Looks for a gem dependency file at path and activates the gems in the file if found. If the file is not found an ArgumentError is raised.

If path is not given the RUBYGEMS_GEMDEPS environment variable is used, but if no file is found no exception is raised.

If ‘-’ is given for path RubyGems searches up from the current working directory for gem dependency files (gem.deps.rb, Gemfile, Isolate) and activates the gems in the first one found.

You can run this automatically when rubygems starts. To enable, set the RUBYGEMS_GEMDEPS environment variable to either the path of your gem dependencies file or “-” to auto-discover in parent directories.

NOTE: Enabling automatic discovery on multiuser systems can lead to execution of arbitrary code when used from directories outside your control.

The home directory for the user.

Path for gems in the user’s home directory

Verifies whether the signature is valid given the message digest input. It does so by validating sig using the public key of this DSA instance.

Parameters

• digest is a message digest of the original input data to be signed

• sig is a DSA signature value

Example

dsa = OpenSSL::PKey::DSA.new(2048)
doc = "Sign me"
digest = OpenSSL::Digest.digest('SHA1', doc)
sig = dsa.syssign(digest)
puts dsa.sysverify(digest, sig) # => true

The list of cipher suites configured for this context.

Sets the list of available cipher suites for this context. Note in a server context some ciphers require the appropriate certificates. For example, an RSA cipher suite can only be chosen when an RSA certificate is available.

Sends “close notify” to the peer and tries to shut down the SSL connection gracefully.

If sync_close is set to true, the underlying IO is also closed.

The X509 certificate for this socket endpoint.

Returns the cipher suite actually used in the current session, or nil if no session has been established.

See IO#close for details.
