Add PDFsharp 6.2.0 encryption samples (V1–V5, including missing top-level
/Lengthon V4)Adds PDF samples generated with PDFsharp 6.2.0 covering the standard security handler's
/V//Rcombinations (V1/R2 through V5/R6, RC4 40–128-bit and AES-128/256).Two files (
sample-V4-R2-RC4-128.pdf,sample-V4-R4-AES-128.pdf) omit the top-level/Lengthentry, since PDFsharp 6.2.0–6.2.3 don't write it for V4/V5 crypt-filter encryption. These are the files that exposed openwall/john#6033, wherepdf2john.pydefaulted to 40-bit instead of reading the crypt filter's/Length. Useful for regression testing against that class of file.All passwords: user
user123, ownerowner123.README.md included with the full breakdown.
