Uh... I must be missing something, because I'm pretty sure those are hash functions and thus can't be decrypted?

[Mackan90096]

they can.

use this for binary/hex:

Oh aren't you cute with your little lmgtfy. Technically speaking, you're not decrypting them, you're using rainbow tables.

Oh...?

A hash is designed to be one way. For example a SHA256 hash algorithm will turn a character sequence of any length into an alphanumeric string 64 characters long. The 'decryption' as you put it is, as D3matt stated, just simply a rainbow table lookup. A rainbow table is just a lookup table containing a list of words/sentences with their respective hash. As such this is why we use a SALT on data, adding a salt reduces the likeliness of the particular string being in a rainbow table, which means that they would have to bruteforce the hashed string.

Now for example, attempt to perform a rainbow table lookup on a website(s) of your choosing, and see what is returned... It is a SHA256 hash of some data with a random salt.

EDIT: Actually even try to crack the SALT that the above hash was made with (note the salt is a SHA256 hash of some random data)

Yes, hashes cannot actually be decrypted. These sites are just database lookups.
Another thing to add to OiginalBit's comment is that these 'decrypter' sites usually have sister sites that let your encrypt data.
When a user encrypts through it, the data is saved in their database which is used by the 'decrypter' site.

Oh... Well. Learning more 'bout computers.
