javascript - RSA Encryption (softAP setup of microcontroller) in C# -

-

i'm trying configure wifi credentials particle photon (wifi microcontroller cloud support).

there existing methods java / ios / android / javascript.

however, need in c# (for desktop , xamarin multiplatform app).

i succesfully managed connect device, retreive it's id, retreive public key , nearby wifi access points (using webrequests , deserialized json objects)

however, stuck rsa encryption of wifi password need pass through.

i'm trying use rsacryptoserviceprovider encrypt need pass xml string , key in different (base64?) format. there seems kind of splicing needs happen.

this retreived public key (in hex):

30819f300d06092a864886f70d010101050003818d00308189028181009885dc94e34a23a2942bb9eb6721c4233e9edcc9a967f587cea527e1d447f48319ca6c4178dff739c0ab079e02467dd4d3ad3214416f0983c3967ea71378d7d93a885f1575d71d009990bffc0882fc721f4dc98a0d80b4ccf12e51066d69055e9a3c95e247beb9dc16176a083de7fa93c23449a3870d599da9d507964f7fc4b90203010001000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

this function in github softap-js:

softap.prototype.publickey = function publickey(cb) {  is(cb); var sock = this.__sendcommand('public-key', response.bind(this)); function response(err, dat) {      if(err) { return cb(err); }     if(!dat) { return cb(new error('no data received')); }     if(dat.r !== 0) {         return cb(new error('received non-zero response code'));     }     var buff = new buffer(dat.b, 'hex');     this.__publickey = new rsa(buff.slice(22), 'pkcs1-public-der', {         encryptionscheme: 'pkcs1'     })     cb(null, this.__publickey.exportkey('pkcs8-public')); }; return sock;

};

which appears handle public key. guess need somehow convert .net appreciate or hint since i'm not familiar @ encryption.

i try , create radar chart using chart.js has various colours each scaleline, or coloured between scalelines. wondering if possible? from: to: i have working graph, though there doesn't seem method change individual scale lines. kind regards leigh you can extend radar chart type this, so chart.types.radar.extend({ name: "radaralt", initialize: function (data) { chart.types.radar.prototype.initialize.apply(this, arguments); var originalscaledraw = this.scale.draw; var ctx = this.chart.ctx; this.scale.draw = function () { var linewidth = this.linewidth; // bypasses line drawing in originalscaledraw this.linewidth = linewidth; originalscaledraw.apply(this, arguments); ctx.linewidth = this.linewidth; var scale = this; // draw chart.helpers.each(scale.ylabels, function (label, index) { // color of ...

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
