OpenSSL::PKey::EC

< OpenSSL::PKey::PKey include OpenSSL::Marshal 20 instance methods 3 class methods

OpenSSL::PKey::EC provides access to Elliptic Curve Digital Signature Algorithm (ECDSA) and Elliptic Curve Diffie-Hellman (ECDH).

Key exchange

Example

ec1 = OpenSSL::PKey::EC.generate("prime256v1")
ec2 = OpenSSL::PKey::EC.generate("prime256v1")
# ec1 and ec2 have own private key respectively
shared_key1 = ec1.dh_compute_key(ec2.public_key)
shared_key2 = ec2.dh_compute_key(ec1.public_key)

p shared_key1 == shared_key2 #=> true
