i have following problem:

i have these files

developer_identity.cer

Team_Provisioning_Profile_.mobileprovision

In order to package adobe flex mobile application for iOS, i need to convert my .cer certificate into .p12 format. Following this tutorial on help.adobe.com i always get this problem when executing last openssl command:

"no certificate matches private key
error in pkcs12"

From what i understand i need somehow to get private key, that was used to create the certificate (do i understand this well??). How do i get the private key mykey.key if i only have .cer and .mobileprovision files mentioned above?

The .cer does not contain your private key and you cannot generate your .p12 file from it. You have to export them both at the same time from keychain. If you only have the .cer file, it's useless and you will have to create a new private key and certificate pair.
