Which is the equivalent openssl commad to this c# signing code -


i have following code sign file:

using system; using system.collections.generic; using system.io; using system.linq; using system.security.cryptography.x509certificates; using system.security.cryptography.pkcs; using system.text; using system.threading.tasks; using disig.timestampclient; using system.xml.linq;  namespace clienttest {     class program     {         static void main(string[] args)         {              var certificate = getcertificate("mycert.pfx", "password");             var data = file.readallbytes("data.bin");             var signature = computesignature(data, certificate);             savepemsignature(signature, "file-signature.pem");         }          static void savepemsignature(byte[] signature, string filepath)         {             var base64 = convert.tobase64string(signature);             using (var writer = new streamwriter(filepath, false, encoding.default))             {                  writer.writeline("-----begin cms-----");                 var pos = 0;                 while (pos < base64.length)                 {                     var len = math.min(64, base64.length - pos);                     var line = base64.substring(pos, len);                     writer.writeline(line);                     pos += len;                 }                 writer.writeline("-----end cms-----");             }         }            static byte[] computesignature(byte[] data, x509certificate2 certificate)         {             if (data == null) throw new argumentnullexception("data");             if (certificate == null)                 throw new argumentnullexception("certificate");             contentinfo content = new contentinfo(data);             signedcms signedcms = new signedcms(content, true);             cmssigner signer = new cmssigner(subjectidentifiertype.subjectkeyidentifier, certificate);             signer.digestalgorithm = system.security.cryptography.oid.fromfriendlyname("sha256", system.security.cryptography.oidgroup.hashalgorithm);             signedcms.computesignature(signer);             return signedcms.encode();         }          static x509certificate2 getcertificate(string filepath, string password)         {             x509certificate2collection collection = new x509certificate2collection();             collection.import(filepath, password, x509keystorageflags.persistkeyset);             var cert = collection.cast<x509certificate2>()                 .firstordefault(x => x.privatekey != null && x.extensions.oftype<x509keyusageextension>().firstordefault(c => (c.keyusages & x509keyusageflags.digitalsignature) == x509keyusageflags.digitalsignature) != null);             return cert;         }     } }

which equivalent openssl command?

i tried following, had not luck, pem files different:

openssl cms -in data.bin -sign -signer mycert.pem -md sha256 -binary -noattr -outform pem -out file-signature.pem

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...

Add new key value to json node in java -

i have json file : { "id":1, "name":"abc", "addressdetails": { "city":"newyork" } } i wanted add 1 more key-value ("pincode" : "414141") node 'addressdetails'. i tried using : objectmapper mapper = new objectmapper(); jsonnode root = mapper.readtree(new file("d://test.json")); objectnode node = mapper.createobjectnode(); node.with("addressdetails").put("pincode", "414141"); but it's not getting added, there way can ? you can try you should modify file path objectmapper mapper = new objectmapper(); objectnode nodes = mapper.readvalue(new file("d:\\test.txt"), objectnode.class); nodes.with("addressdetails").put("pincode", "414141"); mapper.writer().writevalue(new file("d:\\test.txt"), nodes);
