Difference between encrypting something and hashing something
One might call the product of the hashing the hash codes of the hash sums. One difference is that hashing two different messages might produce the same hash values. … That way the recipient can compute the hash value of the file received and check that it matches the hash value. …

Are there hash algorithms with variable length output?
My question is if there is a hash-like algorithm that will produce a hash value where one can specify the length of the outcome? … So one would specify that that given any input the hash value (output) should be say 1000 bits.
For example, I would like to produce a hash value of the same length as the input. …

Hash function in PBKDF2
From what I understand, one has to choose a hash function and that the SHA might be a good choice. … (1) Is there a nicer simpler hash function that could semi-securely be used in PBKDF2? Or alternatively a simpler, but still nice way of padding a password that would be "easy" to do "by hand"? …
