This is a question I've been wondering for a while.
Technically these two strings have the same entropy I believe:
My question is, does character encoding affect entropy?
If generated at random, do both the ASCII and binary strings have the same entropy as passwords?
If 256bits is good as an AES key, it's also good as a password right?
I guess a similar question is does hashing a 'weak' password give a lower entropy string than a 'strong' password, consider this:
Blake2B(password) = 7c863950ac93c93692995e4732ce1e1466ad74a775352ffbaaf2a4a4ce9b549d0b414a1f3150452be6c7c72c694a7cb46f76452917298d33e67611f0a42addb8 Blake2B(fkfnajkfkg%gsddg£5ER£%££££) = 03e7415fa598e9062cfd9e3cd269ca618b38b3543501e197b6c095b8749d782234e82779a2e4b489fd9c3b002734763ee3b867835e1a2232a37bf89ef8606d09
the same entropy?
If I hadn't told you the first was the hash of password and the second the hash of fkfnajkfkg%gsddg£5ER£%££££, would it change your view?
I also suppose there is a difference between brute forcing a password which is 256bits, and one which is 256 ASCII 1's or 0's, which would be more than 256bit.
