## Detailed Description

The QOcspResponse class represents the revocation status of a server's certificate, received by the client-side socket during the TLS handshake. QSslSocket must be configured with OCSP stapling enabled.

See also QSslSocket, QSslSocket::ocspResponses(), certificateStatus(), revocationReason(), responder(), subject(), QOcspCertificateStatus, QOcspRevocationReason, QSslConfiguration::setOcspStaplingEnabled(), QSslConfiguration::ocspStaplingEnabled(), and QSslConfiguration::peerCertificate().

## Member Function Documentation

### QOcspResponse::QOcspResponse()

Creates a new response with status QOcspCertificateStatus::Unknown and revocation reason QOcspRevocationReason::None.

See also QOcspCertificateStatus.

### QOcspResponse::QOcspResponse(const QOcspResponse &other)

Copy-constructs a QOcspResponse instance.

### `[noexcept]` QOcspResponse::QOcspResponse(QOcspResponse &&other)

Move-constructs a QOcspResponse instance.

### `[noexcept]` QOcspResponse::~QOcspResponse()

Destroys the response.

### QOcspCertificateStatus QOcspResponse::certificateStatus() const

Returns the certificate status.

See also QOcspCertificateStatus.

### class QSslCertificate QOcspResponse::responder() const

This function returns a certificate used to sign OCSP response.

### QOcspRevocationReason QOcspResponse::revocationReason() const

Returns the reason for revocation.

### QSslCertificate QOcspResponse::subject() const

This function returns a certificate, for which this response was issued.

### `[noexcept]` void QOcspResponse::swap(QOcspResponse &other)

Swaps this response with other. This operation is very fast and never fails.

### `[noexcept]` QOcspResponse &QOcspResponse::operator=(QOcspResponse &&other)

Move-assigns other to this QOcspResponse instance.

### QOcspResponse &QOcspResponse::operator=(const QOcspResponse &other)

Copy-assigns other and returns a reference to this response.

### enum class QOcspCertificateStatus

Describes the Online Certificate Status

Constant | Value | Description
--- | --- | ---
`QOcspResponse::QOcspCertificateStatus::Good` | `0` | The certificate is not revoked, but this does not necessarily mean that the certificate was ever issued or that the time at which the response was produced is within the certificate's validity interval.
`QOcspResponse::QOcspCertificateStatus::Revoked` | `1` | This state indicates that the certificate has been revoked (either permanently or temporarily - on hold).
`QOcspResponse::QOcspCertificateStatus::Unknown` | `2` | This state indicates that the responder doesn't know about the certificate being requested.

See also QOcspRevocationReason.

### enum class QOcspRevocationReason

Describes the reason for revocation

This enumeration describes revocation reasons, defined in RFC 5280, section 5.3.1

Constant | Value
--- | ---
`QOcspResponse::QOcspRevocationReason::None` | `-1`
`QOcspResponse::QOcspRevocationReason::Unspecified` | `0`
`QOcspResponse::QOcspRevocationReason::KeyCompromise` | `1`
`QOcspResponse::QOcspRevocationReason::CACompromise` | `2`
`QOcspResponse::QOcspRevocationReason::AffiliationChanged` | `3`
`QOcspResponse::QOcspRevocationReason::Superseded` | `4`
`QOcspResponse::QOcspRevocationReason::CessationOfOperation` | `5`
`QOcspResponse::QOcspRevocationReason::CertificateHold` | `6`
`QOcspResponse::QOcspRevocationReason::RemoveFromCRL` | `7`

### bool operator!=(const QOcspResponse &lhs, const QOcspResponse &rhs)

Returns `true` if lhs and rhs are responses for different certificates, or signed by different responders, or have different revocation reasons, or different certificate statuses.

### bool operator==(const QOcspResponse &lhs, const QOcspResponse &rhs)

Returns `true` if lhs and rhs are the responses for the same certificate, signed by the same responder, have the same revocation reason and the same certificate status.
