Set up wija (2) - import the system's public key

The system's public key is used for checking if correct software is obtained when they are automatically updated1.

1. Guidance

When you start wija for the first time, if the system's public key has not been imported to the key rings, wija will automatically import it. The following window appears.

[Imported system's public key]

See whether the two fingerprints2, one on the displayed window and on in the above picture, are the same (it will suffice if you check whether the two color patterns look alike). After the fingerprint is confirmed, digitally sign the system's public key.

2. Sign the system's public key

After clicking on "Sign" button, the following window appears.

[Signing a public key]

Enter the passphrase, and click on "OK".

The programs of wija and its plugins distributed from Media Art Online are digitally signed which can only be verified with the system's public key. If other parties would like to distribute their own versions of software, they too can distribute their own systems' public keys to benefit from the automatic update feature (the first distribution needs to use other methods than automatic update, such as downloading from the web).

Since a public key is too big for a human being to handle directly, it is very cumbersome to confirm that a public key they have obtained is genuine. For that sake, a public key data is compressed to the form of 40 digits (because it is in hexadecimal, the numbers may contain alphabets between 'A' and 'F'). This is called the fingerprint of the public key. The fingerprint is calculated in such a way that if two public keys are slightly different, the resulted fingerprints differ widely.
