security Export/import

export [-k keychain] [-t type] [-f format] [-w] [-p format] [-P passphrase] [-o outfile]
            Export one or more items from a keychain to one of a number of external representations.  If
            keychain isn't provided, items will be exported from the user's default keychain.

   import inputfile [-k keychain] [-t type] [-f format] [-w] [-P passphrase] [options...]
            Import one or more items from inputfile into a keychain. If keychain isn't provided, items will
            be imported into the user's default keychain.

            Options:
            -k keychain     Specify keychain into which item(s) will be imported/exported.
            -t type         Specify the type of items to import/export.

                            Import types are: cert, pub, priv, session,
                            cert, and agg. Pub, priv, and session refer to keys; agg is one of the
                            aggregate types (pkcs12 and PEM sequence). The command can often figure out what
                            item_type an item contains based in the filename and/or item_format.

                            Export types are: certs, allKeys, pubKeys, privKeys, identities, and all.
                            The default is all. An identity consists of both
                            a certificate and the corresponding provate key.

            -f format       Specify the format of the exported data. Possible formats are openssl, bsafe,
                            raw, pkcs7, pkcs8, pkcs12, x509, openssh1, openssh2, and pemseq. The command can
                            often figure out what format an item is in based in the filename and/or
                            item_type.  The default is openssl if one key
                            is being exported. The default is x509 if one certificate is being exported.

            -w              Specify that private keys are wrapped and must be unwrapped on import/export.
            -x              Specify that private keys are non-extractable after being imported.
            -p              Specifies that PEM armour is to be applied to the exports output data.
            -P passphrase   Specify the unwrapping passphrase immediately. The default is to obtain a secure
                            passphrase via GUI.
            -o outfile      Write the output data to outfile. Default is to write data to stdout.
            -a attrName attrValue
                            Specify optional extended attribute name and value. Can be used multiple times.
                            This is only valid when importing keys.
            -A              Allow any application to access the imported key without warning (insecure, not
                            recommended!)
            -T appPath      Specify an application which may access the imported key (multiple -T options
                            are allowed)
