SecureChannels: nonce length is not verified
Description
The nonce length is not verified on OPN reception (client or server), as stated by OPC UA standard (v1.03 part 4, table 10) :
This parameter shall have a length equal to key size used for the symmetric encryption algorithm that is identified by the securityPolicyUri.
Analysis
The verification may be done by SC_DeriveSymmetricKeySets
but it implies to return the dedicated status code BadNonceInvalid in this case.
