Gilles Peskine 89d8c5c447 Rename some signature-related identifiers
Rename some macros and functions related to signature which are
changing as part of the addition of psa_sign_message and
psa_verify_message.

Gilles Peskine 178c9aa966 Key derivation: forbid output_key without input_key
If none of the inputs to a key derivation is a
PSA_KEY_DERIVATION_INPUT_SECRET passed with
psa_key_derivation_input_key(), forbid
psa_key_derivation_output_key(). It usually doesn't make sense to
derive a key object if the secret isn't itself a proper key.

Gilles Peskine 224b0d656a Key derivation: allow both keys and direct inputs
Allow a direct input as the SECRET input step in a key derivation, in
addition to allowing DERIVE keys. This makes it easier for
applications to run a key derivation where the "secret" input is
obtained from somewhere else. This makes it possible for the "secret"
input to be empty (keys cannot be empty), which some protocols do (for
example the IV derivation in EAP-TLS).

Conversely, allow a RAW_DATA key as the INFO/LABEL/SALT/SEED input to a key
derivation, in addition to allowing direct inputs. This doesn't
improve security, but removes a step when a personalization parameter
is stored in the key store, and allows this personalization parameter
to remain opaque.

Add test cases that explore step/key-type-and-keyhood combinations.

Gilles Peskine ed87d31d7d Specify the order of inputs for TLS-1.2 KDFs
From the implementation point of view does not make much difference to
constrain the input order.

We constrain it because, this way the code is easier to review, the data
flow easier to understand and the implementations in general are easier
to validate.

Convert the description of PSA_ALG_TLS12_PRF and
PSA_ALG_TLS12_PSK_TO_MS to the key derivation API that takes one input
at a time rather than the old {secret,salt,label} interface.

Define a new input category "seed".

Gilles Peskine 4b3eb69271 Rename PSA_ERROR_TAMPERING_DETECTED to ..._CORRUPTION_DETECTED
“Tampering detected” was misleading because in the real world it can
also arise due to a software bug. “Corruption detected” is neutral and
more precisely reflects what can trigger the error.

Move DSA-related key types and algorithms to the
implementation-specific header file. Not that we actually implement
DSA, but with domain parameters, we should be able to.

Gilles Peskine dcaefae849 Parametrize Diffie-Hellman keys by a group identifier
Parametrize finite-field Diffie-Hellman key types with a DH group
identifier, in the same way elliptic curve keys are parametrized with
an EC curve identifier.

Define the DH groups from the TLS registry (these are the groups from
RFC 7919).

Replicate the macro definitions and the metadata tests from elliptic
curve identifiers to DH group identifiers.

Define PSA_DH_GROUP_CUSTOM as an implementation-specific extension for
which domain parameters are used to specify the group.

Define a range of key identifiers for use by the application

range that is reserved for future use (2^31..2^32-1).

Gilles Peskine 3e79c8ecfd Declare ChaCha20 cipher and AEAD
Declare algorithms for ChaCha20 and ChaCha20-Poly1305, and a
corresponding (common) key type.

Don't declare Poly1305 as a separate algorithm because it's a one-time
authenticator, not a MAC, so the API isn't suitable for it (no way to
use a nonce).

Gilles Peskine 679693ee49 Algorithm encoding: add flag bit PSA_ALG_AEAD_FROM_BLOCK_FLAG

Gilles Peskine a52460c3ed Algorithm encoding: move two bits from derivation to agreement
This gives a little more room to encode key agreement algorithms,
while keeping enough space for key derivation algorithms.

This doesn't affect any of the already-defined algorithms.

Gilles Peskine 3135184cfc Merge remote-tracking branch 'upstream-crypto/development' into psa-api-beta2-merge-development
Merge the Mbed Crypto development branch a little after
mbedcrypto-1.0.0 into the PSA Crypto API 1.0 beta branch a little
after beta 2.

Summary of merge conflicts:

* Some features (psa_copy_key, public key format without
  SubjectPublicKeyInfo wrapping) went into both sides, but with a few
  improvements on the implementation side. For those, take the
  implementation side.
* The key derivation API changed considerably on the API side. This
  merge commit generally goes with the updated API except in the tests
  where it keeps some aspects of the implementation.

Due to the divergence between the two branches on key derivation and
key agreement, test_suite_psa_crypto does not compile. This will be
resolved in subsequent commits.
