Encodes this ASN1Data into a DER-encoded String value. The result is DER-encoded except for the possibility of indefinite length forms. Indefinite length forms are not allowed in strict DER, so strictly speaking the result of such an encoding would be a BER-encoding.
See ASN1Data#to_der for details.
See ASN1Data#to_der for details.
Generates a private and public key unless a private key already exists. If this DH instance was generated from public DH parameters (e.g. by encoding the result of DH#public_key), then this method needs to be called first in order to generate the per-session keys before performing the actual key exchange.
Deprecated in version 3.0. This method is incompatible with OpenSSL 3.0.0 or later.
See also OpenSSL::PKey.generate_key.
Example:
# DEPRECATED USAGE: This will not work on OpenSSL 3.0 or later dh0 = OpenSSL::PKey::DH.new(2048) dh = dh0.public_key # #public_key only copies the DH parameters (contrary to the name) dh.generate_key! puts dh.private? # => true puts dh0.pub_key == dh.pub_key #=> false # With OpenSSL::PKey.generate_key dh0 = OpenSSL::PKey::DH.new(2048) dh = OpenSSL::PKey.generate_key(dh0) puts dh0.pub_key == dh.pub_key #=> false
Serializes the DH parameters to a DER-encoding
Note that any existing per-session public/private keys will not get encoded, just the Diffie-Hellman parameters will be encoded.
See also public_to_der (X.509 SubjectPublicKeyInfo) and private_to_der (PKCS #8 PrivateKeyInfo or EncryptedPrivateKeyInfo) for serialization with the private or public key components.
