Digital Document Signing with GroupDocs.Signature API
Whether you’re building a simple “sign‑once” portal or an enterprise‑grade approval pipeline, the API gives you granular control over how signatures are created, displayed, and validated. You can add visible signatures (text, images, QR codes, barcodes) or invisible cryptographic signatures that guarantee document integrity without altering the visual layout. The same codebase works across .NET and Java, letting you reuse business logic across platforms.
