Detailed Description

QSslKey provides a simple API for managing keys.

QSslSocket QSslCertificate QSslCipher

__init__()

Constructs a null key.

See also

isNull()

__init__(device, algorithm[, format=QSsl.Pem[, type=QSsl.PrivateKey[, passPhrase=QByteArray()]]])

Parameters:

• device – QIODevice

• algorithm – KeyAlgorithm

• format – EncodingFormat

• type – KeyType

• passPhrase – QByteArray

Constructs a QSslKey by reading and decoding data from a device using a specified algorithm and encoding format. type specifies whether the key is public or private.

If the key is encrypted then passPhrase is used to decrypt it.

After construction, use isNull() to check if device provided a valid key.

__init__(handle[, type=QSsl.PrivateKey])

Parameters:

• handle – Qt::HANDLE

• type – KeyType

Constructs a QSslKey from a valid native key handle. type specifies whether the key is public or private.

QSslKey will take ownership for this key and you must not free the key using the native library.

__init__(encoded, algorithm[, format=QSsl.Pem[, type=QSsl.PrivateKey[, passPhrase=QByteArray()]]])

Parameters:

• encoded – QByteArray

• algorithm – KeyAlgorithm

• format – EncodingFormat

• type – KeyType

• passPhrase – QByteArray

Constructs a QSslKey by decoding the string in the byte array encoded using a specified algorithm and encoding format. type specifies whether the key is public or private.

If the key is encrypted then passPhrase is used to decrypt it.

After construction, use isNull() to check if encoded contained a valid key.

__init__(other)

Parameters:

other – QSslKey

Constructs an identical copy of other.

algorithm()

Return type:

KeyAlgorithm

Returns the key algorithm.

clear()

Clears the contents of this key, making it a null key.

See also

isNull()

handle()

Return type:

Qt::HANDLE

Returns a pointer to the native key handle, if there is one, else None.

You can use this handle together with the native API to access extended information about the key.

Warning

Use of this function has a high probability of being non-portable, and its return value may vary across platforms, and between minor Qt releases.

isNull()

Return type:

bool

Returns true if this is a null key; otherwise false.

See also

clear()

length()

Return type:

int

Returns the length of the key in bits, or -1 if the key is null.

__ne__(key)

Parameters:

key – QSslKey

Return type:

bool

Returns true if this key is not equal to key other; otherwise returns false.

__eq__(key)

Parameters:

key – QSslKey

Return type:

bool

Returns true if this key is equal to other; otherwise returns false.

swap(other)

Parameters:

other – QSslKey

Swaps this ssl key with other. This function is very fast and never fails.

toDer([passPhrase=QByteArray()])

Parameters:

passPhrase – QByteArray

Return type:

QByteArray

Returns the key in DER encoding.

The passPhrase argument should be omitted as DER cannot be encrypted. It will be removed in a future version of Qt.

toPem([passPhrase=QByteArray()])

Parameters:

passPhrase – QByteArray

Return type:

QByteArray

Returns the key in PEM encoding. The result is encrypted with passPhrase if the key is a private key and passPhrase is non-empty.

type()

Return type:

KeyType

Returns the type of the key (i.e., PublicKey or PrivateKey).
