PySide6.QtNetwork.QSslCipher

class QSslCipher

The QSslCipher class represents an SSL cryptographic cipher.

Details

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

__init__()

Constructs an empty QSslCipher object.

__init__(other)
Parameters:

other – QSslCipher

Constructs an identical copy of the other cipher.

__init__(name)
Parameters:

name – str

Constructs a QSslCipher object for the cipher determined by name. The constructor accepts only supported ciphers (i.e., the name must identify a cipher in the list of ciphers returned by QSslSocket::supportedCiphers()).

You can call isNull() after construction to check if name correctly identified a supported cipher.

__init__(name, protocol)
Parameters:

Constructs a QSslCipher object for the cipher determined by name and protocol. The constructor accepts only supported ciphers (i.e., the name and protocol must identify a cipher in the list of ciphers returned by QSslSocket::supportedCiphers()).

You can call isNull() after construction to check if name and protocol correctly identified a supported cipher.

authenticationMethod()
Return type:

str

Returns the cipher’s authentication method as a QString.

encryptionMethod()
Return type:

str

Returns the cipher’s encryption method as a QString.

isNull()
Return type:

bool

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

keyExchangeMethod()
Return type:

str

Returns the cipher’s key exchange method as a QString.

name()
Return type:

str

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

isNull()

__ne__(other)
Parameters:

other – QSslCipher

Return type:

bool

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

__eq__(other)
Parameters:

other – QSslCipher

Return type:

bool

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

protocol()
Return type:

SslProtocol

Returns the cipher’s protocol type, or UnknownProtocol if QSslCipher is unable to determine the protocol ( protocolString() may contain more information).

protocolString()

protocolString()
Return type:

str

Returns the cipher’s protocol as a QString.

protocol()

supportedBits()
Return type:

int

Returns the number of bits supported by the cipher.

usedBits()

swap(other)
Parameters:

other – QSslCipher

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

usedBits()
Return type:

int

Returns the number of bits used by the cipher.
