WebJun 20, 2024 · Elliptic curve cryptography brings short keys sizes and faster evaluation of operations when compared to algorithms based on RSA. Elliptic curves were standardized during the early 2000s, and have recently gained popularity as they are a more efficient way for securing communications. WebAug 11, 2024 · For example, the NIST P-256 curve is supported by Web Crypto API, which should be constant-time and "secure" (in the sense "we don't know effective, practical attacks against it"). Meanwhile the more modern Curve25519 is considered to be safer and less prone to implementation errors than P-256, but it isn't supported by Web Crypto API yet.
