This site, the encrypted forum with open source code, provides more secure private communications between people. All messages are transmited by the internet and stored in the database in encrypted format. All mathematical operations are executed by client (internet browser), not by server. For text encrypting this forum uses AES (Rijndael) 256 CTR (Counter mode), symmetric military-class encryption (USA) 2012, and for passwords exchange between users - RSA (Rivest-Shamir-Adleman) 768-2048, one of the best asymmetric ciphers at present time (2012). Here You can create Your own forums and discuss with Your friends any topics securely. Anybody (even administrator) cannot read Your closed messages. Register and join the encrypted community!

I have decided to improve CryptBB.

Major change: Added VEIL message veilization.

What is VEIL?

Enveil converts the Base64-text to the random text with simple sentences. Deveil converts this generated text to the Base64-text. Enveilized text hides the Base64-text.


For example. We need to post securely the message:

How are you?
Click to expand...

We encrypt this message with AES-256 CTR cipher and password 12345 (without capsulation) and get the Base64 (custom) text:

7gCYj.pd8FGZe,.o!dbTAadJUFo=
Click to expand...

Now we enveilize this Base64-text with first VEIL Javascript function by internet-browser and get the human-readable post:

Scott has pointed to the battery. Further Jason and Katy, turning the packet, have painted Steve's bottle. And Angela, losing the journal, has wanted Terry's orange. Suddenly Rebeca, painting Jeffrey's document, has acquired Jeff's jar certainly. But Jack said: "Amanda has reminded of the tube!"
Click to expand...

Then we transmit this post to the WEB-server. CryptBB deveilizes this post with first VEIL PHP function and saves the deveilized Base64-text to the database. When we read the encrypted topic, CryptBB, using the second VEIL PHP function, show to us the human-readable post. At the end, we deveilize the post with second VEIL Javascript function and decrypt the Base64-text with AES-256 CTR by internet-browser. Now everybody, who knows the password, can securely read the source message.


Opinions?

New version: 3.14.2.1. Major change: Added support of PHPSECLIB + JS (to encrypt passwords of accounts on data transmiting).

Site: http://cryptbb.site40.net

The site has simple structure:
- Forums → Forum → Topic → Post
- Forums → Users
- User profile → Private messages → Passwords exchange

Forums contain topics, topics consist of posts. All topics have passwords, all posts are encrypted; depending on options, forums also can have passwords for encrypting of names of topics. Author of the post can delete his post; topic starter can delete any post in his topic and the topic self; forum creator can delete any post or topic in his forum and the forum self; administrator can delete any post, topic or forum.

Function of restriction of rights for users and guests to view, read and write in forums and topics is supported. Module "Users" displays numbers of all registered members to set the rights for concrete users in corresponding section.

Module "User profile" allows to change the password, and also to move to the module "Private messages", where members can exchange between themselves passwords of topics or forums.

It is allowed a short links to the topics, for example, http://cryptbb.site40.net/?t=9
In this case the program realizes automatical pass from main page of the forum to the topic with number 9. On registration and login the redirect is kept.

Besides, for secure increase, offline tools to generate the random passwords, to create the keys and to encrypt and veilize the messages are created.

Opinions?

Fourth open source version: 4.15.1.25.

Major changes: ASYM asymmetric and SYMM symmetric encryption utilities was upgraded, SCRAMBLE scrambling of messages was added after CAPSUL capsulating.

Official site: http://cryptbb.us.to

Version 5.15.5.9.

User "crapspacle" asked about image posting, so encrypted files attaching to the messages was realized. BB-codes are supported.

Take a look the example of encrypted torrent forum:
http://cryptbb.us.to/?t=3
Password = 12345

Version 5.15.6.2. Smileys are supported. :)

User "Sophia Kiss" wrote and shared the simple open source win32-application to locally convert Base64-text of decrypted file, attached to the message, to a binary data and save it to a file.

This application can be used to write attached non-image files (for example, decrypted torrent-files) to a disk. The software can run under Wine or be ported to Linux from sources.

The new version of CryptBB is released: 6.16.12.31
http://cryptbb.us.to/

Major changes: CAPSUL was simplified up to NOISE, SCRAMBLE was simplified up to SWAP. The offline utility SIGN was created.

Now the application can digitally sign and verify the text, the files and the sites using HTML+JavaScript only, for example:
Code: 
-- BEGIN AUTHORIZED FILE --
Signature type: UTF8(TEXT) -> RSA-PSS(E=65537, HASH=SHA256)
Verify file: http://cryptbb.us.to/soft/6.0/sign/file/
---- BEGIN SIGNED FILE ----

File name: cryptbb.zip
File size (B): 162064
File hash BASE64(SHA256(FILE)):
GlSyBwxFMSHbdvTRM2a+HZyQOFsc9hOKVqoZLcSgF2c=

Name of signer: VanDerSaAr
Date of signing: 2016-12-31
Comment to the file:
CryptBB-6.16.12.31

----- END SIGNED FILE -----

Yes, I've heard of such stories. It's nice if the app or any utility is useful.

Today with the increase in Data Generation, companies are fully dependent on cloud services to maintain, store, process and manipulate their data. Cloud computing is the hottest topic in the market as it provides various benefits to the user apart from storing and maintaining data. Cloud computing is the best way to save money. It eliminates the requirement to set up an infrastructure and is fully secured as compared to traditional means of storing data. And the main issue of storing big data is also solved by cloud computing. Today there are various cloud service providers in the market and the widely used amongst them is AWS.
