That error message is from main/svx/source/items/svxerr.src:
139 String ERRCODE_SVX_READ_FILTER_PPOINT & ERRCODE_RES_MASK
140 {
141 Text [ en-US ] = "The loading of password-encrypted Microsoft
PowerPoint presentations is not supported." ;
142 };
which is used in main/sd/source/filter/sdpptwrp.cxx method
SdPPTFilter::Import():
107 if ( pStorage->IsStream( String(
RTL_CONSTASCII_USTRINGPARAM("EncryptedSummary") ) ) )
108 mrMedium.SetError(
ERRCODE_SVX_READ_FILTER_PPOINT, ::rtl::OUString( RTL_CONSTASCII_USTRINGPARAM(
OSL_LOG_PREFIX ) ) );
On https://learn.microsoft.com/en-us/openspecs/office_file_formats/ms-
ppt/8faaf589-abed-4d79-a758-529ce59dfcfd we learn:
---snip---
2.1.6 Encrypted Summary Information Stream
02/14/2019
An optional stream whose name MUST be "EncryptedSummary". This stream
exists only in an encrypted document.
The contents of this stream are specified in [MS-OFFCRYPTO] section 2.3.5.4.
---snip---
I've used the MS-OFFCRYPTO specification before to add support for OOXML
decryption, but that's in a different section and uses different data
structures and algorithms, and cannot be reused for this.
