hash - Custom C++ ASP .NET Membership Login -

does know how can hash user's password using salt key provided asp .net membership?

i'm developing c++ linux application , have access sql server.

thanks,

here encoding algorithm used asp.net membership written in c#.

it uses system.security, might want @ mono if want run on lunix.

note: i'm not familiar mono.

private string encodepassword(string pass, int passwordformat, string salt) { if (passwordformat == 0) // membershippasswordformat.clear homecoming pass; byte[] bin = encoding.unicode.getbytes(pass); byte[] bsalt = convert.frombase64string(salt); byte[] bret = null; if (passwordformat == 1) { // membershippasswordformat.hashed hashalgorithm hm = gethashalgorithm(); if (hm keyedhashalgorithm) { keyedhashalgorithm kha = (keyedhashalgorithm)hm; if (kha.key.length == bsalt.length) { kha.key = bsalt; } else if (kha.key.length < bsalt.length) { byte[] bkey = new byte[kha.key.length]; buffer.blockcopy(bsalt, 0, bkey, 0, bkey.length); kha.key = bkey; } else { byte[] bkey = new byte[kha.key.length]; (int iter = 0; iter < bkey.length; ) { int len = math.min(bsalt.length, bkey.length - iter); buffer.blockcopy(bsalt, 0, bkey, iter, len); iter += len; } kha.key = bkey; } bret = kha.computehash(bin); } else { byte[] ball = new byte[bsalt.length + bin.length]; buffer.blockcopy(bsalt, 0, ball, 0, bsalt.length); buffer.blockcopy(bin, 0, ball, bsalt.length, bin.length); bret = hm.computehash(ball); } } else { byte[] ball = new byte[bsalt.length + bin.length]; buffer.blockcopy(bsalt, 0, ball, 0, bsalt.length); buffer.blockcopy(bin, 0, ball, bsalt.length, bin.length); bret = encryptpassword(ball, _legacypasswordcompatibilitymode); } homecoming convert.tobase64string(bret); } private string generatesalt() { byte[] buf = new byte[salt_size]; (new rngcryptoserviceprovider()).getbytes(buf); homecoming convert.tobase64string(buf); }
