TLS or Transport Layer Security is an encryption protocol. It is designed such that communication through TLS remains secure and private. In this post, I will explain what TLS handshake is and how ...

When a TLS client and server first start communicating, they agree on a protocol version, select cryptographic algorithms, optionally authenticate each other, and use public-key encryption ...

This week I’m dealing with secure e-mail, and in particular the Transport Layer Security (TLS) protocol. The financial services company for which I’m consulting is setting up secure e-mail ...

TLS protocol is a handshake protocol. It means that servers that are TLS enabled will exchange greetings and negotiate communication before they send encrypted data.

The Transport Level Security (TLS) protocol is one of the few rock-steady spots in the rapidly changing computing industry, but that’s about to change as quantum computers threaten traditional ...

How can Post-Quantum Cryptography (PQC) be used for protecting the widely used TLS 1.3 protocol? Transport Layer Security (TLS) is perhaps the most well-known cryptographic protocol. It is used for ...

Protection against replay for ordinary TLS 1.3 1-RTT data is provided via the server's Random value, but 0-RTT data does not depend on the ServerHello and therefore has weaker guarantees. This is ...

After having tweaked Firefox to only use TLS version 1.2, one website can verify that the tweak worked and another can test it.

AWS recently announced that TLS 1.2 is going to become the minimum protocol level for API endpoints. The cloud provider will remove backward compatibility and support for versions 1.0 and 1.1 on ...
