What are encryption keys?

What are encryption keys and how do they work?

An encryption key is typically a random string of bits generated specifically to scramble and unscramble data. Encryption keys are created with algorithms designed to ensure that each key is unique and unpredictable. The longer the key constructed this way, the harder it is to break the encryption code.

What is meant by an encryption key?

In cryptography, an encryption key is a variable value that is applied using an algorithm to a string or block of unencrypted text to produce encrypted text or to decrypt encrypted text. The length of the key is a factor in considering how difficult it will be to decrypt the text in a given message.

Is an encryption key the same as a password?

An encryption key is not the same as a password. The main difference between the two is that a password is created, read, and remembered by a human user, while a key is used by the software that implements the algorithm, meaning it does not have to be readable by a human.

Where do I find the encryption key?

The default encryption key may be located on the bottom of your router or in the manual, depending on the router manufacturer. You can locate the encryption key when you log into the router setup page, if you have created your own encryption key.
