Is it possible to unencrypt data?

Question

I mean there might be some possible way to determine what the original data may have once been by analyzing data directly yourself using some mathematical, .

Is it possible to decrypt encrypted data?

No, not with the current hardware if a good encryption method was used and the key (password) was long enough. Unless there is a flaw in the algorithm and that you know it, your only option is to brute force it which might takes hundred of years.

Is it possible to break the encryption?

Today's encryption algorithms can be broken. Their security derives from the wildly impractical lengths of time it can take to do so. Let's say you're using a 128-bit AES cipher. The number of possible keys with 128 bits is 2 raised to the power of 128, or 3.4x1038, or 340 undecillion.

Can encrypted data be recovered?

Depending on your computer's encryption software, you may be able to retrieve data by transferring the original drive's security certificate to another drive, allowing for appropriate decryption with Encrypting File System (EFS) and some other encryption technologies.
