SHA-256 produces a hash of how many bits?

Explanation:
SHA-256 is a fixed-length hash function in the SHA-2 family, and its output is 256 bits long. This means every hash value produced by SHA-256 has 256 bits (32 bytes), regardless of the input size. The 256-bit digest is a design choice that provides a strong balance between security and practicality. Other variants in the SHA-2 family produce different lengths (such as 224, 384, or 512 bits), but for SHA-256 specifically, the digest length is 256 bits.
