This class represents a response received by the SMTP server. Instances of this class are created by the SMTP class; they should not be directly created by the user. For more information on SMTP responses, view Section 4.2 of RFC 5321
Specifies a Specification object that should be activated. Also contains a dependency that was used to introduce this activation.
File::Constants provides file-related constants. All possible file constants are listed in the documentation but they may not all be present on your platform.
If the underlying platform doesn’t define a constant the corresponding Ruby constant is not defined.
Your platform documentations (e.g. man open(2)) may describe more detailed information.
An error caused by conflicts in version
An OpenSSL::OCSP::Request contains the certificate information for determining if a certificate has been revoked or not. A Request can be created for a certificate or from a DER-encoded request created elsewhere.
The X509 certificate store holds trusted CA certificates used to verify peer certificates.
The easiest way to create a useful certificate store is:
cert_store = OpenSSL::X509::Store.new cert_store.set_default_paths
This will use your system’s built-in certificates.
If your system does not have a default set of certificates you can obtain a set from Mozilla here: curl.haxx.se/docs/caextract.html (Note that this set does not have an HTTPS download option so you may wish to use the firefox-db2pem.sh script to extract the certificates from a local install to avoid man-in-the-middle attacks.)
After downloading or generating a cacert.pem from the above link you can create a certificate store from the pem file like this:
cert_store = OpenSSL::X509::Store.new cert_store.add_file 'cacert.pem'
The certificate store can be used with an SSLSocket like this:
ssl_context = OpenSSL::SSL::SSLContext.new ssl_context.cert_store = cert_store tcp_socket = TCPSocket.open 'example.com', 443 ssl_socket = OpenSSL::SSL::SSLSocket.new tcp_socket, ssl_context
