Microsoft SEAL vs. Evervault

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.

Evervault is a developer-first platform that helps payment providers and merchants collect, process, and share sensitive cardholder data without ever exposing it in plaintext. Its modular building blocks are designed to solve payment security, PCI compliance, and data protection challenges with minimal engineering effort. The platform uses a dual-custody encryption model: Evervault stores the encryption keys, while customers store the encrypted data. This separation drastically reduces breach risk and improves performance.
