>>>(1) a hash is always the same length (eg md5 hash = 16 bytes or 32 hex chars)
>>>(2) encryption without block cyphering (eg rc4) : the lengths will vary
>>>(3) If you use block ciphering, the lengths will vary depending on the length of the password, but all lengths will be a multiple of the block
>>>
>>>So, looking at the lengths of the encrypted passwords
>>>
>>>- if the length is constant, it's likely to be a hash
>>>- if the lengths are a multiple of something (not 1) it's likely to be a block cipher
>>>- otherwise it's encrypted, but not with a block cipher
>>>
>>>I case of passwords - since the lengths are small - it's difficult to distinguish between hash and block cipher

I am impressed.
