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.
