Which encryption method transforms data into an unreadable format and requires a decryption key to revert it to its original form?
- Asymmetric Encryption
- Hashing
- Salting
- Symmetric Encryption
Symmetric encryption transforms data into an unreadable format using a single encryption key. This encrypted data can only be decrypted using the same key, ensuring confidentiality. Without the decryption key, it is virtually impossible to revert the data to its original form, enhancing security. This method is commonly used for securing data in databases.
