Protocol. At the top, there is a search bar with the text \"Search Wikipedia\" and a magnifying glass icon. The time displayed is 23:57, and the battery level is at 80%. Below the search bar, there is a flowchart illustrating the Signal Protocol, with labels such as \"Private key,\" \"Public key,\" \"DH,\" \"Key In KDF,\" \"Key Out,\" \"Receiving chain key,\" and \"Sending chain key.\" The flowchart uses arrows to show the process of encryption and decryption. The title of the article is \"Signal Protocol,\" and it is described as a \"Non-federated cryptographic protocol.\" The article mentions that it is about the encryption protocol and provides a link to the Signal (messaging app) and the Signal Foundation. The text at the bottom of the article states that the Signal Protocol is a non-federated cryptographic protocol that provides end-to-end encryption for voice and instant messaging conversations. The bottom of the screen shows navigation options such as \"Save,\" \"Language,\" \"Find in article,\" \"Theme,\" and \"Contents.\"\n\n Ovis2-8B\n\n🌱 Energy used: 0.272 Wh", "blurhash": "UC8E6$kCWAoL~qWBjsj[%MWBj[oLIUjZa|f7", "width": 966, "height": 2147 } ], "tag": [ { "type": "Hashtag", "href": "https://mastodon.bsd.cafe/tags/rcs", "name": "#rcs" }, { "type": "Hashtag", "href": "https://mastodon.bsd.cafe/tags/protocol", "name": "#protocol" }, { "type": "Hashtag", "href": "https://mastodon.bsd.cafe/tags/messaging", "name": "#messaging" }, { "type": "Hashtag", "href": "https://mastodon.bsd.cafe/tags/text", "name": "#text" }, { "type": "Hashtag", "href": "https://mastodon.bsd.cafe/tags/media", "name": "#media" }, { "type": "Hashtag", "href": "https://mastodon.bsd.cafe/tags/rich", "name": "#rich" }, { "type": "Hashtag", "href": "https://mastodon.bsd.cafe/tags/year", "name": "#year" }, { "type": "Hashtag", "href": "https://mastodon.bsd.cafe/tags/twothousandseven", "name": "#twothousandseven" }, { "type": "Hashtag", "href": "https://mastodon.bsd.cafe/tags/signal", "name": "#signal" }, { "type": "Hashtag", "href": "https://mastodon.bsd.cafe/tags/encryption", "name": "#encryption" } ], "replies": { "id": "https://mastodon.bsd.cafe/users/Dendrobatus_Azureus/statuses/114588895702558585/replies", "type": "Collection", "first": { "type": "CollectionPage", "next": "https://mastodon.bsd.cafe/users/Dendrobatus_Azureus/statuses/114588895702558585/replies?only_other_accounts=true&page=true", "partOf": "https://mastodon.bsd.cafe/users/Dendrobatus_Azureus/statuses/114588895702558585/replies", "items": [] } }, "likes": { "id": "https://mastodon.bsd.cafe/users/Dendrobatus_Azureus/statuses/114588895702558585/likes", "type": "Collection", "totalItems": 9 }, "shares": { "id": "https://mastodon.bsd.cafe/users/Dendrobatus_Azureus/statuses/114588895702558585/shares", "type": "Collection", "totalItems": 4 } } ] } }
