It means, Initialization Vector will stand like a plaintext? like in ECB mode?

comment How does the key schedule of Rijndael looks for keysizes other than 128 bit?
If I used a non standard key size, How can I follow the rijndael key schedule? most of the tutorials about AES is only using 128 bits of key... :(

what? I'm confused, but you said before why don't I use one of the standard sizes, i thought If I will encrypt a 128 bits of plaintext, I can used a 128 bits of key...

so therefore If I will encrypt a plaintext blocksize of 128 bits, I will use only a 32-128 bits of secret key? 192 bits, I will use a 32-192 bits of secret key? 256 bits, I will use a 32-256 bits of secret key?

What If I will used a 160 bits key? If I will encrypt a blocksize of 128 bits of plaintext?
