Detailed Description

TheQSslCipher class represents an SSL cryptographic cipher.

QSslCipher stores information about one cryptographic cipher. It is most commonly used withQSslSocket, either for configuring which ciphers the socket can use, or for displaying the socket's ciphers to the user.

Member Function Documentation

QSslCipher::QSslCipher()

Constructs an emptyQSslCipher object.

QSslCipher::QSslCipher(constQString & name,QSsl::SslProtocol protocol)

Constructs aQSslCipher object for the cipher determined byname andprotocol. The constructor accepts only supported ciphers (i.e., thename andprotocol must identify a cipher in the list of ciphers returned byQSslSocket::supportedCiphers()).

You can callisNull() after construction to check ifname andprotocol correctly identified a supported cipher.

QSslCipher::QSslCipher(constQSslCipher & other)

Constructs an identical copy of theother cipher.

QSslCipher::~QSslCipher()

Destroys theQSslCipher object.

QString QSslCipher::authenticationMethod() const

Returns the cipher's authentication method as aQString.

QString QSslCipher::encryptionMethod() const

Returns the cipher's encryption method as aQString.

bool QSslCipher::isNull() const

Returns true if this is a null cipher; otherwise returns false.

QString QSslCipher::keyExchangeMethod() const

Returns the cipher's key exchange method as aQString.

QString QSslCipher::name() const

Returns the name of the cipher, or an emptyQString if this is a null cipher.

See alsoisNull().

QSsl::SslProtocol QSslCipher::protocol() const

Returns the cipher's protocol type, orQSsl::UnknownProtocol ifQSslCipher is unable to determine the protocol (protocolString() may contain more information).

See alsoprotocolString().

QString QSslCipher::protocolString() const

Returns the cipher's protocol as aQString.

See alsoprotocol().

int QSslCipher::supportedBits() const

Returns the number of bits supported by the cipher.

See alsousedBits().

int QSslCipher::usedBits() const

Returns the number of bits used by the cipher.

See alsosupportedBits().

bool QSslCipher::operator!=(constQSslCipher & other) const

Returns true if this cipher is not the same asother; otherwise, false is returned.

QSslCipher & QSslCipher::operator=(constQSslCipher & other)

Copies the contents ofother into this cipher, making the two ciphers identical.

bool QSslCipher::operator==(constQSslCipher & other) const

Returns true if this cipher is the same asother; otherwise, false is returned.
