When I try to CURL a website I get SSL error
I installed Ubuntu 20 on my VPS. This is why I'm trying to do:
curl -v https://imenik.tportal.hr/show?action=pretraga&type=bijeleStranice
[1] 438975
root@vps:/var/www/html/tportal# * Trying 195.29.166.100:443...
* TCP_NODELAY set
* Connected to imenik.tportal.hr (195.29.166.100) port 443 (#0)
* ALPN, offering h2
* ALPN, offering http/1.1
* successfully set certificate verify locations:
* CAfile: /etc/ssl/certs/ca-certificates.crt
CApath: /etc/ssl/certs
* TLSv1.3 (OUT), TLS handshake, Client hello (1):

* Closing connection 0
curl: (35) error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol
But when I try like this, it kinda works
curl -v http://imenik.tportal.hr/show?action=pretraga&type=bijeleStranice

I can't find a solution to this SSL problem
The Website uses the old TLS protocol version 1.0, which has been disabled by default since Ubuntu 20.04.
To temporarily override the default for your curl
command, you can create a config file somewhere (e.g. ~/.openssl_allow_tls1.0.cnf
with following content:
openssl_conf = openssl_init
[openssl_init]
ssl_conf = ssl_sect
[ssl_sect]
system_default = system_default_sect
[system_default_sect]
CipherString = DEFAULT@SECLEVEL=1
Then run your command like this:
OPENSSL_CONF=~/.openssl_allow_tls1.0.cnf curl -v https://imenik.tportal.hr/show?action=pretraga&type=bijeleStranice
(this will only set OPENSSL_CONF
for that single command)
or
export OPENSSL_CONF=~/.openssl_allow_tls1.0.cnf
curl -v https://imenik.tportal.hr/show?action=pretraga&type=bijeleStranice
(this will only set OPENSSL_CONF
for the current session or script)
You could also set it globally in /etc/ssl/openssl.cnf
, but it has been disabled for good reasons and I would only override that when necessary.
(via)
Edit the openssl.conf
file:
sudo nano /etc/ssl/openssl.cnf
Add this line at the top:
openssl_conf = openssl_init
And add these lines at the end:
[openssl_init]
ssl_conf = ssl_sect
[ssl_sect]
system_default = system_default_sect
[system_default_sect]
CipherString = DEFAULT@SECLEVEL=1
It works for me. :)
