Essential features to make your job easier

You have the style

While security is important, the first glance is unforgettable. That's why we added a visual signature in addition to strong cryptography.

The authenticity of the visual signature example is protected with cryptographic algorithms.

Immutable signature connections

After you sign the document, immutable cryptographic links are established between your identity, each file you sign, the signing date, and your signing key.

These connections can be validated independently of our service, as all the necessary information is available in ASIC signature containers that you can download at any time.

Legally binding

The Agrello electronic signatures comply with the advanced electronic signature standard eIDAS, which establishes an immutable link between the user and the signature.
