PySide6.QtCore.QCryptographicHash¶

class QCryptographicHash¶

The QCryptographicHash class provides a way to generate cryptographic hashes.

Details

QCryptographicHash can be used to generate cryptographic hashes of binary or text data.

Refer to the documentation of the Algorithm enum for a list of the supported algorithms.

class Algorithm¶

Note

In Qt versions before 5.9, when asked to generate a SHA3 hash sum, QCryptographicHash actually calculated Keccak. If you need compatibility with SHA-3 hashes produced by those versions of Qt, use the Keccak_ enumerators. Alternatively, if source compatibility is required, define the macro QT_SHA3_KECCAK_COMPAT.

__init__(method)¶

Parameters:: method – Algorithm

Constructs an object that can be used to create a cryptographic hash from data using method.

addData(data)¶

Parameters:: data – QByteArrayView

Adds the characters in bytes to the cryptographic hash.

Note

In Qt versions prior to 6.3, this function took QByteArray , not QByteArrayView .

addData(device)

Parameters:: device – QIODevice
Return type:: bool

Reads the data from the open QIODevice device until it ends and hashes it. Returns true if reading was successful.

addData(data)

Parameters:: data – str

Note

This function is deprecated.

Adds the first length chars of data to the cryptographic hash.

Use the QByteArrayView overload instead.

algorithm()¶

Return type:: Algorithm

Returns the algorithm used to generate the cryptographic hash.

static hash(data, method)¶

Parameters:

data – QByteArrayView
method – Algorithm

Return type:

QByteArray

Returns the hash of data using method.

Note

In Qt versions prior to 6.3, this function took QByteArray , not QByteArrayView .
