JAVA SHA1 加密 对应 c# SHA1 加密

java:

　　public static String SHA1(String decript) {
        try {
            MessageDigest digest = MessageDigest.getInstance("SHA-1");
            digest.update(decript.getBytes("UTF-8"));
            byte[] messageDigest = digest.digest();
            StringBuilder hexString = new StringBuilder();
            for (byte message : messageDigest) {
                String shaHex = Integer.toHexString(message & 0xFF);
                if (shaHex.length() < 2)
                    hexString.append(0);

                hexString.append(shaHex);
            }
            return hexString.toString().toLowerCase();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "";
    }
