UnverifiedThe Web Crypto API provides standard cryptographic primitives such as AES-GCM, RSA-OAEP, and ECDH; operations are executed at the browser's underlying layer and do not expose keys to the JavaScript runtime.78% similarVerifiedAuthenticated encryption (such as AES-GCM mode) can detect whether ciphertext has been tampered with while ensuring confidentiality.78% similarUnverifiedHomomorphic encryption can perform computations directly on encrypted data without first decrypting it, and the results are also encrypted and can only be decrypted by those who hold the key.78% similar
