ValueError: unsupported hash type shaXXX error when try to run yum to install package on AIX

When try to use yum on AIX you may face the following error:

As you can see is something related to hash.

After checking the system with the command rpm -qa I noticed that a very old version of openssl, from 2002, was installed, so I just removed it, no impact for the system as all is to use the native ssl version installed on AIX:

[root@server1]/mnt/> rpm -e openssl-0.9.6b-3.ppc openssl-doc-0.9.6b-3.ppc
warning: /var/ssl/openssl.cnf saved as /var/ssl/openssl.cnf.rpmsave
[root@server1]/mnt/>

Remember to recreate the file /var/ssl/openssl.cnf.rpmsave to avoid any issues

cp -p /var/ssl/openssl.cnf.rpmsave /var/ssl/openssl.cnf
