This comes in useful for various cases, such as securing online communications, storing sensitive information, and verifying digital identities.<\/li>\n<li>There are\u00a0two main types of encryption:\n<ul>\n<li>\u00a0Symmetric: It uses the\u00a0same 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.<\/li>\n<li>Asymmetric: It uses a pair of keys:\u00a0one public and one private. The public key can be shared with anyone, but the private key must be kept secret.<\/li>\n<\/ul>\n<\/li>\n<li>The term encryption is generally used when referring to the privacy of stored data, while end-to-end encryption protects data as it\u2019s\u00a0transferred between a location \u2013 which is crucial wherever there\u2019s a rapid exchange of information.<\/li>\n<li>In an E2EE-enabled app, only the person on each end \u2013 the sender and receiver \u2013 can read any exchanged messages.<\/li>\n<li>This is because messages get encrypted on your device before being sent and only are decrypted when they reach your intended recipient.<\/li>\n<\/ul>\n<h2>Issues with End-to-end encryption<\/h2>\n<ul>\n<li>Some\u00a0potent malware can also \u2018snoop\u2019 on your messages by infiltrating your device via other means \u2013 an SMS and reading them before they are encrypted.<\/li>\n<li>The company that installs E2E encryption on its products can\u00a0install a backdoor or an exception that allows the company to surmount the encryption and access the messages.<\/li>\n<\/ul>\n<hr \/>\n<h3>Q1) What is the Chameleon Trojan?<\/h3>\n<p>It is a malware that has the ability to disable biometric authentication methods, including fingerprint and face unlock, to sneakily access sensitive information.<\/p>\n<p><strong>Source:<\/strong> <a href=\"https:\/\/www.thehindu.com\/sci-tech\/science\/end-to-end-encryption-messaging-apps-explained\/article67765395.ece\" target=\"_blank\" rel=\"nofollow noopener\">What is end-to-end encryption?
