Look out, Big Brother is watching you
As to conform to the requirements of the Homeland Security web browsers have been required to scan for suspicious activity for quite some time.
You should be aware, that because of this, your password (pin or phrase) could be compromised the first time you use it, and that it would not be necessary to decrypt the ciphered text with a "brute-force" attack.
Therefore it is pointless to discuss whether 128 bit encryption is enough or not.
A regular normal user would have nothing to worry about, but if your ambitions are of an illegal nature then you should be aware that encryption does not make it fail safe.
You have been warned.

Microsoft IE8
That means, your source text can be a hundred Kbyte or more. But, be careful. Nobody knows which other spyware were included meantime. I decline any guaranties.

Security Improvement
There is an ongoing discussion about an unused opportunity for improvement. To say it clearly, security has never suffered.
Nevertheless, effective Nov. 1st, 2005 I have changed the SDA generation tool slightly to further improve the security with gain for longer passphrases. Here are the facts:
The generated random sequence has two properties, polynomials and start status. Both are calculated out of the given passphrase and have a fixed 1 to 1 relation. But for some reasons it should be a 1 to many relation.
The drawing is only to give you an imagination how the random text develops. One starting point was always connected with one and the same polynomial that generates the sequence. Imagine that two different passphrases have the same MD5. (Btw, some guys are searching for collisions). Then the same random text would be produced although this is very improbable.
With only one additional statement in the polynomial selection algorithm the number of possible random sequences increases dramatically.
You can compare the change against the former version in the cracker award source file which will not be changed as promised.
If there are any doubts or objections, please let me know.

German Provider GMX has Removed the SDA Pages
To be independent of GMX in the future, the SDA location has been transferred to another server. But sure, the decrypted ftp user of SDA award's plaintext remains invalid because the site resides now at http://jgae.de/sda.htm.
Nevertheless, the bank account data are still correct. The amount has been increased to 1005,- Euro on reason of interest.

Communication Board
JavaScript SDA is a smart tool that protects private data in a public web. So only the authorized user (or a group of individuals) has access to these information simply by a web browser with knowledge of a passphrase. See the whole description on http://jgae.de/sda.htm.
