SHA: Secure Hash Algorithm in Cybersecurity
One syllable, like the start of 'sharp'. Sometimes spelled out 'S-H-A'.
SHA stands for Secure Hash Algorithm. SHA is a family of cryptographic hash functions that produce fixed-length digests from variable-length input. SHA-256 and SHA-3 are the most commonly used variants today.
How SHA Is Used in Cybersecurity
Cybersecurity professionals use SHA hashes to verify file integrity and detect tampering. Incident responders compare SHA-256 hashes of malware samples against threat intelligence databases. Security engineers implement SHA-based HMAC for message authentication in APIs and protocols.
