This is a re-cast of my previous Key Maker Puzzle.
I've created a simple substitution cipher by taking a 13 letter phrase with no repeated letters and writing the remaining 13 letters of the alphabet in alphabetical order under it. For example:
To employ the cipher encode letters by performing vertical substitution. P becomes D, O becomes E, etc. The word PUZZLE encodes to DFTTHO.
I wrote a small program to generate this puzzle by randomly selecting appropriate words and then solved it myself manually to ensure that it is in fact reasonably solvable.
So here's your puzzle. The four words below have been encoded using certain key phase as shown above. Can you deduce key phrase? The key phrase consists of a six letter word followed by a seven letter word. No letters are repeated.

Enter the 13 letter key phrase into Certitude to get the cache coordinates. Enter only alphabetic characters. Do not use any spaces or punctuation. For example if the key phrase was 'public servant' enter 'PUBLICSERVANT'.
