Secure and compliant
Anvil uses digital certificates for identity verification when signing documents. The widely accepted standard that we implement is known as Public Key Infrastructure (PKI) which consists of creating two certificates together, a public and a private.
When a document is signed on the Anvil platform, the data is encrypted with our private key using the 2048 RSA. That private key is stored in a Hardware Securtiy Module (HSM) which is inaccessible to anyone, including Anvil developers. Only the application itself can make calls to the private key. This ensures that no one can ever get their hands on the private key and impersonate an Anvil signature.
Anvil signatures can be verified by opening signed documents in a PDF viewer supporting signature verification.
