Hm, i Have not seen any errors around this, might this be a platform specific issue?

[ammar92]

Interesting. Do you have an example certificate/ input that triggers this and by any chance an output of the error?

@underdarknl it is found using make kat from the main branch on an Ubuntu 22.04 system
@ammar92 the linked issue contains the full error, it triggers for an ellipticcurve-certificate, as RSA is checked first.

Ah yes, that would make sense. Not every algorithm works the same. although i would think they at least would have a x509 attribute. Ill play around tomorrow.

@underdarknl did you manage to solve the problem?
