cc209ca56d Remove signature verification from rsa_rsassa_pkcs1_v15_sign 
This verification path is redundant now that verification is uniformly done in
rsa_private.

c6075cc5ac Don't use CRT for signature verification 
If CRT is not used, the helper fields CRT are not assumed to be present in the
RSA context structure, so do the verification directly in this case. If CRT is
used, verification could be done using CRT, but we're sticking to ordinary
verification for uniformity.

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.

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.

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.

4a7f6a0ddb RSA: wipe stack buffers

rsa_rsaes_oaep_decrypt put sensitive data (decryption results) on the
stack. Wipe it before returning.

f9203b4139 Add exponent blinding to RSA with CRT 
The sliding window exponentiation algorithm is vulnerable to
side-channel attacks. As a countermeasure we add exponent blinding in
order to prevent combining the results of different measurements.

This commit handles the case when the Chinese Remainder Theorem is used
to accelerate the computation.

e81102e476 Add exponent blinding to RSA without CRT

order to prevent combining the results of fifferent measurements.

used to accelerate computations.

c1380de887 RSA PKCS1v1.5 verification: check padding length 
The test case was generated by modifying our signature code so that it
produces a 7-byte long padding (which also means garbage at the end, so it is
essential in to check that the error that is detected first is indeed the
padding rather than the final length check).

ef44178474 Restore P>Q in RSA key generation (#558) 
The PKCS#1 standard says nothing about the relation between P and Q
but many libraries guarantee P>Q and mbed TLS did so too in earlier
versions.

This commit restores this behaviour.

4d04cdcd12 Fix RSA mutex fix 
Once the mutex is acquired, we must goto cleanup rather that return.
Since cleanup adjusts the return value, adjust that in test cases.

Also, at cleanup we don't want to overwrite 'ret', or we'll loose track of
errors.

88fca3ef0e Fix thread safety issue in RSA operations 
The race was due to mpi_exp_mod storing a Montgomery coefficient in the
context (RM, RP, RQ).

The fix was verified with -fsanitize-thread using ssl_pthread_server and two
concurrent clients.

A more fine-grained fix should be possible, locking just enough time to check
if those values are OK and set them if not, rather than locking for the whole
mpi_exp_mod() operation, but it will be for later.

c70b982056 OID functionality moved to a separate module. 
A new OID module has been created that contains the main OID searching
functionality based on type-dependent arrays. A base type is used to
contain the basic values (oid_descriptor_t) and that type is extended to
contain type specific information (like a pk_alg_t).

As a result the rsa sign and verify function prototypes have changed. They
now expect a md_type_t identifier instead of the removed RSA_SIG_XXX
defines.

All OID definitions have been moved to oid.h
All OID matching code is in the OID module.

The RSA PKCS#1 functions cleaned up as a result and adapted to use the
MD layer.

The SSL layer cleanup up as a result and adapted to use the MD layer.

The X509 parser cleaned up and matches OIDs in certificates with new
module and adapted to use the MD layer.

The X509 writer cleaned up and adapted to use the MD layer.

Apps and tests modified accordingly

b386913f8b Split up the RSA PKCS#1 encrypt, decrypt, sign and verify functions 
Split rsa_pkcs1_encrypt() into rsa_rsaes_oaep_encrypt() and
rsa_rsaes_pkcs1_v15_encrypt()
Split rsa_pkcs1_decrypt() into rsa_rsaes_oaep_decrypt() and
rsa_rsaes_pkcs1_v15_decrypt()
Split rsa_pkcs1_sign() into rsa_rsassa_pss_sign() and
rsa_rsassa_pkcs1_v15_sign()
Split rsa_pkcs1_verify() into rsa_rsassa_pss_verify() and
rsa_rsassa_pkcs1_v15_verify()

The original functions exist as generic wrappers to these functions.
