mostly stylistic nits inline, but also a comment w.r.t. FWICT needles ABI
breakage.

At least write out the acronym "external account binding" out once here,
or maybe expand the method name "external_account_binding", for clarity.

This needlessly breaks older call sites though? Why not keep the plain hash
here, you do not really win anything by switching to a hash ref, or?
Let's avoid churn w.r.t. breaking older package dependencies, if not really
required..

nit: eab doesn't need quoting
And if you keep the method signature to accept a hash (not a hash reference)
here you could do something like:
if (my $eab = $info{eab}) {
my $eab_hmac_key = decode_base64($eab->{hmac_key});
# ..
}
> + my $eab_hmac_key = decode_base64($info->{'eab'}->{hmac_key});
nit: inconsistent hash key quoting in the same statement
