Step to generate an RSA PEM (asymmetric) key pair for use with SimpleBackups Encryption
Generating and Using RSA Keys for SimpleBackups This guide will walk you through the steps to generate an RSA private key and derive the corresponding public key for use with SimpleBackups.
Step 1: Generate the Private Key Open a terminal. Run the following command to generate a private RSA key: openssl genrsa -aes256 -out private-key.pem 4096 You will be prompted to enter a password (we recommend securing your keys with a passphrase). Generating RSA private key, 4096 bit long modulus...Enter pass phrase for private-key.pem: Alternative: Generate RSA Key with PSA256 If you need to generate a private key using the PSA256 algorithm, use the following command:
openssl genpkey -algorithm RSA -out private-key-psa256.pem -pkeyopt rsa_keygen_bits:4096 -aes256 You will be prompted to enter a password as well.
Step 2: Obtain the PEM Public Key Use the following command to derive the public key from your private key: openssl rsa -in private-key.pem -pubout -out public-key.pem openssl rsa -in private-key-psa256.pem -pubout -out public-key-psa256.pem View the contents of the public-key.pem or public-key-psa256.pem file using: cat public-key.pem cat public-key-psa256.pem Copy the contents of the respective public key file and paste them into SimpleBackups' encryption key field. Additional Notes 🔒
Security : Ensure that your private key ( private-key.pem or private-key-psa256.pem ) is stored securely. The passphrase adds an additional layer of security
⚙
Usage : The public key ( public-key.pem or public-key-psa256.pem ) will be used by SimpleBackups for encryption purposes. Only share the public key with trusted entities.
