-> Encryption is the process of transforming plain data in a way that makes it harder for an unauthorized person to make sense of it. The encrypted data is called ciphertext.

-> An encryption algorithm makes data unreadable to any person or system until the associated decryption algorithm is applied
– Encryption does not hide data; it makes it unreadable
– Encryption is not the same as compression

Types of Encryption

• File Encryption
• Windows Data Protection
• Hashing, used for signing and validating
• Symmetric and Asymmetric
