WebWhen you encrypt a string with AES, you get an array of bytes back. Trying to convert those bytes directly to a string (new String(cipher.doFinal(plaintextBytes))) will cause all sorts of problems.If you require the output from your encryption method to be a string, then use Base64 rather than attempting a direct conversion. In your decryption method, convert … WebMar 8, 2024 · 1 Answer. 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.
