2019-04-30crypto: enforce per-alg crypto key lengthBenoît Ganne2-16/+50
Crypto algorithms have different requirements on key length. As we do not support key stretching (eg. PBKDF2), user must provide the exact key length used by the algorithm. Failing that means low-level crypto functions might read garbage (eg. aes128_key_expand() will read 16-bytes, regardless of the key provided by the user).

2019-04-26crypto, ipsec: change GCM IV handlingDamjan Marion1-1/+1
- nonce construction out of salt and iv is ipsec specific so it should be handled in ipsec code - fixes GCM unit tests - GCM IV is constructed out of simple counter, per RFC4106 section 3.1 Change-Id: Ib7712cc9612830daa737f5171d8384f1d361bb61 Signed-off-by: Damjan Marion <damarion@cisco.com>
