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

Deduce Ruby’s –program-prefix and –program-suffix from its install name

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.

Example

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

> not critical

Returns a status string for the response.

Adds a validation status (0 for good, 1 for revoked, 2 for unknown) to this response for certificate_id. reason describes the reason for the revocation, if any.

The revocation_time, this_update and next_update are times for the certificate’s revocation time, the time of this status and the next update time for a new status, respectively.

extensions may be an Array of OpenSSL::X509::Extension that will be added to this response or nil.

See the OpenSSL documentation for EC_KEY_set_private_key()

Both public_key? and private_key? may return false at the same time unlike other PKey classes.

See the OpenSSL documentation for EC_KEY_generate_key()

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.
