The Crypthing Initiative
Signthing Personal Edition
The Crypthing project aims to develop cryptographic software for business, government and personal use within the context of Brazilian Public-Key Infrastructure (see Portal ICP-Brasil) under GNU General Public License. We are planning to deliver to open source community software for authentication, confidentiality and digital signature with strict compliance to ITI specifications.
The Signthing Personal Edition is our first delivery. This is an application to sign documents for non-repudiation purposes using cryptographic keys associated with digital certificates issued by one of the ICP-Brasil Certificate Authorities. Despite this design goal, you may also sign documents with any x.509 certificate issued by any Certificate Authority.
Current Features:- Support to DER encoded x.509 certificates stored in smart-cards and removable medias;
- ICP-Brasil compliance certificate validation and on-line revocation check over HTTP;
- Document signing, co-signing and verification (of course);
- Support to attached and detached RFC 2630 CMS SignedData envelope;
- Internationalized user's interface (currently in English and Portuguese);
- Platform-independent design (Java), already tested under Linux 2.6.24 and MS Windows XP (but only with Sun JVM).
