refactor(crypto): change CRYPTO_SUPPORT flag to numeric

Updated CRYPTO_SUPPORT flag to numeric to provide below
supports -
1. CRYPTO_SUPPORT = 1 -> Authentication verification only
2. CRYPTO_SUPPORT = 2 -> Hash calculation only
3. CRYPTO_SUPPORT = 3 -> Authentication verification and
                         hash calculation
