2018-08-13Fix fallback logic for encryption (fixes #229)Jay Berkenbilt
2018-08-12Fix memory access errorJay Berkenbilt
A previous fix introduced a potentially memory overrun under certain rare conditions. The test suite now once again passes with address sanitizer.
2018-08-05Return correct method for string encryption (fixes #227)Jay Berkenbilt
2018-06-23Bug fix: honor encryption key length with R=3 (fixes #212)Jay Berkenbilt
2018-01-14Allow raw encryption key to be specifiedJay Berkenbilt
Add options to enable the raw encryption key to be directly shown or specified. Thanks to Didier Stevens <didier.stevens@gmail.com> for the idea and contribution of one implementation of this idea.
2017-08-27Pad keys to avoid memory errors (fixes #147)Jay Berkenbilt
2017-08-22Push QPDF member variables into a nested classJay Berkenbilt
Pushing member variables into a nested class enables addition of new member variables without breaking binary compatibility.
2017-08-12Pad encryption parameters that are too short (fixes #96)Jay Berkenbilt
2015-02-21Avoid buffer overrun copying digestJay Berkenbilt
Converting a password to an encryption key is supposed to copy up to a certain number of bytes from a digest. Make sure never to copy more than the size of the digest.
2013-11-29Include <algorithm> for std::min, std::maxJay Berkenbilt
2013-10-18Security: replace operator[] with atJay Berkenbilt
For std::string and std::vector, replace operator[] with at. This was done using an automated process. See README.hardening for details.
2013-06-15Handle more broken filesJay Berkenbilt
Space rather than newline after xref, missing /ID in trailer for encrypted file. This enables qpdf to handle some files that xpdf can handle. Adobe reader can't necessarily handle them.
2013-06-14Promote QPDF::ObjGen to top-level object QPDFObjGenJay Berkenbilt
2013-03-04Fix unused local variable warningsJay Berkenbilt
2013-03-04Remove all old-style casts from C++ codeJay Berkenbilt
2012-12-31Support for encryption with /V=5 and /R=5 and /R=6Jay Berkenbilt
Read and write support is implemented for /V=5 with /R=5 as well as /R=6. /R=5 is the deprecated encryption method used by Acrobat IX. /R=6 is the encryption method used by PDF 2.0 from ISO 32000-2.
2012-12-31Support files with only attachments encryptedJay Berkenbilt
Test cases added in a future commit since they depend on /R=6 support.
2012-12-31Fix infinite loop trimming passwords with ( in themJay Berkenbilt
2012-12-31Update AES classes to work with 256-bit keysJay Berkenbilt
2012-12-31Add V5 parameters to EncryptionDataJay Berkenbilt
2012-12-31change EncryptionDataJay Berkenbilt
2012-07-16Add command line option to copy encryption from other fileJay Berkenbilt
Add --copy-encryption and --encryption-file-password options to qpdf. Also strengthen test suite for copying encryption. The strengthened test suite would have caught the failure to preserve AES and the failure to update the file version, which was invalidating the encrypted data.
2012-06-20ABI change: fix use of off_t, size_t, and integer typesJay Berkenbilt
Significantly improve the code's use of off_t for file offsets, size_t for memory sizes, and integer types in cases where there has to be compatibility with external interfaces. Rework sections of the code that would have prevented qpdf from working on files larger than 2 (or maybe 4) GB in size.

Fix libtests test suites to pass on Windows, mostly by dealing with ascii vs. binary and NL vs. CRNL change ($td->NORMALIZE_NEWLINES). Convert some test suites to use fread instead of read.
