CAS has developed the CAS Digital Signature Solution which gives individuals and companies the ability to assign and validate digital signatures on electronic documents.
For the insertion and validation of signatures the solution works to authenticate the integrity of content through encryption and decryption using public and private key concepts.

For complete analysis of digital signatures generated by the solution or those externally, CAS Digital Signature Solution performs analysis of the certificates chain and certificate revocation list, allowing users to display the issued certificates by ICP-Brazil, accompanied by various relevant fields defined by that institution in the appropriate format.

The implementation is easy and offers the opportunity for users to assign and validate digital signatures of electronic documents.

The CAS Digital Signature Library is a pioneering solution that enables the deployment of the benefits of a digital signature directly in applications or systems that manage electronic documents.

The CAS Digital Signature Library is a library that manages the development of authentication tasks of applications, incorporating legal validity to documents on the basis of standards for issuing digital certificates and rules of ICP-Brazil.

Since its implementation every document generated by the application is automatically assigned a digital signature. The digital signature associated with the document is the basis for two endorsements: the author of the document and the integrity of the content.

Developed by CAS the CAS Digital Signature Portal – PAD – simplifies the process of allocation of digital signatures and sharing electronic documents, coordinating access by multiple users and acting positively in establishing and maintaining a flow of documents.

Offering complete management and efficient routines in various business the solution helps to significantly reduce the time spent on transactions between legal entities and individuals and contributes to eliminating the use of paper.

The CAS Digital Signature Portal – PAD – is ideal for transactions that require multiple signatures and efficiency in document sharing, integrating processes and to connect people. The solution offers different types of access to meet different needs of each member of the process.
