keystore - Genarate ECPublicKey in java -

-

hi new java ecc encryption.so got ecc public key data array java card.the size 49 byte length.so need genarate eccpublic key.so have created public key.but gives java.security.spec.invalidkeyspecexception: encoded key spec not recognised error.this code can me how generate eccpublickey using data array.thanks

byte[] pub = new byte[] {             /*(public data) 49 length byte array             */                };              system.out.println("length :" + pub.length);             x509encodedkeyspec ks = new x509encodedkeyspec(pub);              keyfactory kf;             try {                 kf = keyfactory.getinstance("ecdh");              } catch (nosuchalgorithmexception e) {                 e.printstacktrace();                 return;             }              ecpublickey remotepublickey;              try {                 remotepublickey = (ecpublickey) kf.generatepublic(ks);             } catch (invalidkeyspecexception e) {                 e.printstacktrace();                 return;             } catch (classcastexception e) {                 e.printstacktrace();                 return;             }             system.out.println(remotepublickey);          } catch (exception e) {             e.printstacktrace();         }

the reason code not working keyspec can't use in ecc.so found how use ecpublickeyspec in ecc.in here has explanation.https://bitcointalk.org/index.php?topic=2899.0;wap2 thanks.

python - TypeError: can only concatenate tuple (not "float") to tuple -

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
