Details

The my_key() function checks environment variable USER_KEY for a path to a private keyfile. If unset it defaults to "~/.ssh/id_rsa".

The my_pubkey() function first tries USER_PUBKEY and if unset it checks for USER_KEY to derive the corresponding pubkey. If both are unset it defaults to "~/.ssh/id_rsa.pub".

# Set random RSA key as default
key <- rsa_keygen()
write_pem(key, tmp <- tempfile(), password = "")
rm(key)
Sys.setenv("USER_KEY" = tmp)

# Check the new keys
print(my_key())
print(my_pubkey())
