Not built-in. Try openssl's crypto library.
不是内置的。试试 openssl 的加密库。

#include <openssl/sha.h>
int main()
{
const unsigned char str[] = "Original String";
unsigned char hash[SHA_DIGEST_LENGTH]; // == 20
SHA1(str, sizeof(str) - 1, hash);
// do some stuff with the hash
return 0;
}
Link with -lssl, which will imply -lcrypto. If you are linking statically you might need to link both.
与 链接-lssl，这将暗示-lcrypto。如果您是静态链接，则可能需要同时链接两者。

Check out this post on Ubuntu Forums. They suggest looking in libcrypt.
在 Ubuntu 论坛上查看这篇文章。他们建议查看libcrypt。
Also there's an implementation herebut I'm not sure what the license is.
