x509

Hi,

I wanted to extract the Signer Informations from PKCS#7 Signed Code Image using C/CPP. I wanted to know the openssl API's. I am Able to extract Using bouncy castle (CMSSignedData).

Please let me know the openssl API's which I can use in C/CPP to extract the each signers and signer informations and verify the Signers.

is there any API like X509_LOOKUP_buffer() instead of X509_LOOKUP_file() ???

Thanks in advance opensid
