嵌入式系统文件加密库 [英] Embedded systems file encryption library

问题描述

我有一个项目，其中一部分是加密到FAT文件系统中。

I've got a project and a part of it is incorporating encryption into a FAT file system.

项目的目标不是加密，所以我我可以自由地使用开源的预完成的库。

The goal of the project is not the encryption, so I'm free to use open-source pre-done libraries.

理想情况下，我使用的是使用RSA的C库，它已经具有计算密钥的方法并加密/解密文件。

Ideally what I'm after is a C library which uses RSA, that already has the methods for computing keys and encrypting/decrypting files.

推荐答案

您可能需要查看NaCl （发音为salt），特别是因为这是一个嵌入式系统。

You might want to check out NaCl (pronounced as "salt"), especially since this is for an embedded system.

它具有CPU-特定的调整，并且不需要任何动态内存分配。

It has CPU-specific tunings and doesn't require any dynamic memory allocation.

关于许可，页面（上面链接）说所有的NaCl软件都在公共领域 。

As for licensing, the page (linked above) says "All of the NaCl software is in the public domain".
