I can help you interpret more precisely if you give me:

Why not 1000? Why not 10,000? The number 5,000 is not arbitrary. It emerges from a balance between: failed. next try with 5000 ivs

In real-world applications – like cracking a WEP (Wired Equivalent Privacy) key, recovering a corrupted TrueCrypt volume, or bruteforcing a PDF password – each IV represents a potential path through the cryptographic initialization phase. More IVs mean more chances to hit the correct decryption state. I can help you interpret more precisely if
