This enum was introduced or modified in Qt 6.1.
Describes the different key algorithms supported by QSslKey .
| 常量 | 值 | 描述 |
|---|---|---|
QSsl::Rsa

|
The Elliptic Curve algorithm. |
QSsl::Dh
|
4
|
The Diffie-Hellman algorithm. |
QSsl::Opaque
|
0
|
A key that should be treated as a 'black box' by QSslKey . |
The opaque key facility allows applications to add support for facilities such as PKCS#11 that Qt does not currently offer natively.
Describes the two types of keys QSslKey 支持。
| 常量 | 值 | 描述 |
|---|---|---|
QSsl::PrivateKey
|
0
|
私钥。 |
QSsl::PublicKey
|
1
|
公钥。 |
Describes the options that can be used to control the details of SSL behaviour. These options are generally used to turn features off to work around buggy servers.
| 常量 | 值 | 描述 |
|---|---|---|
QSsl::SslOptionDisableEmptyFragments
|
0x01
|
Disables the insertion of empty fragments into the data when using block ciphers. When enabled, this prevents some attacks (such as the BEAST attack), however it is incompatible with some servers. |
QSsl::SslOptionDisableSessionTickets
|
0x02
|
Disables the SSL session ticket extension. This can cause slower connection setup, however some servers are not compatible with the extension. |
QSsl::SslOptionDisableCompression
|
0x04
|
Disables the SSL compression extension. When enabled, this allows the data being passed over SSL to be compressed, however some servers are not compatible with this extension. |
QSsl::SslOptionDisableServerNameIndication
|
0x08
|
Disables the SSL server name indication extension. When enabled, this tells the server the virtual host being accessed allowing it to respond with the correct certificate. |
QSsl::SslOptionDisableLegacyRenegotiation
|
0x10
|
Disables the older insecure mechanism for renegotiating the connection parameters. When enabled, this option can allow connections for legacy servers, but it introduces the possibility that an attacker could inject plaintext into the SSL session. |
QSsl::SslOptionDisableSessionSharing
|
0x20
|
Disables SSL session sharing via the session ID handshake attribute. |
QSsl::SslOptionDisableSessionPersistence
|
0x40
|
Disables storing the SSL session in ASN.1 format as returned by QSslConfiguration::sessionTicket (). Enabling this feature adds memory overhead of approximately 1K per used session ticket. |
QSsl::SslOptionDisableServerCipherPreference
|
0x80
|
Disables selecting the cipher chosen based on the servers preferences rather than the order ciphers were sent by the client. This option is only relevant to server sockets, and is only honored by the OpenSSL backend. |
By default, SslOptionDisableEmptyFragments is turned on since this causes problems with a large number of servers. SslOptionDisableLegacyRenegotiation is also turned on, since it introduces a security risk. SslOptionDisableCompression is turned on to prevent the attack publicised by CRIME. SslOptionDisableSessionPersistence is turned on to optimize memory usage. The other options are turned off.
注意： Availability of above options depends on the version of the SSL backend in use.
The SslOptions type is a typedef for QFlags <SslOption>. It stores an OR combination of SslOption values.
