e1bc6800cc psa_hmac_start: remove useless casts 2018-09-12 16:13:49 +03:00
Gilles Peskine
7e454bc19f Split out CMAC and HMAC code into auxiliary functions 
Split algorithm-specific code out of psa_mac_start. This makes the
function easier to read.

The behavior is mostly unchanged. In a few cases, errors before
setting a key trigger a context wipe where they didn't. This is a
marginal performance loss but only cases that are an error in caller
code.

ef057ac8ed Remove dead code 
Remove an unused function and an unused variable. Now the code builds
with gcc -Wall -Wextra -Werror.

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.

ff215726b4 rsa: pss: Use size_t when computing signatures 
Functions like `mbedtls_md_get_size()` and `mgf_mask()` work with
`size_t`. Use local variables with `size_t` to match.

cfeb70c6b9 gmtime: Remove special treatment for IAR 
Previous commits attempted to use `gmtime_s()` for IAR systems; however,
this attempt depends on the use of C11 extensions which lead to incompatibility
with other pieces of the library, such as the use of `memset()` which is
being deprecated in favor of `memset_s()` in C11.
