Sign in your own hand right in the browser —drawing your signature, with no certificate or install— or with a certified digital signature from the Central Bank of Costa Rica (BCCR). The certified signature is bound to your identity and, under Law 8454, holds the same legal value as a handwritten signature. Both are logged and verifiable by third parties.
The signature is applied from your own computer with the ArcaSign signer and your BCCR digital signature card. The private key never leaves the card: the document is signed locally and only the already-signed PDF travels to the cloud. Before signing you can place a visible seal on the page, and the PAdES signature is embedded in the file, verifiable in any reader.
All your case files in one place. Upload PDF documents, organize them by folder or label, and access the full history of each file from any device.
Every signature is logged: who signed, when, and from which IP. And anyone can verify a document signed in ArcaSign to confirm it is authentic and has not been altered, with no account needed.
All documents are stored encrypted at rest with AES-256 and travel encrypted over TLS 1.3. The infrastructure runs behind Cloudflare, with DDoS protection and continuous monitoring.
In addition to the BCCR certificate, each signature receives a timestamp issued by an external, independent Time-Stamping Authority (TSA). This guarantees that the document existed at exactly that moment, even if the ArcaSign system ceased to exist.
