Many thanks for your response but It is still not clear for me ... *blush*

Can someone precise which method/function I have to call to build the key object ? 

I have to affect the signKey field of the xmlSecDSigCtx structure but I do not know how to do that :/ My key is in an Ncipher hardware. I already interact with it through the ENGINE API and then using the opennssl API (ENGINE_load_private_key and, EVP_PKEY_get1_RSA and then RSA_sign) but what should I do to use the xmlSecDSigCtxSign function ?

Aleksey, you told me to build the correct context with a "low level" API but which one ? And what about the openssl API ? I'm totally blind :'( 

The interactions between xmlsec and openssl API is not clear :/

Many thanks for any help

No, it would not work that way. You have to go one level bellow that and manually construct xmlsec Key object (with KeyData) from the openssl key handle and then manually add key to the manager.
