No, a key and IV give very different security properties, and you can't compensate a weak IV with a strong key, or the other way around. First of all, a small misconception: a 16-bit number can have 2 16 possible values, and combining them gives 2 16 ⋅ 2 16 = 2 32 possible values, or a 32-bit number, not a 256-bit number. snapchat modsWebJun 4, 2015 · GCM works best with a nonce of 12 bytes though. GCM converts data - includes the nonce - to a 128 bit counter for CTR mode internally. Note that increasing the IV size does not auto-magically make the algorithm more secure. If you have 256 bit input for an IV then you could use SHA-256 bit on the input and take the 128 leftmost bits instead. road bike size inchesWebAug 28, 2024 · Obviously it is some kind of conversion that I am missing expected IV length of 16 but was 24 To call it I use String encrypted = "Stack Overflow.
