I'd like to research on the available cryptanalysis tools for algorithms such as AES, DES, RSA, RC4, Blowfish and the like.
You can check the following website

Additionally, you can read the following paper
Shujun Li, Chengqing Li, Guanrong Chen, and Kwok-Tung Lo3, Analysis and Cryptanalysis of a Selective Encryption Method for JPEG Images
As far as I know, there's no universal automatic cryptanalysis tool to tell you "how secure this algorithm is". Especially, you have mentioned several types of cipher: AES/DES (Block), RSA(Public Key) and RC4(stream). Blowfish is also a block cipher, but due to the key-dependent S-boxes, many attacks on block cipher may not work on Blowfish.
There's one thing that's universal---brute force attack. You don't need tools for this; just take a look at the key length, and make sure brute force search is infeasible.

You might be interested in this site, which provide several cryptanalysis in a platform. However, this is mainly for e-learning purpose; it doesn't contain much cutting edge technology.
This question is very broad, and for the mentioned algorithms, it takes a significant amount of time to acquire a full understanding of different attack procedures. As a good starting point, I suggest you refer to the websites of CRYPTOREC, NESSIE, eSTREAM and CAESAR.
