Though they certainly can try to bypass it, it could take several years if you’re using 256-bit AES encryption. … Unless you’re a person of extreme interest, it’s unlikely any hacker is going to spend time even trying.

How do I find encrypted data?

How does encryption keep data safe?

Encryption is the process of taking plain text, like a text message or email, and scrambling it into an unreadable format — called “cipher text.” This helps protect the confidentiality of digital data either stored on computer systems or transmitted through a network like the internet.

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. Symmetric-key ciphers use the same secret key for encrypting and decrypting a message or file.
