Karrigell is a flexible Python web framework, with a clear and intuitive syntax Karrigell is a flexible Python web framework, with a clear and intuitive syntax.
Karrigell is independant from any ORM, database or templating engine, and will let the programmer choose between a variety of coding styles.
The package includes a powerful built-in web server, so theres no need to download, install and configure a separate one, and a pure-Python database engine, PyDbLite, which is used for the demos.
Karrigell can be configured to work with external web servers (Apache, Xitami, LightTPD); the scripts can use all the databases for which a Python API exists (sqlite, mySql, PostGreSQL, ZODB, etc)
A new application, InstantSite, is provided to easily create and edit MySQL databases and generate scripts that handle the usual CRUD operations on database tables. Take a look at the online Flash demo
To create dynamic pages, all you need to know is HTML and Python. You have the choice between different ways of mixing them.
In short :
- You can use ordinary Python scripts
- Karrigell services are Python scripts where each function matches a different URL : foo.ks/bar matches the function bar() in the script foo.ks (if no function is specified, the function index() is used)
- HTML inside Python is another form of Python script, where lines beginning by a string are sent to the browser as if there were a print statement
- Python Inside HTML is very much like PHP or JSP, HTML pages with Python code inserted between the tags
- You can use plain CGI scripts : see the documentation for the cgi module in the standard documentation
- Python code is executed in a "clean" namespace including HTTP environment, form fields and custom exceptions. When a form includes the field , the value is available in the script under the name _myfield
For authentication and session, two functions (unsurprisingly named Authentication and Session) can be used in scripts. Authentication takes an authentication test function as first argument, which checks if the AUTH_USER and AUTH_PASSWORD are accepted. Session() is used to initialize or retrieve a session object to which attributes can be set or read
The Include(file_or_script) function inserts the output of the script or file inside the output of current script ; this is useful for headers or footers for instance. If its a script it is executed in the current namespace.

An encrypted organizer for comprehensive protection of your personal data Never have data been handled and kept on your personal computer in such a intrusion-proof and safe way! Every conceivable means have been adopted to eclipse your data for unauthorized access. Nobody else but you should ever be able to view your personal data.
A number of measures have been implemented to achieve this unprecedented level of data security:
- Military-grade encryption
- Permantent (uninterrupted) database encryption
- Records encrypted and decrypted one by one
- Multiple keywords
Of course, all data stored with this organizer are spy-proof, even while you are working with your data: appointments, tasks, memos, financial transactions, passwords, credit card data etc. Nothing will ever leak out, all data withstand the most sophisticated cracking attempts.
The organizer includes the following sections:
- Calendar - for scheduling your appointments
- Contacts - keeps addresses and other data of your contacts
- Diary ? your most intimate daily log
- Task Lists ? check lists of what you should do
- Confidential Data ? for storing passwords and other sensitive data
- Memos and Notes ? whatever is noteworthy
- Budget Management - handle up to 3 private or professional budgets
- Import data ? from Outlook or Palm Desktop
The software is continuously updated and several new sections are under development:
- A Mail Client that keeps your emails out of reach for anybody trying to spy on you.
- A File Manager that allows you to encrypt every document and folder on your harddisks or other storage media.
- A PDA version of AbsolutePrivacy. There is a major risk of other people getting access to the data stored on your PDA in case you loose or forget it somewhere.
- A Synchronization Module to exchange data with Outlook.
- An Alarm for scheduled appointments.
Permanent Encryption
Some software products in the PIM category may allow encrypting the database at the end of the day when exiting the program. This requires opening the database before accessing it and leaving it open and vulnerable as long as it is used.
In AbsolutePrivacy, all information is permanently stored in encrypted form on the hard disk. There is no need to decrypt a complete database file before opening it.
By decrypting only one record at a time in volatile memory before displaying it on the screen (see below: Single Record Encryption), fool-proof data security is provided because encryption is executed continuously and reliably in the background, without the user ever having to care about it or having to remember encrypting the file after closure.
Single Record Encryption/Decryption
Every single piece of information (record) is encrypted with one out of tenthousands of passwords (see next paragraph). When reading a specific record (e.g. an address), it is copied to the volatile memory (RAM) where it is decrypted before being displayed on the screen. On the harddisk it remains stored in encrypted form.
The plain (decrypted) information is NEVER EVER stored on the harddisk or any other storage device, not even partially. If the record is modified, it passes the encryption filter before being written back to the harddisk. Nobody will ever be able to hack or to decipher any info by analyzing the harddisk, not even with the most sophisticated methods available.
Thousands of Encryption Keys (Passwords)
While the database is opened with one main passphrase (the Master Passphrase), internally, tens of thousands encryption keys (composed of random characters) are created with a special algorithm and used to encrypt every piece of information individually.
The likelihood of the same key being used more than once in 50000 records is almost nil. In other words, in an average sized database, all records are encrypted with different, individual keys.
Highly secure Encryption Algorithms
The 128 ? 256 bit encryption algorithms are similar to those used by the military and are among the most secure.
It has been calculated that the 128 bit encryption algorithms are so strong that it would take a network of supercomputers significantly longer than the age of the universe to crack the code (millions of years), not to speak of 192 and 256 bit encryption, used extensively in the program, too.
Since every record is encrypted with an individual password, in the utopical event of someone succeeding to break the code, only the information contained in 1 single record would be uncovered.
If you activate this function, the program will be closed automatically after a customizable period of 1-15 minutes of inactivity. This prevents you from inadvertently forgetting to close your database when leaving your workstation.
Alternatively, you can opt for not closing the program, but to only hide the data you marked as private or to close the active section (e.g. the Calendar or the Diary) when the program has been idle for some time.
Hide Private Records
This function provides an additional level of security: records flagged as private can be hidden when someone else (e.g. your secretary) is allowed to use the application.
Optional PIN (secondary passphrase) to access applications
When used by more than one person, the administrator/owner of the database file can protect single sections (like the budget or the diary section) additionally by defining a PIN code or, conversely, give another person (e.g. the secretary) exclusive access to a specific section.
In combination with the ?Hide Private Records?-function, the PIN enables for instance the secretary to use the budget and the address/contact section, without being able to see the private records. No other person trying to gain information will manage to open any of the PIN-protected sections.
Passphrase Entry
Minimum passphrase length: 8 characters. The more characters, the lower the risk of cracking the passphrase (8 characters reflecting the available keys of the keyboard would theoretically require a mean of 92^92/2 attempts to open the database; therefore, it is important to use a relatively difficult to guess passphrase, the longer the better, preferably containing non-alfanumeric keys).
Forced delay between passphrase inputs: 2 seconds (this makes it virtually impossible for automatized brute-force attacks to open the database)
Maximum number of retries: after 3 wrong passphrase inputs, the application is closed. Reopening the program takes some time, which is an additional protection against brute-force attacks.
