# Olvid, secure messaging for everyone **Category:** [Ordinateurs](https://deliberahoc.com/c/computers-ordinateurs/15) **Created:** 2023-12-03 16:27 UTC **Views:** 213 **Replies:** 1 **URL:** https://deliberahoc.com/t/olvid-secure-messaging-for-everyone/894 --- ## Post #1 by @Patrick [date=2023-12-03 timezone="Europe/Paris"] The French government has asked members of the government and ministerial cabinets to install the French application [Olvid](https://olvid.io/en/) on their phones and computers *"to replace other instant messengers in order to reinforce the security of exchanges "*, the offices of Prime Minister Elisabeth Borne reported on Wednesday November 29, 2023 [Olvid](https://www.olvid.io/technology/en/) is a **secure messaging application designed to offer maximum protection for user confidentiality**. Based on strong cryptographic technology, it claims to be the world's most secure messaging application. Here are some key features of the Olvid application: 1. **End-to-end encryption**: Olvid uses end-to-end encryption to ensure the confidentiality of your messages. This means that only you and your recipient can read your messages. Even Olvid can't read them. 2. **No phone number or email required**: Unlike other messaging applications, Olvid doesn't require you to provide your phone number or email address to sign up. This adds an extra layer of confidentiality. 3. **Strong authentication**: Olvid uses a technology called "Key Agreement Protocol" to guarantee the authenticity of participants in a conversation. This prevents man-in-the-middle attacks. 4. **Self-destructing messages**: Olvid lets you configure messages to self-destruct after a certain time, adding an extra layer of security. 5. **Open-source**: Olvid is an open-source application, which means its code can be examined by anyone to verify its security. ![olvid-logo|500x147](upload://e66bZRcUDPqqYlYOEOUGqOTLBJH.png) **Benefits of the Olvid application:** 1. **Enhanced security:** Olvid is the world's most secure instant messaging application, with features such as the elimination of centralized user directories and end-to-end message encryption. 2. **Anssi certification:** Since September 2020, Olvid has been the only instant messaging application certified by the French national agency for information systems security (Anssi), reinforcing its credibility in terms of cybersecurity. 3. **Metadata removal:** Olvid goes beyond simple message encryption by also securing metadata, contributing to a more comprehensive protection of user confidentiality. 4. **Multi-platform availability:** Olvid is available free of charge on Android, iPhone and PC, making it easy to use on a variety of devices. 5. **Secure contact addition procedure:** Contacts are added by scanning a QR code, a secure method for guaranteeing contact authenticity. **Disadvantages of the Olvid application:** 1. **Limited adoption:** Despite its advanced features, Olvid's use remains limited, raising questions about its reliability when scaled up. 2. **Paid options:** Although the application is free, paid options are available, which may restrict full access for some users. 3. **Need to replace existing messaging services:** The process of transitioning to Olvid involves abandoning the main consumer instant messaging applications (WhatsApp, Telegram, Signal), which may be restrictive for users accustomed to these platforms. 4. **The deadline** set by the government for Olvid deployment (December 8, 2023) may be restrictive for government departments, requiring a rapid and potentially complex transition. 5. **Dependence on a single application:** By strongly encouraging the use of Olvid, there is a risk of dependence on a single application, which could cause problems in the event of future vulnerabilities or service failure.
