I'm tring to create python script, that would take PKCS#12 package and print some information contained in x509 certificate and using for this purpouses PyOpenSSL module. So far i want to fetch from certificate public key. But PKey object doesn't have appropriate method. Where can I move out of here ? Any ideas how to get public key ?

pfx=open('./1.p12','rb').read()
PKCS=crypto.load_pkcs12(pfx)
cert=PKCS.get_certificate()
PKey=cert.get_pubkey()print PKey
<OpenSSL.crypto.PKey object at 0x012432D8>

Thanks.

First you can load the certificate like this

from OpenSSL import crypto#cert is the encrypted certificate int this format -----BEGIN -----END    
crtObj = crypto.load_certificate(crypto.FILETYPE_PEM, cert)
pubKeyObject = crtObj.get_pubkey()
pubKeyString = crypto.dump_publickey(crypto.FILETYPE_PEM,pubKeyObject)
print pubKeyString

you will see something like

-----BEGIN PUBLIC KEY----- 
....
....
-----END PUBLIC KEY-----
