MD5加密32位C#版JAVA 版

C#版 private static string GetMd5(string str) { MD5 md5 = new MD5CryptoServiceProvider(); byte[] bytes = System.Text.Encoding.UTF8.GetBytes(str); bytes = md5.ComputeHash(bytes); md5.Clear(); string ret = ""; for (int i = 0; i < bytes.Length; i++) { ret += Convert.ToString(bytes[i], 16).PadLeft(2, '0'); } return ret.PadLeft(32, '0'); }

JAVA版

private static String MD5(String sourceStr) { String result = ""; try { MessageDigest md = MessageDigest.getInstance("MD5"); md.update(sourceStr.getBytes()); byte b[] = md.digest(); int i; StringBuffer buf = new StringBuffer(""); for (int offset = 0; offset < b.length; offset++) { i = b[offset]; if (i < 0) i += 256; if (i < 16) buf.append("0"); buf.append(Integer.toHexString(i)); } result = buf.toString(); } catch (NoSuchAlgorithmException e) { System.out.println(e); } return result; }
