fhevm is a full-stack blockchain framework designed to integrate Fully Homomorphic Encryption into smart contracts. It provides a platform for developing confidential smart contracts that can process encrypted data and execute private on-chain computations without decrypting the underlying information. The framework utilizes a coprocessor system to offload resource-intensive encrypted operations to an asynchronous service, improving blockchain performance and scalability. It incorporates a secure key management service based on multi-party computation and a zero-knowledge proof verifier to en

CryptoSwift is a cryptography library implemented entirely in the Swift programming language. It provides a collection of standard cryptographic algorithms for encryption, decryption, and hashing without relying on native C libraries or system frameworks. The library supports symmetric and asymmetric encryption, including RSA key generation and signature management. It features authenticated encryption schemes and the ability to generate cryptographic digests for data integrity verification. The toolset covers message authentication codes, secure key derivation from passwords, and data paddi

SEAL is a homomorphic encryption library and C++ cryptography framework that enables mathematical operations on encrypted data without requiring decryption. It provides a toolset for performing additions and multiplications on encrypted integers and complex numbers to support privacy-preserving computation. The framework implements the BFV and CKKS schemes, allowing for both modular arithmetic on encrypted integers and approximate arithmetic on fixed-precision floating-point numbers. It includes specialized wrappers to integrate these cryptographic workflows into .NET environments and support
