How to Generate Public key for Bank module

[khumair]

HI , I have a question regarding LHV pank module (Estonian bank), LHV bank is asking me to share Public key with them,  so they can generate Private key for our LHV bank module, they shared .pem file with me, 

My question is how i can generate the public key?
they ask me to generate key by using these algorithum

• Signature algorithm – sha1RSA
• Public key – RSA(2048 Bits

I am not familiar with how to use them and generate public in PrestaShop

Need Help
Thanks In Advance

They most likely refer to you generating your SSH key and send them the public one.

This is not something you do from Prestashop but from your server, google for SSH keys.
