Binary search vs hash table
WebMar 9, 2024 · Here’s a brief overview of each: SHA-1: SHA-1 is a 160-bit hash function that was widely used for digital signatures and other applications. However, it is no longer considered secure due to known vulnerabilities. SHA-2: SHA-2 is a family of hash functions that includes SHA-224, SHA-256, SHA-384, and SHA-512.
