QCryptographicHash露

PyQt5.QtCore.QCryptographicHash

Description露

The QCryptographicHash class provides a way to generate cryptographic hashes.

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.

Enums露

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.

Methods露

__init__(Algorithm)

TODO

addData(bytes)

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

addData(Union[QByteArray, bytes, bytearray])

This function overloads addData().

addData(QIODevice) → bool

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

@staticmethod
hash(Union[QByteArray, bytes, bytearray], Algorithm) → QByteArray

Returns the hash of data using method.

@staticmethod
hashLength(Algorithm) → int

Returns the size of the output of the selected hash method in bytes.

reset()

Resets the object.

result() → QByteArray

Returns the final hash value.
