Quick Answer: When Can Data Be Encrypted?

How can data be encrypted?

Data, or plaintext, is encrypted with an encryption algorithm and an encryption key.

The process results in ciphertext, which only can be viewed in its original form if it is decrypted with the correct key.

Can encrypted data be hacked?

Encrypted data can be hacked or decrypted with enough time and computing resources, revealing the original content. Hackers prefer to steal encryption keys or intercept data before encryption or after decryption. The most common way to hack encrypted data is to add an encryption layer using an attacker’s key.

Why we need to encrypt the data?

Encryption enhances the security of a message or file by scrambling the content. To encrypt a message, you need the right key, and you need the right key to decrypt it as well.It is the most effective way to hide communication via encoded information where the sender and the recipient hold the key to decipher data.
