copied to clipboard

macOS
Prepare signing with EdDSA signatures:
Output:
A key has been generated and saved in your keychain. Add the `SUPublicEDKey` key to
the Info.plist of each app for which you intend to use Sparkle for distributing
updates. It should appear like this:

<key>SUPublicEDKey</key>
<string>pfIShU4dEXqPd5ObYNfDBiQWcXozk7estwzTnF9BamQ=</string>
copied to clipboard
Change the file macos/Runner/Info.plist as follows:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>

...

+ <key>SUPublicEDKey</key>
+ <string>bHaXClrRGMmKoKP/3HJnr/jn2ODTRPAM3VZhhkI9ZvY=</string>
</dict>
</plist>
copied to clipboard
Windows
Prepare signing with DSA signatures:
Output:
Generated two files:
dsa_priv.pem: your private key. Keep it secret and don't share it!
dsa_pub.pem: public counterpart to include in youe app.
BACK UP YOUR PRIVATE KEY AND KEEP IT SAFE!
If you lose it, your users will be unable to upgrade!
copied to clipboard

command will generate the private key (dsa_priv.pem) and the public key (dsa_pub.pem) for you. Please Back up your private key and keep it safe, Add your public key to your project either as Windows resource.

Change the file windows/runner/Runner.rc as follows:

...

+/////////////////////////////////////////////////////////////////////////////
+//
+// WinSparkle
+//

+// And verify signature using DSA public key:
+DSAPub DSAPEM "../../dsa_pub.pem"
