?Java 通用 SHA1 and? MD5 算法,改SHA1只需把
???????? hash = MessageDigest.getInstance("MD5").digest(string.getBytes("UTF-8"));
改成:
???????? hash = MessageDigest.getInstance("SHA1").digest(string.getBytes("UTF-8"));
然后再改改catch里的语句就OK
?
public static String md5(String string) { byte[] hash; try { hash = MessageDigest.getInstance("MD5").digest(string.getBytes("UTF-8")); } catch (NoSuchAlgorithmException e) { throw new RuntimeException("Huh, MD5 should be supported?", e); } catch (UnsupportedEncodingException e) { throw new RuntimeException("Huh, UTF-8 should be supported?", e); } StringBuilder hex = new StringBuilder(hash.length * 2); for (byte b : hash) { if ((b & 0xFF) < 0x10) hex.append("0"); hex.append(Integer.toHexString(b & 0xFF)); } return hex.toString();}
