Defines a method method which delegates to accessor (i.e. it calls the method of the same name in accessor). If new_name is provided, it is used as the name for the delegate method. Returns the name of the method defined.
Returns whether or not the struct of type type
contains member
. If it does not, or the struct type can’t be found, then false is returned. You may optionally specify additional headers
in which to look for the struct (in addition to the common header files).
If found, a macro is passed as a preprocessor constant to the compiler using the type name and the member name, in uppercase, prepended with HAVE_
.
For example, if have_struct_member('struct foo', 'bar')
returned true, then the HAVE_STRUCT_FOO_BAR
preprocessor macro would be passed to the compiler.
HAVE_ST_BAR
is also defined for backward compatibility.
Returns a list of paths matching glob
from the latest gems that can be used by a gem to pick up features from other gems. For example:
Gem.find_latest_files('rdoc/discover').each do |path| load path end
if check_load_path
is true (the default), then find_latest_files
also searches $LOAD_PATH for files as well as gems.
Unlike find_files
, find_latest_files
will return only files from the latest version of a gem.
The file name and line number of the caller of the caller of this method.
depth
is how many layers up the call stack it should go.
e.g.,
def a; Gem.location_of_caller
; end a #=> [“x.rb”, 2] # (it’ll vary depending on file name and line number)
def b; c; end def c; Gem.location_of_caller(2)
; end b #=> [“x.rb”, 6] # (it’ll vary depending on file name and line number)
Returns the latest release-version specification for the gem name
.
Returns the latest release version of RubyGems.
Returns the version of the latest release-version of gem name
Returns the value of Gem.source_date_epoch_string
, as a Time
object.
This is used throughout RubyGems for enabling reproducible builds.
Path to specification files of default gems.
Deduce Ruby’s –program-prefix and –program-suffix from its install name
Default options for gem commands for Ruby packagers.
The options here should be structured as an array of string “gem” command names as keys and a string of the default options as values.
Example:
def self.operating_system_defaults
{ 'install' => '--no-rdoc --no-ri --env-shebang', 'update' => '--no-rdoc --no-ri --env-shebang' }
end
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.
dh = OpenSSL::PKey::DH.new(2048) public_key = dh.public_key #contains no private/public key yet public_key.generate_key! puts public_key.private? # => true
See the OpenSSL
documentation for EC_KEY_get0_private_key()
See the OpenSSL
documentation for EC_KEY_set_private_key()
Generates a new random private and public key.
See also the OpenSSL
documentation for EC_KEY_generate_key()
ec = OpenSSL::PKey::EC.new("prime256v1") p ec.private_key # => nil ec.generate_key! p ec.private_key # => #<OpenSSL::BN XXXXXX>
Returns whether this EC
instance has a private key. The private key (BN
) can be retrieved with EC#private_key
.
Generates a new random private and public key.
See also the OpenSSL
documentation for EC_KEY_generate_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. The encrypted string output can be decrypted using public_decrypt
.
Decrypt string, which has been encrypted with the public key, with the private key. padding defaults to PKCS1_PADDING.
Adds a certificate to the context. pkey must be a corresponding private key with certificate.
Multiple certificates with different public key type can be added by repeated calls of this method, and OpenSSL
will choose the most appropriate certificate during the handshake.
cert=
, key=
, and extra_chain_cert=
are old accessor methods for setting certificate and internally call this method.
A certificate. An instance of OpenSSL::X509::Certificate
.
The private key for certificate. An instance of OpenSSL::PKey::PKey
.
Optional. An array of OpenSSL::X509::Certificate
. When sending a certificate chain, the certificates specified by this are sent following certificate, in the order in the array.
rsa_cert = OpenSSL::X509::Certificate.new(...) rsa_pkey = OpenSSL::PKey.read(...) ca_intermediate_cert = OpenSSL::X509::Certificate.new(...) ctx.add_certificate(rsa_cert, rsa_pkey, [ca_intermediate_cert]) ecdsa_cert = ... ecdsa_pkey = ... another_ca_cert = ... ctx.add_certificate(ecdsa_cert, ecdsa_pkey, [another_ca_cert])
OpenSSL
before the version 1.0.2 could handle only one extra chain across all key types. Calling this method discards the chain set previously.
Returns the last Finished message sent
Creates a new X509::Extension
with passed values. See also x509v3_config(5).
