This record is a draft: it has not been reviewed yet and may be incomplete or wrong. Do not rely on it for compliance decisions. Help improve it (see CONTRIBUTING.md).

Digest of the SHA-224 hash function (SHA-2 family, 224 bits): a SHA-256 variant with different initial values and a truncated output. It is written as 56 hexadecimal digits. SHA3-224 digests have the same length, so the value alone does not tell them apart: use the field name or context.
