Hi all: In my debugging process for the new Spanish DNIe LGPL card driver [1], I've found a problem with "pkcs11-tool -O": returns a warning about invalid RSA public key size:
------------------------------
...
warning: PKCS11 function C_GetAttributeValue(MODULUS_BITS) failed: rv =
CKR_ATTRIBUTE_TYPE_INVALID (0x12)
Public Key Object; RSA 0 bits
label: KpuAutenticacion
ID: 4130364236323435383832383133323230313031313131313634303236
Usage: verify
....
----------------------
By using "pkcs15-tool -D" shows me no error:
-----------------
....

--------------------------
AFAIK DNIe is a full pkcs15 compliant card. In fact there is no
emulation layer
I'm not sure about the internal pkcs11 process, nor if this is a bug in
my driver, or a bug in opensc, or if this is the expected way to work
In fact, every pkcs15-tools functions seems to work fine, but
pkcs11-tool functions fails.
Seems that this question (or similar) has appeared already in this list,
but unsure if related. Any hint to start debugging?
Thanks in advance
