Length for AES256 symmetric encryption passphrase?

[Sam Gleske]

You're making the assumption that 32 ASCII characters can produce every
possible binary combination in 256 bits.  I don't know how AES handles
password phrases longer than 32 bytes but the key can be stronger I'd
imagine with more random data as the key.  I'm simply presuming.
