Chil HSM needs to create its own request

[Javex]

If a request ist generated with OpenSSL and the chil engine instead of using nCipher's generatekey, the resulting CSR is rejected by an SCEP server (but sscep will accept it and send a request). Thus, the Chil implementation currently needs to use its own createrequest function instead of the default OpenSSL one.

This may be due to an engine issue and should be investigated.
