PDFlib PLOP is a versatile tool for linearizing, optimizing, repairing, analyzing, encrypting and decrypting PDF documents.
PDFlib PLOP DS additionally offers the ability to apply digital signatures to PDF documents. PLOP DS applies digital signatures to PDF documents according to the latest standards and technologies.
Our latest version 5.1 is even more powerful and has been considerably improved:
Support for signing with a Hardware Security Module (HSM)
Time-stamping according to RFC 5816
Optimized file size and processing time for generating signatures
Support for indirect CRLs
Enhanced robustness of CRL retrieval
Improvements for multi-threaded signing
PAdES/CAdES signatures created by default
Custom build for attaching external cryptographic engine for hashing and signing
Proven major features of PLOP and PLOP DS include:
Signatures enabled for Long-Term Validation (LTV)
All certificates embedded for validation without any prior configuration
Time-stamped signatures and document-level time-stamps
PDF/A, PDF/UA, PDF/X and PDF/VT conformance
Software and hardware certificates, e.g. smartcards or USB tokens
PDFlib TET (Text and Image Extraction Toolkit) reliably extracts text, images, metadata, and other elements from PDF documents.
TET PDF IFilter extracts text and metadata from PDF documents and makes it available to search and retrieval software on Windows.
TET 5 provides many significant functional enhancements, such as:
Text retrieval: retrieving fill and stroke color of text, improved layout detection
Image retrieval: significantly enhanced merging of fragmented images, extracting of image masks and soft masks
Page processing: honor layers and clipping paths
TETML content: including fill and stroke color of glyphs, color space and ICC profile details
several new pCOS pseudo-objects
