Overview
SHA1, short for Secure Hash Algorithm 1, is a cryptographic hash function that produces a 160-bit digest, commonly displayed as 40 hexadecimal characters. Like other hashes, it is designed for one-way comparison rather than reversible decoding.
Analysts may encounter SHA1 values in file identification, malware reports, integrity checks, threat intelligence, and evidence correlation.
In this lab, you practice recognizing SHA1 digests, comparison workflows, and the difference between hash analysis and decoding encoded text.
