SiteCheck
Identifiers and secrets from the Web Crypto random source: UUID v4 and v7, ULID, nanoid (size and alphabet), random passwords (length and character classes) and passphrases (words from the EFF large wordlist, CC BY 3.0 US), up to 100 per call. mode=parse validates a UUID or ULID and reports its version, variant and the time embedded in v1, v6, v7 and ULID. Nothing is stored.
