nginx 的 ngx_http_auth_basic_module 模块，校验密码一般是通过 apr1 算法（ MD5 迭代 1000 ）实现的吧，不安全。我们自己 web 服务校验是使用 pbkdf2 算法，但是使用的某些开源组件需要走 nginx 进行 basic 认证。想问下有没有现成的插件实现了更安全的算法，还是有其他更好的方案做密码校验？

@johnniang htpasswd 有 bcryte 算法，但是 ngx_http_auth_basic_module 不支持

直接调用 libc.so 的
libc.so 支持就行

怎么可能不支持？

http://nginx.org/en/docs/http/ngx_http_auth_basic_module.html

The following password types are supported:

encrypted with the crypt() function; can be generated using the “htpasswd” utility from the Apache HTTP Server distribution or the “openssl passwd” command;
hashed with the Apache variant of the MD5-based password algorithm (apr1); can be generated with the same tools;
specified by the “{scheme}data” syntax (1.0.3+) as described in RFC 2307; currently implemented schemes include PLAIN (an example one, should not be used), SHA (1.3.13) (plain SHA-1 hashing, should not be used) and SSHA (salted SHA-1 hashing, used by some software packages, notably OpenLDAP and Dovecot).

@Xusually 不支持咯，https://github.com/nginx/nginx/blob/master/src/core/ngx_crypt.c

你看下代码，最后的 fallback：

/* fallback to libc crypt() */

return ngx_libc_crypt(pool, key, salt, encrypted);

libc crypt()支持的都可以，至于你提到的 pbkdf2 我不清楚。
