Constructors

• .new(key : String)
• .new(io : IO)
• .new(size : Int32)

Class Method Summary

• .compute_shared_secret(private_key : OpenSSL::PKey::EC, peer_public_key : OpenSSL::PKey::EC) : Bytes

  OpenSSL 3.x ECDH using EVP_PKEY_derive Returns the raw ECDH shared secret (no KDF).

• .from_private_bytes(bytes : Bytes, curve : String = "P-256")

  Create EC key from raw private key bytes For P-256, expects 32 bytes; for P-384, expects 48 bytes, etc.

• .from_public_bytes(bytes : Bytes, curve : String = "P-256")

  Create public key from raw bytes (uncompressed format: 0x04 + x + y)

• .generate(size : Int32)
• .generate(type : String)
• .generate_by_curve_name(curve_name : String)

  Generate EC key by curve name (supports non-NIST curves like secp256k1)
