Hanno Becker 1b831fe1c5 Clarify guarantees made by rsa_deduce_moduli/private/crt 2017-10-02 13:06:47 +01:00
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.
 2017-09-29 11:54:05 +01:00
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 b0c5edcc2f Correct typo in rsa.h 2017-08-23 22:16:10 +01:00
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.

Hanno Becker ce00263bd2 Add tests for rsa_check_params 
This commit adds test for the new library function mbedtls_rsa_check_params for
checking a set of RSA core parameters. There are some toy example tests with
small numbers that can be verified by hand, as well as tests with real world
numbers. Complete, partial and corrupted data are tested, as well the check for
primality exactly if a PRNG is provided.
