1.3.1 - Encryption & Hashing

What is encryption?

• Data is altered to make it easy to read

• Transforms data to make it easier to enable hackers to access it

• Transform data from one form into another

• Data is altered to prevent people from reading it

Original data ready to be encrypted is called

• Plaintext

• Ciphertext

• Cipher

• Key

Encrypted data is called

• Plaintext

• Ciphertext

• Cipher

• Key

Algorithms used to encrypt data is called

• Plaintext

• Ciphertext

• Cipher

• Key

Information to lock or unlock the message is the ...

• Plaintext

• Key

Symmetric encryption ..

• Uses the same key to encrypt and decrypt data

• Is very secure

• Is not very secure

• Uses different keys to encrypt and decrypt data

Symmetric encryption ..

• Sends out new keys can be sent out each time there is a new message

• Interception and duplication of the key can happen

• Is not very secure

• Uses different keys to encrypt and decrypt data

Asymmetric encryption ..

• Sends out new keys can be sent out each time there is a new message

• Interception and duplication of the key can happen

• Is very secure

• Uses different keys to encrypt and decrypt data

Asymmetric encryption ..

• Uses 2 different keys are used, 1 for the sender 1 for the receiver

• Transforms the data ready to compare to a database

• Is not very secure

• 's two keys are different and it is virtually impossible to get one key from the other

Asymmetric encryption ..

• Sends out new keys can be sent out each time there is a new message

• Negates the risk of sharing keys and interception risk is lowered

• Has a public and private key

• Interception and duplication of the key can happen
