PDFBlackbox (.NET) 5.2.121

Add support for PDF security to C# or VB.NET (.NET Framework) applications PDFBlackbox.NET is a comprehensive collection of managed components that help you encrypt, sign and compress PDF documents from your .NET Framework applications. Both symmetric and certificate-based (X.509) encryption and signing is supported.PDFBlackbox (.NET) is a tool that adds support for PDF security to C# or VB.NET applications.
PDFBlackbox supports full range of PDF security operations, including:
- PDF standard password-based data encryption using MD5 + RC4/40 or RC4/128 algorithms;
- PDF certificate-based public key data encryption using RSA algorithm and PKCS#7 format;
- certificate-based data signing using SHA1 with RSA algorithms and PKCS#1 or PKCS#7 format;
- ZLib compression;
- stream-based processing, which lets you handle huge amounts of data without significant memory requirements;
- support for PDF format versions 1.3 to 1.6
PDFBlackbox components are a clean-room implementation of PDF format specification, which dont use any third-party libraries for core functionality.
