Official binaries are codesigned with a self-generated key (no certificate authority involved). The corresponding security certificate has the following SHA-1 thumbprint: 48 a1 4a 81 51 75 ad c0 22 74 d3 c4 57 37 b6 79 a1 73 d6 78. Click here to download the certificate.

More Robust HTTP Download

If your browser fails at downloading large files (it happens), you can employ the EepGet class of I2P to handle HTTP-downloads for you. There's a script in your I2P installation directory named "eepget" for this. You can access it through the command prompt of your operating system. Usage example (Windows):

C:\Program Files\i2p\eepget.bat -n 2 -o "C:\DestFolder\"

This will make I2P download the file "" and put it into the output folder "C:\DestFolder", retrying two times before giving up. The I2P router must be running for the script to work. Don't rely on the script to create the output folder for you and keep in mind that URLs are treated case sensitive. Usually the script doesn't give you any feedback, but the file will appear in the output directory after a few moments (depending on how long the download takes).

Download per P2P

In addition to the HTTP method above, you can try to download the latest version (1.4.27) of Nachtblitz using iMule or Nachtblitz from within the invisible eD2k network. The most secure way of doing this is to use the following official eD2k links and a Nachtblitz client for the download, since the download will then rely on a secure hash (the TAICH hash). In any case, especially if you're not using trusted links or if you're downloading with iMule, you should verify the PGP signature when the download has finished. If you don't know how to verify PGP signatures, ask someone on the I2P forum how to do it. If this all sounds too complicated to you, use the HTTP download to be on the safe side.

You can configure Nachtblitz to associate itself with eD2k URIs on the options window (on MS Windows only), so that your browser will pass clicked eD2k links to Nachtblitz automatically.
