2 证书问题

OpenSSL 与 CRL 一起使用,对于证书链中的某些 CA,其 CRL 不包括在 "TLSCRLFile" 中

OpenSSL 对端的情况下,在 TLS 服务器日志中,会有如下显示:

failed to accept an incoming connection: from 127.0.0.1: TLS handshake with 127.0.0.1 returned error code 1: \
           file s3_srvr.c line 3251: error:14089086: SSL routines:ssl3_get_client_certificate:certificate verify failed: \
           TLS write fatal alert "unknown CA"

GnuTLS 对端的情况下,在 TLS 服务器日志中,会有如下显示:

failed to accept an incoming connection: from 127.0.0.1: TLS handshake with 127.0.0.1 returned error code 1: \
           file rsa_pk1.c line 103: error:0407006A: rsa routines:RSA_padding_check_PKCS1_type_1:\
           block type is not 01 file rsa_eay.c line 705: error:04067072: rsa routines:RSA_EAY_PUBLIC_DECRYPT:paddin

CRL 已过期或者在服务器操作期间过期

OpenSSL, 在服务器日志中会议如下显示:

  • 到期前:
cannot connect to proxy "proxy-openssl-1.0.1e": TCP successful, cannot establish TLS to [[127.0.0.1]:20004]:\
           SSL_connect() returned SSL_ERROR_SSL: file s3_clnt.c line 1253: error:14090086:\
           SSL routines:ssl3_get_server_certificate:certificate verify failed:\
           TLS write fatal alert "certificate revoked"
  • 到期后:
cannot connect to proxy "proxy-openssl-1.0.1e": TCP successful, cannot establish TLS to [[127.0.0.1]:20004]:\
           SSL_connect() returned SSL_ERROR_SSL: file s3_clnt.c line 1253: error:14090086:\
           SSL routines:ssl3_get_server_certificate:certificate verify failed:\
           TLS write fatal alert "certificate expired"

这里需要注意的是,使用有效的 CRL,吊销的证书将报告为"证书已吊销"。当 CRL 过期时,错误消息将更改为"证书已过期",这非常具有误导性。

GnuTLS, 在服务器日志中会议如下显示:

  • 到期前后显示相同:
cannot connect to proxy "proxy-openssl-1.0.1e": TCP successful, cannot establish TLS to [[127.0.0.1]:20004]:\
             invalid peer certificate: The certificate is NOT trusted. The certificate chain is revoked.

自签证书,未知CA

OpenSSL, 在日志中显示:

error:'self signed certificate: SSL_connect() set result code to SSL_ERROR_SSL: file ../ssl/statem/statem_clnt.c\
             line 1924: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed:\
             TLS write fatal alert "unknown CA"'

当服务器证书错误地具有相同的颁发者和主题字符串时,尽管该字符串是由 CA 签名的,但颁发者和主题在顶级 CA 证书中相同,但在服务器证书中不能相同时,就会看到这种情况。(这同样适用于proxy和agent证书。)
