Hi,
Quick question about skcipher algorithms supporting only
a single keysize, i.e. having min_keysize = max_keysize:
Do I need to do a key size check here or does the crypto
API already ensure the key size is between min and max?
(and therefore guaranteed to be always correct here)
Just trying to avoid posting a redundant patch here :-)

You don't need to.
