Rather than using the solution in their FAQ (using AES to encrypt/decrypt the file and check in the encrypted file into repo), our solution is more pragmatic. The private key below is incomplete. Only the missing portion is encrypted. Much less secure than the original 2048-bit RSA has to offer but good enough for our case.
