[EXT] CryptoData

Post by pag77 »

Easily and quickly to encrypt / decrypt
For users: private messages via e-mail, blogs, social networks, forums, etc.
For webmasters: websites, images, photos, etc.
Support: Firefox, Thunderbird and SeaMonkey

https://addons.mozilla.org/addon/crypto-data/

This addon allows you to encrypt and decrypt the text: selected or manually entered text, as well as whole site
The encryption process is based on the US military standard Advanced Encryption Standard (AES)
https://en.wikipedia.org/wiki/Advanced_Encryption_Standard

JavaScript implementation (AES CTR) belongs to Chris Veness: http://www.movable-type.co.uk/scripts/aes.html

All encryption and decryption is performed only on the client side without the involvement of external resources or Web services.
Examples encrypting the selected portion of text and web-site:
http://www.s3blog.org/crypto-data/examples.html

  • For users:
    Simply select the plain or encrypted text in your web browser, open the context menu by clicking the right mouse button, and you can easily encrypt or decrypt any text.
    There is also a possibility of automatic decryption.

  • For webmasters:
    With this extension you can encrypt any content on the server, e.g. html, javascript or images
    Even if website uses a secure HTTPS-connection and access to his page requires HTTP-authentication, it does not mean that you are fully protected!
    There are many ways to steal your information, for example by using a proxy, sniffer or Trojan horse program (eg such as Zeus)
    But when you use addon CryptoData attacker could only get a set of useless characters!

    An example of the implementation of the encryption algorithm on the server side:

Using v. 2.08

Is there a way to encrypt text from another source (email, word processor, etc.)? Perhaps copying and pasting somehow (hopefully preserving links)?

Thanks!

Actually, I just did it by copying and pasting some text right here, then encrypting it. But is there a more general way to do this?

1a) open Context Menu (right click mouse) - click to menuitem "CryptoData"
or
1b) click to icon "CryptoData" in toolbar

2) will open small window CryptoData
3) put text and crypt or encrypt

Thanks very much for your extension!

I'd like to ask for a small change: would it be possible to move the encrypt/decrypt menu entry when you select text and right click below the first options? E.g. right now it looks like:

Image

With encrypt taking the place at the top replacing copy as the first item. This is really confusing to me as I'm used to right click > copy as a quick way to get some text.
Would it be possible to move it lower, like when you select a link?

Image

As I copy/select all way more than I encrypt/decrypt manually I think having the item in the middle/bottom part of the dialogue is much better.

You can use addon MenuWizard
https://addons.mozilla.org/addon/s3menu-wizard/
with it you can move or delete any menu items :)

Wow, thanks @pag77! I would still suggest the default be changed, but s3menu definitely serves as a stopgap solution!

Hello again!

I'd like to make another feature request:

Image

I'd like to ask that when the key is not known you'd have the option of covering the key input with asterisks, to protect against people peeking.
