Hola gracias por contestar. Te pongo el código:
<%@ page import="java.security.*"%>
<%
final int SHA1_DIGEST_LENGTH = 20;
java.text.SimpleDateFormat formador = new java.text.SimpleDateFormat("yyMMddHHmmss");
String Merchant_Name = "Simulador de Comercio";
String Merchant_Code = "999008881";
int Merchant_Terminal = 4;
String Merchant_Order = formador.format(new java.util.Date());
String Merchant_Password = "qwertyasdf0123456789";
String Merchant_Amount = "100";
String Merchant_Currency = "978";
String Merchant_TransactionType = "0";
String Merchant_MerchantURL = "http://www.sermepa.es";
byte bAmount[] = new byte[Merchant_Amount.length()];
byte bOrder[] = new byte[Merchant_Order.length()];
byte bCode[] = new byte[Merchant_Code.length()];
byte bCurrency[] = new byte[Merchant_Currency.length()];
byte bTransactionType[] = new byte[Merchant_TransactionType.length()];
byte bMerchantURL[] = new byte[Merchant_MerchantURL.length()];
byte bPassword[] = new byte[Merchant_Password.length()];
bAmount = Merchant_Amount.getBytes();
bOrder = Merchant_Order.getBytes();
bCode = Merchant_Code.getBytes();
bCurrency = Merchant_Currency.getBytes();
bTransactionType = Merchant_TransactionType.getBytes();
bMerchantURL = Merchant_MerchantURL.getBytes();
bPassword = Merchant_Password.getBytes();
MessageDigest sha = MessageDigest.getInstance("SHA-1");
sha.update(bAmount);
sha.update(bOrder);
sha.update(bCode);
sha.update(bCurrency);
sha.update(bTransactionType);
sha.update(bMerchantURL);
byte[] hash = sha.digest(bPassword);
String Merchant_Signature = new String();
int h = 0;
String s = new String();
for(int i = 0; i < SHA1_DIGEST_LENGTH; i++)
{
h = (int) hash[i]; // Convertir de byte a int
if(h < 0) h += 256; // Si son valores negativos, pueden haber problemas de conversi¢n.
s = Integer.toHexString(h); // Devuelve el valor hexadecimal como un String
if (s.length() < 2) Merchant_Signature = Merchant_Signature.concat("0"); // A¤ade un 0 si es necesario
Merchant_Signature = Merchant_Signature.concat(s); // A¤ade la conversi¢n a la cadena ya existente
}
Merchant_Signature = Merchant_Signature.toUpperCase(); // Convierte la cadena generada a Mayusculas.
