Temporarily read an encrypted file

Question

I want to store an encrypted .txt file (encrypted with a password, with AES for example) in the interal SD memory or µSD card of my phone. I want to be able to read it every now and then, but:




  • I don't want the unencrypted plain text file to be extracted and stored in the SD card (even as a temp file).


  • I don't want the unencrypted plain text file to transit via network (internet, etc.)




Is there a solution / app that would display an encrypted text file?



PS: I already tried full encryption of the phone, it's not what I'm looking for (other reasons, off topic here)



PS2: I don't want to use an online service

Thanks to this list of encryption apps, I found Encrypt It MkII which does exactly when I need:





The only problem I still have, is that I don't know how to decrypt it on Windows. (Does anyone have any idea for this?)



As an example the plain-text
