您好，

我有一個.C檔，用FOSSology掃出RSA-Security，請問這是要open source嗎？FOSSology看到的條款如下：

License to copy and use this software is granted provided that it
is identified as the "RSA Data Security, Inc. MD5 Message-Digest
Algorithm" in all material mentioning or referencing this software
or this function.

License is also granted to make and use derivative works provided
that such works are identified as "derived from the RSA Data
Security, Inc. MD5 Message-Digest Algorithm" in all material
mentioning or referencing the derived work.

RSA Data Security, Inc. makes no representations concerning either
the merchantability of this software or the suitability of this
software for any particular purpose. It is provided "as is"
without express or implied warranty of any kind.

These notices must be retained in any copies of any part of this
documentation and/or software.

Hi CW Chung,

這不是open source的規定，依照這樣的授權規定，您可以隨意重製、利用與修改這個軟體，而不需要將原始碼提供給他人。

不過要提醒您，雖然您沒有提供原始碼的義務，但是授權聲明中卻要求您履行其他的義務：

1. 必須在論述到或引用到這個軟體的相關文件中，加上宣揚 "RSA Data Security, Inc." 公司以及 MD5 演算法的特定文字，至於是哪些特定文字，就請依照授權聲明中第一、二段的規定。

2. 此外，這份英文的授權聲明必須雖著軟體或相關文件的副本一起被複製、保留下來，不可刪除。

希望以上的說明對您有所幫助！
