License Manager

Generate and validate license keys.

Note

This was originally written while DropPy was a commercial app and Fastspring was used to purchase licenses.

Now the app open source, so I don't need this any more. Feel free to use, probably generate your own DSA keys though.

Generating DSA keys

Info:

OpenSSL is already installed on macOS
These are 512bit DSA keys

Ran the following commands in this order:

openssl dsaparam -out dsaparam.pem 512
openssl gendsa -out privkey.pem dsaparam.pem
openssl dsa -in privkey.pem -pubout -out pubkey.pem

Documentation:

https://github.com/glebd/cocoafob/readme.md
Section "Generating Keys"

Came out with those three files:

dsaparam.pem
privkey.pem
pubkey.pem

CocoaFob

Version

Cloned the repo at https://github.com/glebd/cocoafob on 2017-09-20
Not very active, the last commit was 2 years ago
Used the files from there (subfolder "swift3/CocoaFob")
A zip of the repo at that point in time is stored in "Resources"

cocoafob-keygen

I could not get this to run on my machine (macOS 10.12, Xcode 9)
So I built my own version
