OpenSSL在Linux上的日志记录功能如何配置

<code># /etc/syslog.conf 或 /etc/rsyslog.conf
auth,authpriv.* /var/log/secure</code>

<code>sudo systemctl restart syslog  # 对于使用syslog的系统
sudo systemctl restart rsyslog  # 对于使用rsyslog的系统</code>

<code>#include <openssl/err.h>
#include <openssl/ssl.h>
#include <stdio.h>
<p>void openssl_error_handler(const char *file, int line, int err) {
char err_buf[256];
ERR_load_crypto_strings();
ERR_error_string(ERR_get_error(), err_buf);
fprintf(stderr, "OpenSSL error in %s at line %d: %s\n", file, line, err_buf);
ERR_free_strings();
}</p><p>int main() {
// 设置错误处理函数
OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CRYPTO_STRINGS, NULL);
ERR_set_error_data(0, NULL);
ERR_set_error_callback(openssl_error_handler);</p><pre class="brush:php;toolbar:false;"><code>// 你的OpenSSL代码
SSL_CTX *ctx = SSL_CTX_new(TLS_client_method());
if (!ctx) {
    fprintf(stderr, "Failed to create SSL context\n");
    return 1;
}

// 其他操作...

SSL_CTX_free(ctx);
OPENSSL_cleanup_crypto_strings();
return 0;</code>

<code>export OPENSSL_DEBUG=1</code>

<code>[default]
ssl_conf = ssl_sect</p><p>[ssl_sect]
system_default = system_default_sect</p><p>[system_default_sect]
MinProtocol = TLSv1.2
CipherString = DEFAULT@SECLEVEL=1</code>

<code>SSL_CTX *ctx = SSL_CTX_new_with_config(NULL, "openssl.cnf");</code>
