The upgrade is now working fine in one of the applications which make TLS
connections. I can see the engine functions being called when some action
(sign/verify) which require the privatekey.
However, this engine is also used in a patched version of Racoon2.
In one of the files (crypto_openssl.c) a function is called by the IKE daemon
(iked) during setup with:
:
EVP_SignInit(&ctx, md);
EVP_SignUpdate(&ctx, octets->v, octets->l);
EVP_SignFinal(&ctx, (unsigned char*)sig->v, &siglen, pkey);
:
With the upgraded OpenSSL v1.0.2, the last function now fails with the error:
2017-08-28 15:44:14 [INTERNAL_ERR]:
crypto_openssl.c:1238:eay_rsassa_pkcs1_v1_5_sign(): RSA_sign failed:
30972:error:0606B06E:digital envelope routines:EVP_SignFinal:wrong public key
type:p_sign.c:123:
Q: I assume it is looking for one of the missing parameters (p) in the RSA
structure - correct?
Q: If so, how did it work in v0.9.8?
If I change the first command to:
EVP_SignInit_ex(&ctx, md, engine);
Then it segfaults in the "SignFinal" command :(
The engine is dynamically loaded the same way in both my TLS connection
application and in the Racoon2 application.
Thanks for your time - any help is appreciated!

Thanks for the help.
I've come to learn that my problem is the HSM. It removes the RSA values p,q
and d from the EVP key before returning it. This is normal since it is
protecting the key by keeping it in the HSM - duh. Anyway so, I cannot use it
as a normal key. "Live and learn"
So this bring me to the next question: Is there any changes I need to make in
the OpenSSL Engine for my upgrade (0.9.8 -> 1.0.2) to be complete?

Subject: [openssl-dev] Upgrading OpenSSL
Hi all,
I am task to update two machines from v0.9.8z to v1.0.2 (since it is LTS).
With the minimal changes, I've been able to get the application on the machines
to compile with the newer version and generate RSA 4096 key pairs. The
applications are able to successfully use their respective private keys and
certificates to establish TLS connection between them. However, when I used the
CLI to check a dumped privatekey i got the following output:
% openssl rsa -check -in privkey.pem
unable to load Private Key
1995859152:error:0D078079:asn1 encoding routines:ASN1_ITEM_EX_D2I:field

1995859152:error:0907B00D:PEM routines:PEM_READ_BIO_PRIVATEKEY:ASN1
lib:pem_pkey.c:141:
Any suggestions at what is wrong with the key?
Note that an ID is stored in the RSA extended data since the private key may be
stored in HSM.
Thanks for your time
