Events¶

`ocsp_extension`: `event`	This event is raised when an OCSP extension is encountered in an OCSP response.
`ocsp_request`: `event`	Event that is raised when encountering an OCSP request, e.g.
`ocsp_request_certificate`: `event`	Event that is raised when encountering an OCSP request for a certificate, e.g.
`ocsp_response_bytes`: `event`	This event is raised when encountering an OCSP response that contains response information.
`ocsp_response_certificate`: `event`	This event is raised for each SingleResponse contained in an OCSP response.
`ocsp_response_status`: `event`	This event is raised when encountering an OCSP reply, e.g.

Detailed Interface¶

Events¶

ocsp_extension¶

Type: event (f: fa_file, ext: X509::Extension, global_resp: bool)

This event is raised when an OCSP extension is encountered in an OCSP response. See RFC 6960 for more details on OCSP.

F: The file.
Ext: The parsed extension (same format as X.509 extensions).
Global_resp: T if extension encountered in the global response (in ResponseData), F when encountered in a SingleResponse.

ocsp_request¶

Type: event (f: fa_file, version: count)

Event that is raised when encountering an OCSP request, e.g. in an HTTP connection. See RFC 6960 for more details.

This event is raised exactly once for each OCSP Request.

F: The file.
Req: version: the version of the OCSP request. Typically 0 (Version 1).

ocsp_request_certificate¶

Type: event (f: fa_file, hashAlgorithm: string, issuerNameHash: string, issuerKeyHash: string, serialNumber: string)

Event that is raised when encountering an OCSP request for a certificate, e.g. in an HTTP connection. See RFC 6960 for more details.

Note that a single OCSP request can contain requests for several certificates. Thus this event can fire several times for one OCSP request, each time requesting information for a different (or in theory even the same) certificate.

F: The file.
HashAlgorithm: The hash algorithm used for the issuerKeyHash.
IssuerKeyHash: Hash of the issuers public key.
SerialNumber: Serial number of the certificate for which the status is requested.

ocsp_response_bytes¶

Type: event (f: fa_file, status: string, version: count, responderId: string, producedAt: time, signatureAlgorithm: string, certs: x509_opaque_vector)

This event is raised when encountering an OCSP response that contains response information. An OCSP reply can be encountered, for example, in an HTTP connection or a TLS extension. See RFC 6960 for more details on OCSP.

F: The file.
Status: The status of the OCSP response (e.g. succesful, malformedRequest, tryLater).
Version: Version of the OCSP response (typically - for version 1).
ResponderId: The id of the OCSP responder; either a public key hash or a distinguished name.
ProducedAt: Time at which the reply was produced.
SignatureAlgorithm: Algorithm used for the OCSP signature.
Certs: Optional list of certificates that are sent with the OCSP response; these typically are needed to perform validation of the reply.

ocsp_response_certificate ¶

Type: event (f: fa_file, hashAlgorithm: string, issuerNameHash: string, issuerKeyHash: string, serialNumber: string, certStatus: string, revokeTime: time, revokeReason: string, thisUpdate: time, nextUpdate: time)

This event is raised for each SingleResponse contained in an OCSP response. See RFC 6960 for more details on OCSP.

F: The file.
HashAlgorithm: The hash algorithm used for issuerNameHash and issuerKeyHash.
IssuerNameHash: Hash of the issuer’s distinguished name.
IssuerKeyHash: Hash of the issuer’s public key.
SerialNumber: Serial number of the affected certificate.
CertStatus: Status of the certificate.
RevokeTime: Time the certificate was revoked, 0 if not revoked.
RevokeTeason: Reason certificate was revoked; empty string if not revoked or not specified.
ThisUpdate: Time this response was generated.
NextUpdate: Time next response will be ready; 0 if not supploed.

ocsp_response_status¶

Type: event (f: fa_file, status: string)

This event is raised when encountering an OCSP reply, e.g. in an HTTP connection or a TLS extension. See RFC 6960 for more details.

This event is raised exactly once for each OCSP reply.

F: The file.
Status: The status of the OCSP response (e.g. succesful, malformedRequest, tryLater).
