Gilles Peskine d393e18f90 Add psa_set_key_lifetime
It is likely that most implementations won't support this function.
But in case an implementation wants to provide it, standardize its
interface.

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

Implement HMAC anc CMAC.

Smoke tests.
2018-09-05 11:53:25 +03:00
Gilles Peskine 308b91d7db Wrote documentation for several functions, macros and types
Document key import/export functions, hash functions, and asymmetric
sign/verify, as well as some related macros and types.

Nicer formatting for return values: use \retval.
2018-09-05 11:53:25 +03:00
Gilles Peskine 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.
2018-09-05 11:53:25 +03:00
Gilles Peskine a590529938 Greatly expanded mbedtls_to_psa_error
It now covers most cryptography algorithm modules (missing: bignum,
DHM, everything ECC, HMAC_DRBG).
2018-09-05 11:53:24 +03:00
Gilles Peskine 98f0a24255 Improve key type and algorithm encodings
Refine the encoding of key types and algorithms so that ranges of bits
make more sense.

Define a few symmetric cipher algorithms.

2018-09-05 11:53:24 +03:00
Gilles Peskine 20035e3579 PSA crypto: asymmetric signature (RSA PKCS#1v1.5 only)
Define hash algorithms and RSA signature algorithms.

New function psa_asymmetric_sign.

Gilles Peskine c66ea6a921 PSA key import: support RSA public keys
Use different key types for private keys and public keys.
2018-09-05 11:53:24 +03:00
Gilles Peskine 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.
2018-09-05 11:53:24 +03:00
Gilles Peskine 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.
2018-09-05 11:53:24 +03:00
Gilles Peskine 1d26709dbd New function mbedtls_rsa_get_bitlen
Add a new function mbedtls_rsa_get_bitlen which returns the RSA key
size, i.e. the bit size of the modulus. In the pk module, call
mbedtls_rsa_get_bitlen instead of mbedtls_rsa_get_len, which gave the
wrong result for key sizes that are not a multiple of 8.

This commit adds one non-regression test in the pk suite. More tests
are needed for RSA key sizes that are a multiple of 8.

This commit does not address RSA alternative implementations, which
only provide an interface that return the modulus size in bytes.

Gilles Peskine 62a7e7e65f Add a Doxygen-only section
This is intended to document platform-specific definitions in PSA.
2018-09-05 10:59:02 +03:00
Gilles Peskine 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.
