如何獲得服務器的完整證書鏈?儘管有些索賠one should be able to do just that與openssl s_client -showcerts
,但情況並非總是如此。獲取包含根證書的完整證書鏈
echo | openssl s_client -CApath /etc/ssl/certs -connect www.ssllabs.com:443 \
-showcerts | grep -B2 BEGIN
depth=3 C = SE, O = AddTrust AB, OU = AddTrust External TTP Network, CN = AddTrust External CA Root
verify return:1
depth=2 C = GB, ST = Greater Manchester, L = Salford, O = COMODO CA Limited, CN = COMODO RSA Certification Authority
verify return:1
depth=1 C = GB, ST = Greater Manchester, L = Salford, O = COMODO CA Limited, CN = COMODO RSA Domain Validation Secure Server CA
verify return:1
depth=0 OU = Domain Control Validated, OU = PositiveSSL, CN = www.ssllabs.com
verify return:1
0 s:/OU=Domain Control Validated/OU=PositiveSSL/CN=www.ssllabs.com
i:/C=GB/ST=Greater Manchester/L=Salford/O=COMODO CA Limited/CN=COMODO RSA Domain Validation Secure Server CA
-----BEGIN CERTIFICATE-----
--
1 s:/C=GB/ST=Greater Manchester/L=Salford/O=COMODO CA Limited/CN=COMODO RSA Domain Validation Secure Server CA
i:/C=GB/ST=Greater Manchester/L=Salford/O=COMODO CA Limited/CN=COMODO RSA Certification Authority
-----BEGIN CERTIFICATE-----
--
2 s:/C=GB/ST=Greater Manchester/L=Salford/O=COMODO CA Limited/CN=COMODO RSA Certification Authority
i:/C=SE/O=AddTrust AB/OU=AddTrust External TTP Network/CN=AddTrust External CA Root
-----BEGIN CERTIFICATE-----
DONE
這裏我們有三個證書我們四個。所有除AddTrust External CA Root
證書。 (可能是因爲它沒有包含在證書包中,不需要這樣做,是的,我可以在/etc/ssl/certs
找到丟失的文件)
如何以全自動方式獲取服務器的所有證書?
