The line number in the source code where this AST’s text began.
The column number in the source code where this AST’s text began.
Returns the original source code as an array of lines.

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.
Sets p, q, g to the DH instance.
Sets pub_key and priv_key for the DH instance. priv_key may be nil.
Serializes a private or public key to a DER-encoding.
See to_pem for details.
This method is kept for compatibility. This should only be used when the traditional, non-standard OpenSSL format is required.
Consider using public_to_der or private_to_der instead.
Sets p, q, g to the DSA instance.
Sets pub_key and priv_key for the DSA instance. priv_key may be nil.
Obtains a list of all predefined curves by the OpenSSL. Curve names are returned as sn.
See the OpenSSL documentation for EC_get_builtin_curves().
Generates a new random private and public key.

ec = OpenSSL::PKey::EC.new("prime256v1") p ec.private_key # => nil ec.generate_key! p ec.private_key # => #<OpenSSL::BN XXXXXX>
Serializes a private or public key to a DER-encoding.
See to_pem for details.
This method is kept for compatibility. This should only be used when the SEC 1/RFC 5915 ECPrivateKey format is required.

Generates a new random private and public key.

ec = OpenSSL::PKey::EC.new("prime256v1") p ec.private_key # => nil ec.generate_key! p ec.private_key # => #<OpenSSL::BN XXXXXX>
Encrypt string with the private key. padding defaults to PKCS1_PADDING, which is known to be insecure but is kept for backwards compatibility. The encrypted string output can be decrypted using public_decrypt.
Deprecated in version 3.0. Consider using PKey::PKey#sign_raw and PKey::PKey#verify_raw, and PKey::PKey#verify_recover instead.
Decrypt string, which has been encrypted with the private key, with the public key. padding defaults to PKCS1_PADDING which is known to be insecure but is kept for backwards compatibility.
