New in version 5.12.
- static PySide6.QtNetwork.QPasswordDigestor.deriveKeyPbkdf1(algorithm, password, salt, iterations, dkLen)¶
Returns a hash computed using the PBKDF1-algorithm as defined in RFC 8018, section 5.1.
The function takes the
salt, and then hashes it repeatedly for
iterations iterations using the specified hash
algorithm. If the resulting hash is longer than
dkLen then it is truncated before it is returned.
This function only supports SHA-1 and MD5! The max output size is 160 bits (20 bytes) when using SHA-1, or 128 bits (16 bytes) when using MD5. Specifying a value for
dkLen which is greater than this results in a warning and an empty
QByteArray is returned. To programmatically check this limit you can use
hashLength . Furthermore: the
salt must always be 8 bytes long!
This function is provided for use with legacy applications and all new applications are recommended to use
- static PySide6.QtNetwork.QPasswordDigestor.deriveKeyPbkdf2(algorithm, password, salt, iterations, dkLen)¶
Derive a key using the PBKDF2-algorithm as defined in RFC 8018, section 5.2.
This function takes the
salt, and then applies HMAC-X, where the X is
algorithm, repeatedly. It internally concatenates intermediate results to the final output until at least
dkLen amount of bytes have been computed and it will execute HMAC-X
iterations times each time a concatenation is required. The total number of times it will execute HMAC-X depends on
algorithm and can be calculated as
iterations * ceil(dkLen / QCryptographicHash::hashLength(algorithm)).
