Encryption cracking tools or sites?

Hey Guys,

Can any one help me with any tools or sites which can report the strength of any Encryption program.

Experts, please let me know.

 

I seriously doubt that anyone here will guide you to decryption tools, since that's the antithesis of privacy. This forum is all about maintaining and heightening privacy and security, not undermining them. As for the relative strengths of various cryptographic tools, I've seen them reported here occasionally (but long ago) as links to or snippets from reviews. You'd be better of with a Google search, I believe.

 

There are many characteristics determining the strength of encryption:

-The secrecy of the key.
-The difficulty of guessing the key or trying out all possible keys (a key search). Longer keys are generally harder to guess or find.
-The difficulty of inverting the encryption algorithm without knowing the encryption key (breaking the encryption algorithm).
-The existence (or lack) of back doors, or additional ways by which an encrypted file can be decrypted more easily without knowing the key.
-The ability to decrypt an entire encrypted message if you know the way that a portion of it decrypts (called a known text attack).
-The properties of the plaintext and knowledge of those properties by an attacker.

and only a few of those can be expressed mathematically. So you may have a hard time finding a purely objective comparison. (as usual )

Regards,

Pieter
