DEFAULT_DOMAIN_KEY_LENGTH as an environment variable

[vitoyucepi]

Question

Is it possible to specify DEFAULT_DOMAIN_KEY_LENGTH as an environment variable or in account.conf?

Details

I'm trying to use the command acme.sh --issue -d domain.com.
I want to use rsa2048 as a default key algorithm, but it seems impossible without the explicit command line argument -k 2048.

For the first time, keylength is set here

acme.sh/acme.sh

Line 7217 in 0da839c

_keylength="$DEFAULT_DOMAIN_KEY_LENGTH"

I think I can't override the variable because DEFAULT_DOMAIN_KEY_LENGTH at the moment is set here

acme.sh/acme.sh

Line 57 in 0da839c

DEFAULT_DOMAIN_KEY_LENGTH=ec-256

Then it's possible to override it using the command line argument here

acme.sh/acme.sh

Lines 7504 to 7510 in 0da839c

	--keylength | -k)
	_keylength="$2"
	shift
	if [ "$_keylength" ] && ! _isEccKey "$_keylength"; then
	export __SELECTED_RSA_KEY=1
	fi
	;;

After that, it goes straight into the issue command here

acme.sh/acme.sh

Lines 7856 to 7858 in 0da839c

	issue)
	issue "$_webroot" "$_domain" "$_altdomains" "$_keylength" "$_cert_file" "$_key_file" "$_ca_file" "$_reloadcmd" "$_fullchain_file" "$_pre_hook" "$_post_hook" "$_renew_hook" "$_local_address" "$_challenge_alias" "$_preferred_chain" "$_valid_from" "$_valid_to"
	;;

And to the createDomainKey command

acme.sh/acme.sh

Line 4488 in 0da839c

if ! createDomainKey "$_main_domain" "$_key_length"; then

I think it could be overridden here by setting _cdl var in account.conf

acme.sh/acme.sh

Lines 1529 to 1536 in 0da839c

	_cdl=$2
	if [ -z "$_cdl" ]; then
	_debug "Use DEFAULT_DOMAIN_KEY_LENGTH=$DEFAULT_DOMAIN_KEY_LENGTH"
	_cdl="$DEFAULT_DOMAIN_KEY_LENGTH"
	fi
	_initpath "$domain" "$_cdl"
