RFR: 8342181: Update tests to use stronger Key and Salt size

[Fernando Guallini]

Several tests currently use weak key and salt sizes. If the purpose of the tests is not to evaluate weak keys, they should be updated to use stronger keys. This PR does not intend to update the tests to use stronger algorithms.

There is no significant increase in tests run time, those still run consistently fast
