[openssl-users] Specify algorithm for openssl smime decrypt

I need to decrypt some  S/MIME content with an invalid key length for 
the AlgOID specified in the PCKS7 content.

AES-256 is specified as the AlgOID, but a key length of 192 bits is 
being used.

Is there anyway to get openssl to decrypt this using the openssl smime 
command? i.e. override the cipher used so that is uses aes-192-cbc ?
