# Supporting Components

The **Supporting Components** category includes essential modules that provide foundational services and utilities for the MOSIP platform. Below are the modules under this category:

* [**Biometrics**](https://github.com/mosip/documentation/blob/1.2.0/docs/id-lifecycle-management/biometrics/README.md): Handles biometric data processing, including capture, storage, and matching of biometric identifiers such as fingerprints and facial images.
* [**Commons**](https://github.com/mosip/documentation/blob/1.2.0/docs/id-lifecycle-management/commons/README.md): Provides shared libraries and utilities used across various MOSIP modules, promoting code reuse and consistency.
* [**Keymanager**](https://github.com/mosip/documentation/blob/1.2.0/docs/id-lifecycle-management/keymanager/README.md): Manages cryptographic keys and certificates, ensuring secure communication and data protection within the MOSIP ecosystem.
* [**Packet Manager**](https://github.com/mosip/documentation/blob/1.2.0/docs/id-lifecycle-management/packet-manager/README.md): Packet Manager securely manages registration packets by handling storage, encryption, validation, and API-based access. It operates both as a service and a library within the MOSIP platform.
* [**Persistence**](https://github.com/mosip/documentation/blob/1.2.0/docs/id-lifecycle-management/persistence/README.md): Manages data storage and retrieval, providing a robust and scalable database layer for MOSIP applications.
* [**Quality Manager**](https://github.com/mosip/documentation/blob/1.2.0/docs/id-lifecycle-management/quality-manager/README.md): Oversees quality assurance processes, including testing and validation of MOSIP components to ensure reliability and performance.
* [**Datashare**](https://github.com/mosip/documentation/blob/1.2.0/docs/id-lifecycle-management/datashare/README.md): Enables secure data sharing and interoperability between different MOSIP modules and external systems.
* [**Keycloak**](https://github.com/mosip/documentation/blob/1.2.0/docs/id-lifecycle-management/keycloak/README.md): Integrates with Keycloak for identity and access management, providing single sign-on (SSO) and user federation capabilities.

Each module plays a vital role in ensuring the reliability, scalability, and maintainability of the overall MOSIP system.
