Step a)
Create a file with the passphrase in a single line with your favourite Editor.

Step b v1) (Simple symmetric encryption)
gpg -c <file>

Step b v2) (Whatever you like best)
gpg <Whatever you options are> <file>


Done. You can use the resulting file as a keyfile.

Real Programmers consider "what you see is what you get" to be just as 
bad a concept in Text Editors as it is in women. No, the Real Programmer
wants a "you asked for it, you got it" text editor -- complicated, 
cryptic, powerful, unforgiving, dangerous.
