Plugin: XOR Encryption

rex_encdec_xor , document and sample capx are included.

Encrypt or decrypt string by XOR Encryption algorithm.

Is this suitable to encode data to be saved to web storage then decoded when brought back in?

When i look at data stored in localstorage file on my PC i can see the contents. It would be nice to encrypt this so it cant be altered externally.

Thanks

Yes, it could. Here is a sample capx.

Hey thats great, thanks for the quick reply too

spongehammer

I found a way to compress string. User might use it with this XOR Encryption, like this sample capx.

( Well, the result of string compression might be a kind of encryption. )

rexrainbow

I think the encryption alone is probably good enough without compression, plus i am guessing the compression will slow down the transfer of data to and from webstorage.

You little beauty, Just what i was looking for!

Thankyou So much!

Hi rex

first time...very thanks for your plugins .

Its possible the same in AES algorithm....

Thanks!!

It is possible, here is a javascript version of AES encrypt/decrypt

But I had no time recently, sorry.

Thanks rexrainbow ...but i do not know how convert this in plugin.

When testing the limits, I found out that really long keys (sometimes longer than 110 chars, sometimes longer than 256 chars, but for sure at 2048 chars) all produce the same encrypted value. That means anyone can decrypt them using any key long enough (doesn't have to be the same length, just very long).

Where and why is this limit?

Sorry I don't have time to review this plugin recently, will try it later.

Hello, rexrainbow

Why I can't find this object on New Object list?

I can load the sample just fine without error but it's still not showing up... even if I search the name.

I'm using Build r244.

"Simple XOR Encryption"

Excuse for my English, the new version of a plug-in gives java script error message so I removed a flag 'pf_deprecated' from the old source code and use the old version (which not simple).
