| Export/Import Credentials |
| ========================= |
| |
| Sometimes, one may need to export credentials (e.g., certificate and private key) from |
| one machine, and import them into another machine. This requires a secured container for |
| sensitive information. We define **SafeBag**, which contains both an NDN certificate |
| (:doc:`version 2.0 <certificate-format>`) and the corresponding private |
| key which is encrypted in `PKCS#8 format <https://tools.ietf.org/html/rfc5208>`_. |
| |
| The format of **SafeBag** is defined as: |
| |
| :: |
| |
| SafeBag = SAFE-BAG-TYPE TLV-LENGTH |
| CertificateV2 ; a data packet following certificate format spec |
| EncryptedKeyBag |
| |
| EncryptedKeyBag = ENCRYPTED-KEY-BAG-TYPE TLV-LENGTH |
| *OCTET ; private key encrypted in PKCS#8 format |
| |
| All TLV-TYPE codes are application specific: |
| |
| +---------------------------------------------+-------------------+----------------+ |
| | TLV-TYPE | Assigned number | Assigned number| |
| | | (decimal) | (hexadecimal) | |
| +=============================================+===================+================+ |
| | SafeBag | 128 | 0x80 | |
| +---------------------------------------------+-------------------+----------------+ |
| | EncryptedKeyBag | 129 | 0x81 | |
