How to generate an RSA PEM (asymmetric) key pair?

Step to generate an RSA PEM (asymmetric) key pair for use with SimpleBackups Encryption

Step 1. Generate the private key

Open a terminal and run the following command

openssl genrsa -aes256 -out private-key.pem 4096
 

You will be prompted to enter a password (we recommend securing your keys by a pass phrase).

Generating RSA private key, 4096 bit long modulus... Enter pass phrase for private-key.pem:

Step 2. Obtain the PEM public key to use

Using the following command, pass your private key we just generated:

openssl rsa -in private-key.pem -pubout > public-key.pem
 

Copy and paste the contents of the public-key.pem file we obtained, and paste that into SimpleBackups' encryption key field.

cat public-key.pem
