SHA-256 digest
A SHA-256 digest is a unique digital fingerprint generated from input data using the SHA-256 cryptographic hash algorithm.
Also known as: SHA256 hash, SHA-256 hash

SHA-256 digest
A SHA-256 digest is exactly 256 bits, or 32 bytes. Text hexadecimal representation usually occupies 64 ASCII characters.
The marked binary digest size is calibrated. Unmeasured illustration details are representative.
GPS navigation message subframe
A legacy GPS navigation-message subframe contains 300 transmitted bits, equivalent to 37.5 bytes. The fractional byte is an exact bit-count conversion, not a claim that the radio message is stored byte-aligned.

Why we use 32 B
For comparison, this page uses binary digest size. The record labels this value standard, so the stated convention rather than an inferred average controls the comparison.
