No. In the context of a hash, "bits of security" is a measure of how many possible outputs a hash function has, and thus, how hard it is to find an input with a given output. It's on a logarithmic scale, so each additional bit doubles the security. You can't compare the security of SHA-256, AES-128, and ECC-256.

SHA 256 Algorithm Explained by a Cyber Security Consultant

Webb22 apr. 2024 · SHA-256, which stands for secure hash algorithm 256, is a cryptographic hashing algorithm (or function) that’s used for message, file, and data integrity verification.

WebbDifferent SHA Forms. When learning about SHA forms, several different types of SHA are referenced. Examples of SHA names used are SHA-1, SHA-2, SHA-256, SHA-512, SHA-224, and SHA-384, but in actuality there are only two types: SHA-1 and SHA-2. The other larger numbers, like SHA-256, are just versions of SHA-2 that note the bit lengths of the SHA-2. WebbDigital/true orthoimage maps (D/TOMs) are one of the most important forms of national spatial data infrastructure (NSDI).
