Hanno Becker 7471631dde Make input arguments to mbedtls_rsa_import_raw constant
Original intention was to be allowed to perform in-place operations like changing the byte-order before importing
parameters into an HSM. Now a copy is needed in this case, but there's no more danger of a user expecting the arguments
to be left untouched.

Hanno Becker 43a08d029e Clarify guarantees made by rsa_check_privkey and rsa_complete
Document explicitly that `mbedtls_rsa_check_privkey` and `mbedtls_rsa_complete` succeeding does not guarantee the
consistency of the underlying RSA private key but only that enough information is present to perform a private key
operation.

Hanno Becker bdefff1dde Change signature of mbedtls_rsa_deduce_private
Make input arguments constant and adapt the implementation to use a temporary instead of in-place operations.

Hanno Becker ba5b755f1a Change signature and semantics of mbedtls_rsa_deduce_moduli
Input arguments are marked as constant. Further, no double-checking is performed when a factorization of the modulus has
been found.

Hanno Becker e1582a832b Add expectation when testing RSA key import/export
This commit adds a flag to the RSA import/export tests indicating whether it is
expected that a full RSA keypair can be set up from the provided parameters.

Further, the tests of `mbedtls_rsa_import` and `mbedtls_rsa_import_raw` are
expanded to perform key checks and an example encryption-decryption.

Hanno Becker 2f8f06aa25 Don't always recompute context length in mbedtls_rsa_get_len
This commit changes the implementation of `mbedtls_rsa_get_len` to return
`ctx->len` instead of always re-computing the modulus' byte-size via
`mbedtls_mpi_size`.

Hanno Becker 54cfc585cd Add test cases for mbedtls_rsa_import[_raw] where N is missing 2017-09-29 11:54:05 +01:00
Hanno Becker 2cca6f3290 Always deduce N from P, Q in mbedtls_rsa_complete
Previously, a parameter set of (-, P, Q, -, E) was completed, but (-, P, Q, D,
E) wasn't - this is odd.

Hanno Becker 45037ceac5 Add check for presence of relevant parameters in mbedtls_rsa_private
If CRT is used, check for the presence N, P, Q, D, E, DP, DQ and QP. If CRT is
not used, check for N, P, Q, D, E only.

Hanno Becker d363799a9d Add mbedtls_rsa_validate_crt
This commit adds the function mbedtls_rsa_validate_crt for validating a set of CRT parameters. The function
mbedtls_rsa_check_crt is simplified accordingly.

Hanno Becker fb81c0ec2e Guard primality checks in RSA module by MBEDTLS_GENPRIME
Primality testing is guarded by the configuration flag MBEDTLS_GENPRIME and used in the new RSA helper functions. This
commit adds a corresponding preprocessor directive.

Hanno Becker ab3773123c Add support for alternative RSA implementations
Alternative RSA implementations can be provided by defining MBEDTLS_RSA_ALT in
config.h, defining an mbedtls_rsa_context struct in a new file rsa_alt.h and
re-implementing the RSA interface specified in rsa.h.

Through the previous reworkings, the adherence to the interface is the only
implementation obligation - in particular, implementors are free to use a
different layout for the RSA context structure.
