Place the CETAN server binary and configuration files under a dedicated directory on your Linux host. Adjust permissions and service configuration according to your environment.

Safe Library

The Safe Library provides a C++ API for working with encrypted .safe files. Developers can embed Safe directly into their applications to securely store and retrieve secrets such as passwords, API keys, and private keys.

Safe Library package

Contains the C++ headers, static library (libctn-safe.a), shared library (libctn-safe.so). Use it to create Safe files, add entries, retrieve values, and manage encrypted secrets programmatically.

After downloading, extract cetan-safe-2.0.0.tar.gz to a preferred location. Include the include/ directory in your compiler's header search path and link against libctn-safe.a or libctn-safe.so depending on your build configuration.

Safe tool

Safe tool provide a CLI for managing encrypted .safe files used to store secrets such as passwords, API keys, and private keys.

Safe tool package

Contains the safe CLI binary and supporting files. Use it to create Safe files, add entries, retrieve values, generate salts and passwords, and compute HMACs.

After downloading, extract cetan-safe-tool-2.0.0.tar.gz to a preferred location and ensure the safe binary is executable. You can then use it to manage secrets referenced by CETAN.

SLog Library

The SLog Library provides a lightweight, high performance C++ logging framework used throughout CETAN. It offers structured logging, log levels, timestamped entries, and pluggable output backends suitable for embedded systems, servers, and modular applications.

SLog Library package

Contains the C++ headers, static library (libctn-slog.a), shared library (libctn-slog.so). Use it to integrate structured logging into your applications, emit diagnostic messages, and build consistent logging pipelines across CETAN modules.

After downloading, extract cetan-slog-2.5.0.tar.gz to a preferred location. Include the include/ directory in your compiler's header search path and link against libctn-slog.a when building applications that use the SLog logging framework.

CETAN REST API SDK

The CETAN REST API SDK provides headers and libraries for building C++ REST applications that run on the CETAN Web Application Server.

REST API SDK

Includes the CETAN REST headers (include/), libraries (lib/), and example projects such as cetan-rest-101.

Language: C++23 File: cetan-rest-2.5.0.tar.gz Target: Linux server deployment

After extracting the SDK, copy the include and lib directories into your project and configure your build system to link against libctn-rest.so.

JSON Library

The CETAN JSON Library provides a lightweight, high‑performance C++ JSON parser and generator. It is used throughout CETAN for building REST responses, parsing structured data, and constructing JSON objects in a memory‑efficient manner suitable for servers, embedded systems, and modular applications.

JSON Library package

Contains the C++ headers, static library (libctn-json.a), and shared library (libctn-json.so). Use it to integrate fast JSON serialization and parsing into your CETAN applications or any standalone C++ project requiring efficient JSON handling.

After downloading, extract cetan-json-2.0.0.tar.gz to a preferred location. Include the include/ directory in your compiler's header search path and link against libctn-json.a or libctn-json.so when building applications that use the CETAN JSON framework.

CETAN Docker Image

The CETAN Docker Image provides a fully containerized version of the CETAN Web Application Server. It includes the CETAN runtime, required libraries, and a hardened entrypoint designed for secure, non-root execution. Use this package to deploy CETAN quickly on Linux servers, cloud environments, or container orchestration platforms.

CETAN Docker Image package

Contains the prebuilt Docker image (cetan:latest) packaged as a compressed archive. Load it using docker load and run CETAN with mounted configuration, security files, logs, and application directories.

File: cetan-docker-latest-2.5.0.tar.gz
