Javasign

Javasign is a handy software written in Java that helps you create digital signatures and timestamps on documents. You can use it with a smart card or a token file in p12 format, making it super flexible for your needs!

How Does Javasign Work?

So, here’s the scoop: Javasign works great with ISO 7816-4 compliant smart cards. It uses some nifty encryption and decryption functions based on PKCS #15 compliant cards. This means your data is secure and reliable.

Two Ways to Operate

• Smart Card: This mode does digital signature and verification right on the card itself. You can set it up to use the cryptoki library provided by your card vendor or an internal Java driver that takes care of low-level APDU commands.


• P12 File: In this mode, Javasign uses an external file in standard p12 format to manage private keys and certificates. It's simple and straightforward!

Certificate Verification

The cool part? Javasign can verify the certificate linked to your document! It checks if it's been issued by a trusted Certificate Authority (CA). Plus, it ensures that the certificate is still valid by checking against the CRL (Certificate Revocation List). It does this by downloading it from the CA site using either HTTP or LDAP protocols.

Based on Italian Standards

You might be interested to know that Javasign follows the Italian CNS specification for identity cards (Carta Nazionale dei Servizi). This makes it reliable and trustworthy for official use.
