End-to-end (E2E) encryption protects information in a way that has transformed human rights organisations’, law-enforcement agencies’, and technology companies’ outlook on their ability to access and use information.
- Encryption is a way of protecting data from unauthorised access or tampering.
- It works by transforming the data into a secret code that only the intended recipient can decipher.
- This comes in useful for various cases, such as securing online communications, storing sensitive information, and verifying digital identities.
- There are two main types of encryption:
- Symmetric: It uses the same key to encrypt and decrypt the data. In symmetric encryption, the key used to encrypt some information is also the key required to decrypt it.
- Asymmetric: It uses a pair of keys: one public and one private. The public key can be shared with anyone, but the private key must be kept secret.
- The term encryption is generally used when referring to the privacy of stored data, while end-to-end encryption protects data as it’s transferred between a location – which is crucial wherever there’s a rapid exchange of information.
- In an E2EE-enabled app, only person on each end – the sender and receiver – can read any exchanged messages.
- This is because messages get encrypted on your device before being sent and only are decrypted when they reach your intended recipient.
Hence only statement 1 is correct.

Consider the following statements regarding the encryption:1. It prote...
1. Statement 1:
Encryption indeed protects data from unauthorized access by converting the original data into a coded form that can only be accessed by individuals with the correct decryption key. This ensures that sensitive information remains confidential and secure.
2. Statement 2:
Symmetric encryption actually uses the same key for both encryption and decryption of data, not a different key. This key is shared between the sender and the recipient to secure the communication and ensure that only authorized parties can access the encrypted data.
Therefore, in this case, only the first statement is correct. Symmetric encryption involves the use of a single key for both encryption and decryption processes.
