I'm a Android and iOS developer and I'm starting to develop a App to sign and encrypt electronic documents in PKCS#7/CMS format and I would like to know what product I need to buy to cover Android and iOS platform.

Other doubt is about CAdES format, in your website there isn't a example about how the library sign documents in CAdES format, today is possible to sign in this format?

With how often chilkatsoft is released a new version?

Starting in Chilkat v9.3.0, it is possible to create CAdES-BES and CAdES-EPES digital signatures via the MailMan, Mime, and Crypt2 objects. All three objects/classes now include the following new properties:

bool CadesEnabled;
string CadesSigPolicyId;
string CadesSigPolicyUri;
string CadesSigPolicyHash;  (base64 encoded representation of hash)

To create a CAdES-BES signature, simply set the CadesEnabled property = true.

For CAdES-EPES, set each of the other new properties. For example:

crypt.CadesSigPolicyId = “″;
crypt.CadesSigPolicyUri = “http://politicas.icpbrasil.gov.br/PA_AD_RB.der”;
crypt.CadesSigPolicyHash = “rySugyKaMhiMR8Y/o5yuU2A2bF0=”;

If you set these properties prior to calling any method that creates a signature, then a CAdES signature is created.

A single license covers all supported operating systems, programming languages, frameworks, architectures, etc. For example, a 1-Developer Chilkat Crypt license is valid for the Crypt functionality across all platforms.

New releases are not regularly scheduled, but happen on average once every 4-5 months.

The 1-Developer Bundle is for 1 software developer (programmer), but the 4-Developer Bundle is for up to 4 developers (programmers).

How can I generate the CadesSigPolicyHash?

You don't actually generate the hash. The hash is pre-existing. For example, you can see various policy documents with corresponding hashes here: http://www.iti.gov.br/legislacao/144-icp-brasil/repositorio/3974-artefatos-de-assinatura-digital

If the published hash is hex, and you need base4 for Chilkat, then it's just a matter of re-encoding (decode from hex, encode to base64). You could just as well compute the hash of the policy document itself, which should equal the published hash.

Ok, but it's not work. I'm using this sample in Node to create a .p7s (Detached Signature) file. http://www.example-code.com/nodejs/crypt_create_p7s_using_pfx.asp

I'm using this parameters:

crypt.CadesEnabled= true; crypt.CadesSigPolicyId = ""; crypt.CadesSigPolicyUri = "http://politicas.icpbrasil.gov.br/PA_AD_RB_v2_1.der"; var b = new Buffer("3259f8a99b35393afadfa681fc381cd1eb6925c68718a8e92f7a658f253d3ba5",'hex'); console.log(b.toString('base64')) crypt.CadesSigPolicyHash = b.toString('base64');

The file is generated as success but when it is submited to test on https://verificador.iti.gov.br/verificador.xhtml it's don't pass.
