Decrypting refers to the process of converting encrypted data back into its original, readable form. Decryption is only possible when you have the correct decryption key, which is the reverse process of encryption.
What Does It Mean?
When data is encrypted, it is scrambled into an unreadable format to protect it. Decrypting it means you reverse that process, making the data readable again. However, without the decryption key, the data remains scrambled and unreadable.
Steps in the Decryption Process:
- Receive Encrypted Data: The data is received in an encrypted form (ciphertext).
- Use Decryption Key: The authorized user applies a decryption key to reverse the encryption.
- Get Plaintext: After decryption, the data is restored to its original, readable form (plaintext).
Why Is It Important?
- Data Accessibility: Decryption allows authorized users to access the original information stored in encrypted form.
- Data Integrity: It ensures that only those with the correct key can access the data, thus maintaining privacy and security.
