This commit extends the RSA interface by import/export calls that can be used to setup an RSA context from a subset of the core RSA parameters (N,P,Q,D,E). The intended workflow is the following: 1. Call mbedtls_rsa_import one or multiple times to import the core parameters. 2. Call mbedtls_rsa_complete to deduce remaining core parameters as well as any implementation-defined internal helper variables. The RSA context is ready for use after this call. The import function comes in two variants mbedtls_rsa_import and mbedtls_rsa_import_raw, the former taking pointers to MPI's as input, the latter pointers buffers holding to big-endian encoded MPI's. The reason for this splitting is the following: When only providing an import function accepting const MPI's, a user trying to import raw binary data into an RSA context has to convert these to MPI's first which before passing them to the import function, introducing an unnecessary copy of the data in memory. The alternative would be to have another MPI-based import-function with move-semantics, but this would be in contrast to the rest of the library's interfaces. Similarly, there are functions mbedtls_rsa_export and mbedtls_rsa_export_raw for exporting the core RSA parameters, either as MPI's or in big-endian binary format. The main import/export functions deliberately do not include the additional helper values DP, DQ and QP present in ASN.1-encoded RSA private keys. To nonetheless be able to check whether given parameters DP, DQ and QP are in accordance with a given RSA private key, the interface is extended by a function mbedtls_rsa_check_opt (in line with mbedtls_rsa_check_privkey, mbedtls_rsa_check_pubkey and mbedtls_rsa_check_pub_priv). Exporting the optional parameters is taken care of by mbedtls_export_opt (currently MPI format only). |
