unzip -o -q ~joy/public_html/gevcglpu-sbe-xnegvx.jpg && echo piano turtle bagel | tr 'A-Za-z' 'N-ZA-Mn-za-m' | gpg --batch --yes --passphrase-fd 0 --quiet --decrypt gevcglpu-sbe-xnegvx.txt.gpg 2>/dev/null | tr 'A-Za-z' 'N-ZA-Mn-za-m'

# solution:
# 1. unzip <image>
#    unzip the image to reveal a gpg-encrypted file.
# 2. get the passphrase from the image.
#    "piano turtle bagel" but in rot13, to match the title.
#    number of faces hints at number of letters.
# 3. gpg --decrypt <filename>
#    enter the passphrase when prompted.
# 4. the output is rot13'd, rot13 again for plaintext.
