SHA

n. uncountable
C2 Proficiency US //ˈʃɑ// sha

n. Stands for Secure Hash Algorithm. A set of rules used by computers to keep information safe and secret. It turns data into a unique code so that nobody can change it without you knowing.

n. Abbreviation for Secure Hash Algorithm. A family of cryptographic hash functions designed to keep data secure by creating a unique digital fingerprint. Often used in digital signatures and data integrity checks to ensure information has not been altered.


SIMPLE

The system uses SHA to protect your password.

CONTEXTUAL

Developers often use SHA-256 to verify that a downloaded file is exactly the same as the original version on the server.

COMPLEX

While older versions like SHA-1 are now considered vulnerable to collision attacks, modern security protocols rely on the SHA-2 and SHA-3 families to maintain robust encryption standards across global networks.

Usage

Usually treated as an uncountable acronym; when referring to specific versions, it is often followed by a version number (e.g., SHA-256).
