WebE ncryption with EC keys is based on the Elliptic Curve Diffie-Hellman (ECDH) key agreement protocol. Signing with EC keys is based on the Elliptic Curve DSA (ECDSA) algorithm. The encryption with EC OpenPGP keys is considered to be much more secure compared to the current RSA and Elgamal (DH/DSS) keys. Supported EC curves WebMar 1, 2024 · For privatekey, OpenSSL (and lots of things built on it like nodejs PHP python) can use either the SEC1 ASN.1 format (also copied in rfc5915) or PKCS8, usually in PEM only (libcrypto supports both PEM and DER, but libssl makes using PEM easier); most other implementations I know of use PKCS8/rfc5208 and/or PKCS12/rfc7292, the former often …

WebMar 18, 2024 · When we generate an EC public/private key pair, we pick a number x and compute the elliptic curve point x G, which is G (the well-known "generator point") added to itself x times. The public key is the point x G; because it is a point, we need to state whether we're expressing that point in compressed or uncompressed format.
