Can you bypass a password?

Question

On this site i downloaded a file, but its password protected. I have tried everything to get it including looking on the website. Does anybody know how to bypass passwords easily?

Answer 1

If you have 10/15 digits made up of letters [upper and lower cases], numbers and other special characters giving you anything up to 50 billion combinations, there is little chanch of cracking it even with a cracker program.

The trouble with passwords is that people are too complacent with them. A true password cracker who knows his/her job could get into most things within about 10 minutes. The number of people are so sloppy with their security and have not the first inkling about it is unbelievable.

Answer 2

No.

~END OF STORY~

Answer 3

Easily no.  Depending on the file type there are packages that you the brute force method, but it may take weeks or more to find the right password.  Longer if the user used a strong password.

Answer 4

No, they wouldn't have them if you could.

Answer 5

If they're using some javascript or less-secure password protection, you can probably find the password in the source code.

If it's PHP, it's a no.

Answer 6

Nope.

Answer 7

In short, no.

Encryption does not hide files, it just makes the contents unreadable. Many people encrypt their hard drives but the problem is if you are using Windows to encrypt all the files on your HDD the password is saved on the computer. The use of a third party encryption program is what any person should get.

File encryption aka cryptography, is the act of transforming sensitive data through an algorithm to make the file unreadable. Basically data is collected divided into chunks, put through separate algorithms, and put back together.

Example:

Lets say you want to encrypt "123" easy right.

We will first split this string up. (String refers to a instance of text)

So...

1

2

3

Put them through an algorithm

1+ 5 = 6

2 + 4 = 6

(3 + 13) / 8 = 2

Put them back together...

662

Now nobody will know what you wrote down unless they have the algorithm. It is much more complicated, but that is the idea.

Plain Text:

This text is readable...

Encrypted Text:

cMKRSA2qJUm9/8/4Lhstna+k+E0IyClKqCnkiP...

Now there are many forms of encryption:

The most commonly used is AES-256 bit encryption

+++This means there can be up to 32 characters in the password or 2^256 possible combinations

The newest is Diamond2-2048 bit encryption.

+++This means there can be up to 126 characters in the password or 2^2048 possible combinations

The only way to decrypt the file is:

1) If you have the original program that encrypted file,

2) If you have the algorithm used to encrypt the file,

3) You can reverse engineer the program used to encrypt the program in order the file the algorithm.

Even then, it is nearly impossible for an attacker to crack and decrypt the file.

Remember, the longer the key is the longer it will take to crack the file.

Even with these two types it will take 5.5 million years to crack AES (the standard in encryption)

Types of attacks (two most common):

Brute Force and Dictionary attack.

Strong Password:

1) Do not use words (hey, tree, feather, etc.

2) Mix upper/lower -case, with numbers and extra characters (a, A, 1, $)

3) Make the passwords long and unique

Good luck.
