been encoded by the shell compiler "shc" to mask facts #1 and #2 from normal users (those who would not know to use TRACE or STRINGS to still view the actual code). To then add a layer of actual security to protect again more advanced users and system admins, I have also encrypted the script with gpg. My question is -- Is there a gpg command (or other encryption method) that I could run which prompts for the decryption passphrase, and decrypts the script and runs it in memory only (without saving the decrypted version of the file to the file system)? I realize that sensitive information may still exist in unprotected memory while being executed, I'll address that separately.
