OpenSSL is a software library for applications that provide secure communications over computer networks against eavesdropping, and identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites. OpenSSL contains an open-source implementation of the SSL and TLS protocols.
Stunnel is used to provide secure encrypted connections for clients or servers that do not speak TLS or SSL natively. [4] It runs on a variety of operating systems, [5] including most Unix-like operating systems and Windows. Stunnel relies on the OpenSSL library to implement the underlying TLS or SSL protocol.
Several versions of the TLS protocol exist. SSL 2.0 is a deprecated [27] protocol version with significant weaknesses. SSL 3.0 (1996) and TLS 1.0 (1999) are successors with two weaknesses in CBC-padding that were explained in 2001 by Serge Vaudenay. [28]
OpenSSH (also known as OpenBSD Secure Shell [a]) is a suite of secure networking utilities based on the Secure Shell (SSH) protocol, which provides a secure channel over an unsecured network in a client–server architecture.
Azure Linux is being developed by the Linux Systems Group at Microsoft for its edge network services and as part of its cloud infrastructure. [5] The company uses it as the base Linux for containers in the Azure Stack HCI implementation of Azure Kubernetes Service. [4]
Dropbear is a software package written by Matt Johnston that provides a Secure Shell-compatible server and client. [2] It is designed as a replacement for standard OpenSSH for environments with low memory and processor resources, such as embedded systems.
The software in this package is not included in Ubuntu by default, as Ubuntu maintainers wish to include only completely free software in out-of-the-box installations. Included packages may be closed-source , encumbered by software patents , or otherwise restricted.
The OpenSSL PRNG was removed (and replaced with ChaCha20-based implementation of arc4random). Preprocessor macros that have been deemed unnecessary or insecure or had already been deprecated in OpenSSL for a long time (e.g. des_old.h). Older unneeded files for assembly language, C, and Perl (e.g. EGD). MD2, SEED functionality. SSL 3.0, SHA-0 ...
