Ok.
Too bad it seems not to work this way, and $PIN anlways gets translated
to CHV1 :(
If I do
$ pkcs15-init -G rsa/2048 -a 02 -l "test a2"
the card still requires verification of CHVN1 to use the card.
PINs are defined as:
PIN [Card auth]
Object Flags : [0x3], private, modifiable
ID : 01
Flags : [0x30], initialized, needs-padding
Length : min_len:4, max_len:8, stored_len:8
Pad char : 0xFF
Reference : 1
Type : ascii-numeric
Path :
PIN [User auth]
Object Flags : [0x3], private, modifiable
ID : 02
Flags : [0x30], initialized, needs-padding
Length : min_len:4, max_len:8, stored_len:8
Pad char : 0xFF
Reference : 2
Type : ascii-numeric
Path :
so -a 02 should make $PIN get translated to CHV2, not to CHV1 as it
does. Or am I wrong?

I could finally workaround non-working-as-advertised --insecure by
patching profile and w/o touching code:
option default {
macros {
[...]
prkacl = CRYPTO=$PIN, UPDATE=$PIN, DELETE=$PIN,
GENERATE=$PIN;
}
}
option insecure {
macros {
prkacl = CRYPTO=NONE, UPDATE=$PIN, DELETE=$PIN, GENERATE=NONE;
}
}
[...]
EF template-private-key {
[...]
acl = $prkacl;
}
So now I can use
$ pkcs15-init --profile pkcs15+default+insecure -G rsa/2048 --insecure
-l "key usable without PIN"
It's a bit ugly, but makes the user think twice before generating an
insecure key :)
I still think that --insecure should "translate" $PIN to NONE, but
that's another story.
BYtE,
Diego.
