From the developer:
KodeFile lets you encrypt any photo, video, or document with a few simple clicks. KodeFile’s Key On Demand Encryption (KODE) generates and stores a unique key for every file you encrypt. Then, on demand, it shares the secret keys with your confidants so that they can decrypt.
You may want to check out more Mac applications, such as Secret Folders, Ghost or Rohos Logon Key, which might be related to kodefile.
