enkripsi data

What is data encryption and why is it important?

• Data encryption is the same as data compression.

• Data encryption makes data completely inaccessible to users.

• Data encryption is the process of converting data into a coded format to prevent unauthorized access, and it is important for protecting sensitive information and ensuring privacy.

• Data encryption is only necessary for financial transactions.

How does encryption help in securing sensitive information?

• Encryption makes data more accessible to everyone.

• Encryption slows down data processing without any security benefits.

• Encryption is only useful for protecting physical documents.

• Encryption secures sensitive information by converting it into a coded format that is unreadable without a decryption key.

What are the common types of encryption methods used today?

• HMAC

• AES, RSA, DES, Blowfish, ECC

• SHA-1

• MD5

Explain the difference between symmetric and asymmetric encryption.

• Symmetric encryption uses one key for both processes, while asymmetric encryption uses a pair of keys.

• Asymmetric encryption is faster than symmetric encryption for all data sizes.

• Symmetric encryption is only used for digital signatures, while asymmetric is for data encryption.

• Symmetric encryption uses two keys, while asymmetric uses one key.

What role do encryption keys play in data security?

• Encryption keys are used to store passwords securely.

• Encryption keys protect data by enabling secure encryption and decryption, ensuring only authorized access.

• Encryption keys are primarily for data compression.

• Encryption keys are only necessary for data backups.
