Gilles Peskine e9191ff90b Add missing const for signature parameter of psa_asymmetric_verify 2018-09-12 16:24:51 +03:00
Gilles Peskine 08bac713df Clarify that asymmetric_{sign,verify} operate on a hash 2018-09-12 16:24:51 +03:00
Gilles Peskine 55bf3d1171 Sort out RSA mechanisms 
* PSS needs to be parametrized by a hash.
* Don't use `_MGF1` in the names of macros for OAEP and PSS. No one
  ever uses anything else.
* Add brief documentation for the RSA signature mechanisms.

Gilles Peskine 9e73ff17d4 Add missing parameters to some documentation 
tests/scripts/doxygen.sh now passes.

Gilles Peskine 7ed29c56f1 Rename PSA_ALG_RSA_GET_HASH to PSA_ALG_SIGN_GET_HASH 
And don't use it for HMAC when there's a perfectly serviceable
PSA_ALG_HMAC_HASH. HMAC isn't hash-and-sign.

Jaeden Amero 7baf0d5702 psa: doxygen: Fix parameters reference 
Doxygen interprets `\param` as starting documentation for a new param, or
to extend a previously started `\param` documentation when the same
reference is used. The intention here was to reference the function
parameter, not extend the previous documentation. Use `\p` to refer to
function parameters.

Gilles Peskine e9a0a9d74d Update documentation of psa_success_t 
Now that the type is not an enum, explain what values are valid.

Also add a comment to explain the #if defined(PSA_SUCCESS) temporary hack.

itayzafrir c2a7976886 PSA Crypto error code definitions 
Removed the psa_status_t enum and defined error codes as defines.
Conditionally defining PSA_SUCCESS and psa_status_t.

Gilles Peskine 48c0ea14c6 Remove PSA_KEY_TYPE_IS_RAW_BYTES from crypto.h 
It isn't used to define other macros and it doesn't seem that useful
for users. Remove it, we can reintroduce it if needed.

Define a similar function key_type_is_raw_bytes in the implementation
with a clear semantics: it's a key that's represented as a struct
raw_data.

Gilles Peskine 4e69d7a9a7 psa_generate_key: pass parameters_size argument 
When calling psa_generate_key, pass the size of the parameters buffer
explicitly. This makes calls more verbose but less error-prone. This
also has the benefit that in an implementation with separation, the
frontend knows how many bytes to send to the backend without needing
to know about each key type.

Gilles Peskine e1fed0de18 Define elliptic curve identifiers from TLS 
Instead of rolling our own list of elliptic curve identifiers, use one
from somewhere. Pick TLS because it's the right size (16 bits) and
it's as good as any.
 2018-09-12 16:19:04 +03:00
Gilles Peskine b3e6e5deeb Rename hash max sizes for consistency 
Use "hash" throughout the library, not "md" as in Mbed TLS.
 2018-09-12 16:19:04 +03:00
Gilles Peskine 2d2778650b Normalize whitespace 
Normalize whitespace to Mbed TLS standards. There are only whitespace
changes in this commit.

Gilles Peskine 6de7a179c8 Fix file permissions 
Some files were marked as executable but shouldn't have been.
 2018-09-12 16:13:49 +03:00
Nir Sonnenschein 5ca6547b77 Renamed hmac_ctx to opad and removed null check. 
this array is now part of the struct and not dynamically allocated
so it can't be null.

Nir Sonnenschein 9e2ffe83ac change type of hash block to uint8_t 2018-09-12 16:13:49 +03:00
Nir Sonnenschein 35dfbf4601 change hmac context to use statically allocated memory 
1. removed dynamic allocation of stack context
2. moved ipad to stack
3. added defines for maximal sizes
 2018-09-12 16:13:49 +03:00
Nir Sonnenschein dcd636a73f Commit changes to hmac to not use MD abstraction 
this PR is part of efforts to use "lower level" mbedTLS APIs vs "higher level" abstract APIs.

Gilles Peskine 625b01c9c3 Add OAEP placeholders in asymmetric encrypt/decrypt 
Replace PSS placeholders by OAEP placeholders. PSS is a signature
algorithm, not an encryption algorithm.

Fix typo in PSA_ALG_IS_RSA_OAEP_MGF1.

Gilles Peskine 723feffe15 Fix some errors in PSA_ASYMMETRIC_DECRYPT_OUTPUT_SIZE 
A call to PSA_ASYMMETRIC_DECRYPT_OUTPUT_SIZE wouldn't even have
compiled. Fix some obvious errors. This is still untested.
