What is ECC elliptic curve encryption
ECC is an asymmetric algorithm based on the elliptic curve discrete logarithm problem, delivering RSA-equivalent security with shorter keys. This tool generates key pairs (P-256/P-384/P-521), performs ECDSA signing/verification, and ECIES hybrid encryption via ECDH + AES-256-GCM, all locally in your browser.
Note· Keep your private key secure and never share it. ECC encryption uses ECIES (ECDH + AES-256-GCM); the ciphertext is JSON containing the ephemeral public key, IV, and ciphertext.
