Şifrelenmiş Mesajlaşma Uygulamaları
Bu mesajlaşma uygulamaları hassas iletişimlerinizi güvence altına almak için harikadır.
Signal
!!! öneri
{ align=right }
**Signal**, Signal Messenger LLC tarafından geliştirilen bir mobil uygulamadır. Uygulama anlık mesajlaşmanın yanı sıra sesli ve görüntülü arama da sağlıyor.
Tüm iletişimler uçtan uca şifrelemeye sahiptir. Kişileriniz Signal PIN'iniz kullanılarak şifrelenir ve sunucunun bunlara erişimi yoktur. Profiller de şifrelenir ve yalnızca sohbet ettiğiniz kişilerle paylaşılır.

Signal özel grupları destekler. Sunucuda grup üyeliklerinizin, grup adlarınızın, grup fotoğraflarınızın veya grup özelliklerinizin kaydı yoktur. Gizli Gönderici etkinleştirildiğinde Signal, en aza indirgenmiş metadata'ya sahiptir. Gönderenin adresi mesajla birlikte şifrelenir ve sunucu tarafından yalnızca alıcı adresi görülebilir. Gizli Gönderici varsayılan olarak yalnızca kişileriniz için etkindir ancak spam alma riskini arttırmakla beraber tüm alıcılar için etkinleştirilebilir. Signal, kişisel tanımlayıcı olarak telefon numaranızı gerektirir.
Protokol 2016 yılında bağımsız olarak denetlenmiştir. Signal protokolünün özellikleri dokümantasyonunda bulunabilir.

SimpleX Chat
!!! öneri
{ align=right }
**SimpleX** Chat is an instant messenger that is decentralized and doesn't depend on any unique identifiers such as phone numbers or usernames. Users of SimpleX Chat can scan a QR code or click an invite link to participate in group conversations.

SimpleX Chat was audited by Trail of Bits in October 2022.
Currently SimpleX Chat only provides a client for Android and iOS. Basic group chatting functionality, direct messaging, editing of messages and markdown are supported. E2EE Audio and Video calls are also supported.
Your data can be exported, and imported onto another device, as there are no central servers where this is backed up.
Briar
!!! öneri
{ align=right }
**Briar** is an encrypted instant messenger that [connects](https://briarproject.org/how-it-works/) to other clients using the Tor Network. Briar can also connect via Wi-Fi or Bluetooth when in local proximity. Briar’s local mesh mode can be useful when internet availability is a problem.

- [:simple-flathub: Flathub](https://flathub.org/apps/details/org.briarproject.Briar)
To add a contact on Briar, you must both add each other first. You can either exchange briar:// links or scan a contact’s QR code if they are nearby.
The client software was independently audited, and the anonymous routing protocol uses the Tor network which has also been audited.
Briar has a fully published specification.
Briar supports perfect forward secrecy by using the Bramble Handshake and Transport protocol.
Additional Options
!!! warning
These messengers do not have Perfect [Forward Secrecy](https://en.wikipedia.org/wiki/Forward_secrecy) (PFS), and while they fulfill certain needs that our previous recommendations may not, we do not recommend them for long-term or sensitive communications. Any key compromise among message recipients would affect the confidentiality of **all** past communications.
Element
!!! öneri
{ align=right }
**Element** is the reference client for the [Matrix](https://matrix.org/docs/guides/introduction) protocol, an [open standard](https://matrix.org/docs/spec) for secure decentralized real-time communication.
Messages and files shared in private rooms (those which require an invite) are by default E2EE as are one to one voice and video calls.

Profile pictures, reactions, and nicknames are not encrypted.
Group voice and video calls are not E2EE, and use Jitsi, but this is expected to change with Native Group VoIP Signalling. Group calls have no authentication currently, meaning that non-room participants can also join the calls. We recommend that you do not use this feature for private meetings.
The Matrix protocol itself theoretically supports PFS, however this is not currently supported in Element due to it breaking some aspects of the user experience such as key backups and shared message history.
The protocol was independently audited in 2016. The specification for the Matrix protocol can be found in their documentation. The Olm cryptographic ratchet used by Matrix is an implementation of Signal’s Double Ratchet algorithm.
Session
!!! öneri
{ align=right }
**Session** is a decentralized messenger with a focus on private, secure, and anonymous communications. Session offers support for direct messages, group chats, and voice calls.
Session uses the decentralized [Oxen Service Node Network](https://oxen.io/) to store and route messages. Every encrypted message is routed through three nodes in the Oxen Service Node Network, making it virtually impossible for the nodes to compile meaningful information on those using the network.

Session allows for E2EE in one-on-one chats or closed groups which allow for up to 100 members. Open groups have no restriction on the number of members, but are open by design.
Session does not support PFS, which is when an encryption system automatically and frequently changes the keys it uses to encrypt and decrypt information, such that if the latest key is compromised it exposes a smaller portion of sensitive information.
Oxen requested an independent audit for Session in March of 2020. The audit concluded in April of 2021, “The overall security level of this application is good and makes it usable for privacy-concerned people.”
Session has a whitepaper describing the technicals of the app and protocol.

- Must have open-source clients.
- Must use E2EE for private messages by default.
- Must support E2EE for all messages.
- Must have been independently audited.
