wget https://www.openssl.org/source/openssl-1.1.1h.tar.gz

Download sha256

wget https://www.openssl.org/source/openssl-1.1.1h.tar.gz.sha256


echo "$(cat openssl-1.1.1h.tar.gz.sha256) openssl-1.1.1h.tar.gz" | sha256sum --check


tar -zxf openssl-1.1.1h.tar.gzcd openssl-1.1.1h./configmakemake testsudo make install

Change symbolic link

There seems to be a certificate configuration issues when I run wget

wget https://www.google.com

ERROR: cannot verify www.google.com's certificate, issued by ‘CN=GTS CA 1O1,O=Google Trust Services,C=US’:

To connect to www.google.com insecurely, use `--no-check-certificate'.

Checking openssl version -d I realized the installation directory have changed to /usr/local/ssl

/usr/lib/ssl (original)

lrwxrwxrwx 1 root root   14 Apr 20  2020 certs -> /etc/ssl/certs
drwxr-xr-x 2 root root 4096 Apr 23  2020 misc
lrwxrwxrwx 1 root root   20 Apr 20  2020 openssl.cnf -> /etc/ssl/openssl.cnf
lrwxrwxrwx 1 root root   16 Apr 20  2020 private -> /etc/ssl/private

/usr/local/ssl (new)

drwxr-xr-x 2 root root  4096 Nov 21 13:02 certs
-rw-r--r-- 1 root root   412 Nov 21 13:02 ct_log_list.cnf

NOTE: certs abd private are empty directory.


cd /usr/local/sslsudo rmdir certssudo ln -s /etc/ssl/certssudo rmdir private/sudo ln -s /etc/ssl/privatesudo mv openssl.cnf openssl.cnf.originalsudo ln -s /etc/ssl/openssl.cnf
