## About Microsoft SEAL
Microsoft SEAL is an open-source, cross-platform library developed by Microsoft Research that enables computations directly on encrypted data through homomorphic encryption. This allows developers to perform operations on sensitive information without exposing it, ensuring data privacy and security. Key Features and Functionality: - Homomorphic Encryption Schemes: Supports the BFV scheme for exact computations on encrypted integers and the CKKS scheme for approximate computations on encrypted real or complex numbers. - Cross-Platform Compatibility: Written in standard C++ with no external dependencies, making it compatible with various operating systems, including Windows, macOS, Linux, and Android. - Compression Support: Offers data compression using the DEFLATE algorithm to reduce memory usage when serializing objects like encryption parameters and keys. - .NET Support: Provides a .NET Standard library for seamless integration into .NET applications. Primary Value and Problem Solved: Microsoft SEAL empowers developers to build applications that can process sensitive data while maintaining confidentiality. By enabling computations on encrypted data, it eliminates the need to decrypt information, thereby reducing the risk of data breaches and unauthorized access. This is particularly valuable in sectors like healthcare, finance, and cloud computing, where data privacy is paramount.
