export-object: Recover public key from algorithm specific attributes #568

Closed ueno closed 1 year ago

ueno commented 1 year ago

Some tokens such as SoftHSMv2 omit CKA_PUBLIC_KEY_INFO when it can be derived from algorithm specific attributes, such as CKA_MODULUS and CKA_PUBLIC_EXPONENT for RSA. This adds support for it if libtasn1 is available at compile time.

Fixes: #555

I have tested the command manually together with valgrind. Seems to work fine.
