Packages the upstream vsql-crypto extension (hashing, HMAC, AES
encryption, password hashing and random data via OpenSSL) as a separate
snap that plugs into the villagesql snap through the content interface:
sudo snap install villagesql-crypto
sudo snap connect villagesql:extensions villagesql-crypto:extensions
sudo snap restart villagesql
sudo villagesql.mysql -uroot
-e "INSTALL EXTENSION vsql_crypto; SELECT crypto_version();"
