nSoftware Secure PDF is an easy-to-use library for adding robust PDF security to your apps. It makes it easy for developers to sign, verify, encrypt, and decrypt PDFs without writing complex code. It is compliant with the latest PDF security features, such as Basic Adobe Signatures and the advanced PAdES signature levels.

The library is suitable for companies requiring document security and trust. It integrates with current PKI infrastructure, validates certificates, provides timestamps, CRL, OCSP, and EU Trusted Lists, and maintains the authenticity and validity of PDF documents in the future. It also supports local and remote signing, allowing it to be used for workflows where signing is done on a different system.

nSoftware Secure PDF isn't just about security. You can also create and fill in PDF forms, insert images and graphics, merge/split pages, and manage attachments—even create compliant ZUGFeRD/Factur-X e-invoices. For more basic needs, nSoftware also provides PDF Password, a free command-line-based tool to password-protect PDFs directly from your computer without connecting to the internet.
