Module: Mongo::Socket::OcspCache Private

Defined in:
build/ruby-driver-v2.19/lib/mongo/socket/ocsp_cache.rb

Overview

This module is part of a private API. You should avoid using this module if possible, as it may be removed or be changed in the future.

This module caches OCSP responses for their indicated validity time.

The key is the CertificateId used for the OCSP request. The value is the SingleResponse.

Since:

  • 2.0.0

Class Method Details

.clear ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Note:

Use Mongo.clear_ocsp_cache from applications instead of invoking this method directly.

Clears the driver’s OCSP response cache.

Since:

  • 2.0.0

.get(cert_id) ⇒ OpenSSL::OCSP::SingleResponse

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Retrieves a cached SingleResponse for the specified CertificateId.

This method may return expired responses if they are revoked. Such responses were valid when they were first received.

This method may also return responses that are valid but that may expire by the time caller uses them. The caller should not perform update time checks on the returned response.

Returns:

  • (OpenSSL::OCSP::SingleResponse) —

    The previously retrieved response.

Since:

  • 2.0.0
