c102e3ce4b psa_hmac_start: simplify key_length logic in hash-the-key case 2018-09-12 16:13:49 +03:00

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.

8c9def3e7f PSA: Implement MAC functions 
Implement psa_mac_start, psa_mac_update and psa_mac_final.

Implement HMAC anc CMAC.

Smoke tests.

9ef733faa0 Implement hash functions 
New header file crypto_struct.h. The main file crypto.sh declares
structures which are implementation-defined. These structures must be
defined in crypto_struct.h, which is included at the end so that the
structures can use types defined in crypto.h.

Implement psa_hash_start, psa_hash_update and psa_hash_final. This
should work for all hash algorithms supported by Mbed TLS, but has
only been smoke-tested for SHA-256, and only in the nominal case.

a590529938 Greatly expanded mbedtls_to_psa_error 
It now covers most cryptography algorithm modules (missing: bignum,
DHM, everything ECC, HMAC_DRBG).

20035e3579 PSA crypto: asymmetric signature (RSA PKCS#1v1.5 only) 
Define hash algorithms and RSA signature algorithms.

New function psa_asymmetric_sign.

Implement psa_asymmetric_sign for RSA PKCS#1 v1.5.

969ac726d9 PSA RSA key import: don't rely on pk so much 
Don't use the pk module except as required for pkparse/pkwrite. The
PSA crypto layer is meant to work alongside pk, not on top of it.

Fix the compile-time dependencies on RSA/ECP handling in
psa_export_key, psa_destroy_key and psa_get_key_information.

2f9c4dc5ad Add key management functions 
Define psa_key_type_t and a first stab at a few values.

New functions psa_import_key, psa_export_key, psa_destroy_key,
psa_get_key_information. Implement them for raw data and RSA.

Under the hood, create an in-memory, fixed-size keystore with room
for MBEDTLS_PSA_KEY_SLOT_COUNT - 1 keys.

e59236fc17 Add PSA crypto module 
New module psa_crypto.c (MBEDTLS_PSA_CRYPTO_C):
Platform Security Architecture compatibility layer on top of
libmedcrypto.

Implement psa_crypto_init function which sets up a RNG.

Add a mbedtls_psa_crypto_free function which deinitializes the
library.

Define a first batch of error codes.
