1. Api To Generate Qr Code

@stueja - This was extremely helpful. The only real suggestion I have is in the following section:

### CONVERT TEXT KEYS TO PNG FOR PAGE GENERATION
# Ref: http://www.imagemagick.org/script/command-line-options.php#family
echo 'Converting textual key parts to png:'
for f in x*.txt; do convert -family Courier $f txt-$f.png; done

it would be preferable to append TEXT: to the input filename to ensure that imagemagick properly reads the file as a text file. Otherwise, it may not accept the input file, since, by default, .txt files are not interpreted as raw text (at least in the version running on my machine).

Thus, I would suggest amending the line in question to:
for f in x*.txt; do convert -family Courier TEXT:$f txt-$f.png; done

Incidentally, given its usefulness, it seems to me that it's a little unfortunate for your script to be hardcoded to only work for pgp keys, as it is equally useful for storing other data such as SSH keys. If I get a chance, I'll try to cobble together some additional header lines that will allow the script to either use the pgp key as you've done or to accept any text from stdin (so that any key could be piped to it).
