The DIS version of 18013-5 now specifically says
The first encryption with a key shall use a counter value of 1. For each
following encryption the counter value shall be increased by 1.
in section '9.2.1.4 Mechanism". The previous version said
The counter value is an unsigned integer, which starts at 0 for both
the mDL and the mDL Reader. For each encryption the counter value shall
be increased by 1.
which for some strange reason was interpreted by someone to mean that
counters should start at 1.
Update our implementation to use 1 as now called for by the standard.

Having this method return null is the expected and documented behavior
when either the IC HAL or credstore isn't available.

The Identity Credential APIs provides an interface to a secure store
for user identity documents. These APIs are deliberately fairly
general and abstract. To the extent possible, specification of the
message formats and semantics of communication with credential
verification devices and Issuing Authorities (IAs) is out of scope for
these APIs.
The Identity Credential APIs rely on user authentication to protect
data elements in credentials which is implemented through
auth-tokens. This CL contains changes to CryptoObject to allow this.
