Lisa LCD 85
Important:
Although the mp3 format is used in our examples, Streamit’s encryption technique is independent of
the file format.
The encrypted filename will be the same as that of the original file, but with all lower case characters
and the file extension .enc.
Once the files have been encrypted, you must not modify the filename or extension of the encrypted
files anymore.
Encryption key(s) are generated using the Streamit Card and Scheduler Toolkit .
The encryption key is loaded to the Lisa device using the Lisa Configuration Tool .
12.2.1
Generating an encryption key
The Streamit Card and Scheduler Toolkit is used to generate the encryption key(s). The full version of the
Streamit Card and Scheduler Toolkit is required to encrypt tracks, the free version does not offer that
functionality. Ask your sales contact at Streamit for details of the SCS Toolkit.
Some documentation or software may refer to the 'decryption key'. This is exactly the same key as
the encryption key.
To generate an encryption key you choose the option 'Generate (CARD) Encryption/Decryption key' from
the File menu. A dialog window opens, allowing to choose the file name and location of the encryption
key. We recommend that logical names are used for the keys and discourage the generation of many
keys if not needed.
12.2.2
Loading the encryption key into the Lisa
To load the encryption key to Lisa devices, use the Lisa Configuration Tool and follow these steps:
Press on the “Load decryption key” button, browse to and select the encryption key (*.bin) to load to
your device.
Press on the "Upload key" button, the upload will start.
