These are created by making a hash of the file. This is like a fingerprint of the file: it is generally a lot smaller than the file itself. It should not be possible for two different files to have the same CHK; a CHK uniquely identifies a file (assuming that SHA-256 is not broken!).

~1) The first part, SVbD9~HM5nzf3AX4yFCBc-A4dhNUF5DPJZLL5NX5Brs, is the actual hash of the file.
- The second part, bA7qLNJR7IXRKn6uS5PAySjIM6azPFvK~18kSi6bbNQ, is the decryption key that unlocks the file (which is stored encrypted).
- The third part, AAEA--8, is something to do with settings such as cryptographical algorithms used.

All files within Freenet are identified and requested by a key, in a similar way that normal websites are identified by a domain name. You don't really need to know the technical details to use Freenet; tools such as jSite will sort it all out for you.
Content Hash Keys are for files that aren't going to change. For example: mp3 files. They look something like this:

This random-looking string is the Content Hash Key (CHK) of the line of text this is a test, and is telling you the address that other people can use to access this file in Freenet. You can see that it consists of three segments, separated by commas:

This example will add a small text file to Freenet using the Content Hash Key to identify it. We will use the basic telnet interface to Freenet for illustrative purposes but you can use a more featured site creator like jSite.

CHK: Content Hash Keys
All files within Freenet are identified and requested by a
key, in a similar way that normal websites are identified by a domain name.
Content Hash Keys are for files that aren't going to change. For example: mp3 files.
These are created by making a
hash of the file. This is like a fingerprint of the file: it is generally a lot smaller than the file itself. Although it's possible two files may have the same fingerprint, or hash, it's very unlikely.
This hash is used as an index to the file, in a similar way to the address, or URL, or a standard website. The CHK key is generated automatically, so it won't look as user-friendly as a domain name. For user-friendly keys, have a look at
KSK pages
Example
This example will add a small text file to Freenet using the
Content Hash Key to identify it. We will use the basic
interface to Freenet for illustrative purposes but you can use a more featured site creator like
jSite.
At the command line, type the following to access Freenet's command line interface:
You should be presented with a list of options. Type the following and then press
Enter:
after a short while (be patient, it could take a minute or two) it will return this:
URI: freenet:CHK@SVbD9~HM5nzf3AX4yFCBc-A4dhNUF5DPJZLL5NX5Brs,bA7qLNJR7IXRKn6uS5PAySjIM6azPFvK~18kSi6bbNQ,AAEA--8
This random-looking string is the Content Hash Key (CHK) of the line of text
this is a test, and is telling you the address that other people can use to access this file in Freenet.
To exit from the telnet interface, press
Ctrl-] and press
Enter, then type
quit and press
Enter.
To verify your file exists in Freenet, open a web browser and go to:
http://localhost:8888/CHK@SVbD9~HM5nzf3AX4yFCBc-A4dhNUF5DPJZLL5NX5Brs,bA7qLNJR7IXRKn6uS5PAySjIM6azPFvK~18kSi6bbNQ,AAEA--8∞
You may get a warning come up at first, but just tell the browser to open it as a plain text page. If all goes well, you should see the text you have just inserted to Freenet.
