References comphelper::Hash::calculateHash(), and msfilter::MSCodec97::m_hCipher.
◆ GetEncryptionData()
|
overridevirtual |
Retrieves the encryption data.
- Returns
- The sequence contains the necessary data to initialize the codec.
Reimplemented from msfilter::MSCodec97.
Definition at line 489 of file mscodec.cxx.
References comphelper::SequenceAsHashMap::getAsConstNamedValueList(), msfilter::MSCodec97::GetEncryptionData(), and m_aStd97Key.
◆ InitCipher()
|
overridevirtual |
Rekeys the codec using the specified counter.
After reading a specific amount of data the cipher algorithm needs to be rekeyed using a counter that counts the data blocks.
The block size is for example 512 Bytes for Word files and 1024 Bytes for Excel files.
@precond The codec must be initialized with InitKey() before this function can be used.
- Parameters
-
nCounter Block counter used to rekey the cipher.

◆ InitKey()
|
overridevirtual |
Initializes the algorithm with the specified password and document ID.
- Parameters
-
pPassData Wide character array containing the password. Must be zero terminated, which results in a maximum length of 15 characters. pDocId Unique document identifier read from or written to the file.
