D-cm & DCrypt

[Kruptein]

Hello all,
I'm developing d-cm, d-controll manager.
It's a controll manager for web-programmers.

It's a GUI built in the python language with wxPython.
It has a file-manager,mysql-manager,ftp-manager,text-editor and a terminal window all in one program. You don't longer have to have a lot of different applications opened.

You can find more info @ d-cm - Project Hosting on Google Code


Another program I'm developing is DCrypt, this will later on be integrated in d-cm.
It's an encryption and decryption tool that uses a special way of encrypting which makes it almost impossible to hack, (unless you do a dictionary attack, but this is the case with every tool)

DCrypt is also on googlecode: kruptools - Project Hosting on Google Code -> downloads -> dcrypt.py


please tell me what you guys think about it.

Sorry to burst your bubble but I am pretty sure that DCrypt is easy to hack. And also, the term isn't hack, but break. An interesting idea though

[Kruptein]

Which kind of tool or method are you thinking about, cause i really don't know how?
if I post here a sentence with a random password you would be able to get the original sentence?

[lthreed]

Most likely yes. As a general rule, any classic cipher is insecure. And i am pretty sure that each of those ciphers would leave a pattern that would distinguish them. I would need to look into your program in more detail but then I could probably crack it. I do like the idea of varying the encryption method based off the password though. And also remember that a break can be based off knowing the input and the output and using that to discover the key

[Kruptein]

Okay, your indeed right about the classic encryption systems, (although I think that if U shift enough times between them, it would be **** hard).

But it is also **** hard to find an encryption method that can be decrypted easily too.
md5 and sha1 are strong encryption methods, although md5 is already hacked, it still is almost impossible to decrypt it.

Do you know some?
(PGP might be one)

[lthreed]

MD5 and SHA-1 aren't encryption functions, they are hash functions. They are not supposed to be easily reversible. For strong, secure, and fast encryption check out AES. This article is useful Advanced Encryption Standard - Wikipedia, the free encyclopedia. A good implementation of AES for python is included in PyCrypto

[Kruptein]

Yes I found an interesting module for python with AES,DES,...
I'm going to work on it this weekend =)

[lthreed]

Awesome! Send the link when you finish up

[Kruptein]

MWAHAHA I successfully integrated AES into DCrypt ;D

After some struggle with letting AES be compatible with other encryption methods, I made it =)

You can download this version of DCrypt @ googlecode it will be called dcrypt.py

[lthreed]

Nice, my only advice would be using AES in CBC mode or CTR mode. It will only make it more secure
