Encryption Validity

Problem Overview

• Decide if an attacker can crack an encryption within its validity period and return the encryption strength.
• Inputs: instructionCount (tests/sec), validityPeriod (sec), and an array of positive integer keys; Output: two integers [canCrack 1/0, strength].
• Strength: based on the key with the highest count of divisors from the set (divisors > 1), scaled by 10^5.
• Context: brute-force search vs. time-limited confidentiality in encryption.
• A Goldman interviews coding interview problem and common interview question.
