    • md5Digest

      public static byte[] md5Digest(byte[] bytes)
      Calculate the MD5 digest of the given bytes.
      参数:
      bytes - the bytes to calculate the digest over
      返回:
      the digest

    • md5Digest

      public static byte[] md5Digest(InputStream inputStream) throws IOException

      public static String md5DigestAsHex(byte[] bytes)
      Return a hexadecimal string representation of the MD5 digest of the given bytes.
      参数:
      bytes - the bytes to calculate the digest over
      返回:
      a hexadecimal digest string

      参数:
      bytes - the bytes to calculate the digest over
      builder - the string builder to append the digest to
      返回:
      the given string builder

    • appendMd5DigestAsHex

      public static StringBuilder appendMd5DigestAsHex(InputStream inputStream, StringBuilder builder) throws IOException
      Append a hexadecimal string representation of the MD5 digest of the given inputStream to the given StringBuilder.

      This method does not close the input stream.
