I need a fast hashing function for the purpose of unique identification (not security). How many different, say, 100 character strings can I hash with md5 before hitting a collision? What about sha1?

To answer your question, I need to step through various aspects of cryptography. One type of cryptographic algorithm is called a hash function. Hash functions take a message of any length as input and ...
