The TlsGetValue and TlsSetValue functions are then used to read and write a memory address to a thread-local variable identified by the TLS slot index. TlsSetValue only affects the variable for the current thread. The TlsFree function can be called to release the TLS slot index. There is a Win32 Thread Information Block for each thread.
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet. The protocol is widely used in applications such as email , instant messaging , and voice over IP , but its use in securing HTTPS remains the most publicly visible.
The publishing of TLS 1.3 and DTLS 1.3 obsoleted TLS 1.2 and DTLS 1.2. Note that there are known vulnerabilities in SSL 2.0 and SSL 3.0. In 2021, IETF published RFC 8996 also forbidding negotiation of TLS 1.0, TLS 1.1, and DTLS 1.0 due to known vulnerabilities. NIST SP 800-52 requires support of TLS 1.3 by January 2024.
Transport Layer Security, a cryptographic protocol for secure computer network communication; Thread level speculation, an optimisation on multiprocessor CPUs; Thread-local storage, a mechanism for allocating variables in computer science; Transparent LAN Service, a transparent data link connecting remote Ethernet networks
During the TLS handshake the server and the client establish session keys (symmetric keys, used for the duration of a given session), but the encryption and signature of the TLS handshake messages itself is done using asymmetric keys, which requires more computational power than the symmetric cryptography used for the encryption/decryption of ...

In 2021 Google funded the creation of mod_tls, a new TLS module for Apache HTTP Server using Rustls. [38] [39] The new module is intended to be a successor to the mod_ssl module that uses OpenSSL, as a more secure default. [38] [40] As of August 2024, mod_tls is available in the latest version of Apache but still marked as experimental. [41]
TLS 1.0 (RFC 2246), 1.1 (RFC 4346), 1.2 (RFC 5246), and 1.3 (RFC 8446). The Transport Layer Security (TLS) protocol from the IETF supersedes SSL v3.0 while remaining backward-compatible with SSL v3 implementations. SSL 3.0. The Secure Sockets Layer (SSL) protocol allows mutual authentication between a client and server and the establishment of ...
