--- Comment #4 from Julien Nabet <[email protected]> --- Code pointer (for devs): https://opengrok.libreoffice.org/xref/core/sdext/source/pdfimport/pdfparse/pdfentries.cxx?r=f24d38de#1210 pdf specs: https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008.pdf " (Optional) A code specifying the algorithm to be used in encrypting and decrypting the document: 0 An algorithm that is undocumented. This value shall not be used. 1 "Algorithm 1: Encryption of data using the RC4 or AES algorithms" in 7.6.2, "General Encryption Algorithm," with an encryption key length of 40 bits; see below. 2 (PDF 1.4) "Algorithm 1: Encryption of data using the RC4 or AES algorithms" in 7.6.2, "General Encryption Algorithm," but permitting encryption key lengths greater than 40 bits. 3 (PDF 1.4) An unpublished algorithm that permits encryption key lengths ranging from 40 to 128 bits. This value shall not appear in a conforming PDF file. 4 (PDF 1.5) The security handler defines the use of encryption and decryption in the document, using the rules specified by the CF, StmF, and StrF entries. The default value if this entry is omitted shall be 0, but when present should be a value of 1 or greater. " -- You are receiving this mail because: You are the assignee for the bug.
