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?

Researchers have produced a collision in iOS’s built-in hash function, raising new concerns about Apple’s CSAM-scanning system — but Apple says the finding does not threaten the integrity of the ...

After reading an earlier IP/Decode post about hashing, my friend Jenny Rossman reached out to explain how law enforcement was using hash values to fight the spread of child pornography. For over a ...

The old and insecure MD5 hashing function hasn’t been used to sign SSL/TLS server certificates in many years, but continues to be used in other parts of encrypted communications protocols, including ...

In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...
