[security-dev 01741]: Re: '\0' in alias name of a pkcs11 keystore

Slightly off topic.
Something I would like to see is API support for setting aliases when 
using the KeyPairGenerator. This is due to the fact that many HSMs do 
not allow changing an alias of private keys after they have been 
generated. Since the key pair generator sets a blank alias when using 
PKCS#11, HSM key pairs are left with no alias.

You can set an alias by providing it using pkcs11 attributes through the 
provider, but that alias is provider global (for all generated key 
pairs) which is not very usable.
