Hi there,

I m using 1.1 release.

I am facing a problem, i would like to discuss.

I want to use single keyPair so i stored that keypair in my database.

Every time i have used this ‘stored keypair’ for encryption and decryption. Everything was worked fine.But the only problem is when i restart my server, then i m unable to use the ‘stored keypair’ again.After restart it started giving me exception.

Is it related to session or something?

Thanks,
Ravi.

Humm it’s removed some of the code;

while (strlen(Data) greater than 30 OR strlen(Data) less than 2)
{
Data = jCryptiondecrypt(Data…

I’ve got an annoying problem, I’ve hardcoded a key into a text file for the javascript client and into the PHP code too (I know it’s not a good idea but it’s a long key and processing time is greatly reduced). Sometimes when I submit data, it works fine, other times it won’t work at all, and I’m logging the data it recieves and seeing no differences (I’m submitting the data). If however I replace the decryption code with this;

while (strlen($Data) > 30 || strlen($Data) decrypt($Data, “*snip*”, “*snip*”);
}

After about 30 seconds of processing, it eventually spits out the correct string. I’ve looked and looked but I’m still unable to find the cause of it, would you happen to have any idea?

Totally agree to Vahe Pezeshkian post, please fix the issue with the IE and add a “var” before result-variable.

Nice library!

Besides what Marcelo said about server-side php script, there is some point about client-side javascript.
IE will not be able to interpret the library correctly if you do not correct line 464 in jcryption.js file:

function biMultiplyDigit(x, y) {
var n, c, uv;

result = new BigInt(); =>> var result = new BigInt();
n = biHighIndex(x);
c = 0;
for (var j = 0; j >> biRadixBits;
}
result.digits[1 + n] = c;
return result;
}

You should add “var” keyword else you’ll get object does not support method or property error in Internet Explorer.

Great library

Hi Daniel,

First: Great plugin for jQuery, maybe one of the best I ever used!

But I’ve figured out that jCryption won’t work if you use a as submit button (it takes bout two or three hours to find out that )
It would be nice if you add the type=”image” submitbutton to the next version if jCryption.

Kind regards,
Tobi

split() ha sido declarada OBSOLETA desde PHP 5.3.0.
en la linea 638:
$blocks = split(‘ ‘, $encrypted);
reemplazar por:
$blocks = explode(‘ ‘, $encrypted);
