test: Add coverage for res_crypto

Browse Source 
We're validating the following functionality:

encrypting a block of data with RSA
decrypting a block of data with RSA
signing a block of data with RSA
verifying a signature with RSA
encrypting a block of data with AES-ECB
encrypting a block of data with AES-ECB

as well as accessing test keys from the keystore.
