我从源代码编译Git 1.7.7，同时在MacOS X 10.7上得到关于SHA1_Init和其他相关函数的警告（我使用的是10.7.2，虽然我有XCode 4.2，但我正在编译一个自制的GCC 4.6.1，但只更改警告消息中的详细信息）。
标题是 /usr/include/openssl/sha.h;它包含通知，例如：
int SHA_Init(SHA_CTX *c) DEPRECATED_IN_MAC_OS_X_VERSION_10_7_AND_LATER;
- 有没有人知道在哪里记录为什么SHA1被Apple弃用以及建议的替代品是什么？
说明性消息：

Grumble：我还不能创建新的标签'sha1'，'openssl'和'deprecated'，我认为这可能是合适的。
