Best encryption algorithm?

[alegator]

When I go to Roboform's options, under Security you can choose among the following encryption algorithms:
-DES
-3DES
-AES
-Blowfish
-RC6

By default it's set to AES. Is this the safest one? If not, which one? Thanks

they are all fine. it's only encrypting what is stored on your computer and any of those will stop anyone without an nsa badge.

AES with a 256 bit key is about as secure as you can get. http://en.wikipedia.org/wiki/Advanced_Encryption_Standard

alegator,

Given those choices, and with all other things being equal, I would use either Blowfish or AES.

The NSA believes AES is sufficient for protecting even top secret government documents (even when using only 192 of the possible 256 bit key size), and the NSA is very good at their job. As a rule, it's best to consider expert advice.

Blowfish is older, but (the last I heard) is still unbroken, which gives it more of a proven track record. Blowfish also allows a 448 bit key.

Of course, the best encryption algorithm in the world won't offset a weak password. If you google "strong password", you should be able to come up with a password that makes the most of whatever algorithm you choose.

But actually security level is determined by the weakest link. In case if strong cryptography is used, the weakest link is a password - it could be guessed much easily than encryption key. Computers become faster every year. And common practice is to increase complexity of password testing process in new versions of software.

Thanks everyone for their replies. Now, the way roboform works is that it stores the login information for a user's commonly accessed websites (username+password). It will only provide and fill the login info once the user logs in the program by means of a password that the user sets. So the question is, who cares how safe is the encryption method? I mean, if the program's access password is weak enough, someone can guess it or decypher it and then access all the encrypted login records stored in Roboform. ???
