Reference Data
Reference datasets compiled by Utilavo Editorial from primary sources such as NIST and ISO. Each asset is paired with a documented methodology, citations, and a downloadable CSV.
Symmetric Cipher NIST Status 2026: Dataset by Algorithm
A consolidated reference for the symmetric ciphers exposed by Utilavo's encryption tools. Status, key and block sizes, and deprecation dates are sourced directly from NIST SP 800-131A Rev 2 and SP 800-57 Part 1 Rev 5 so the recommendation column is auditable.
PDF/A Archival Conformance Matrix: Levels 1a Through 3u
A structured comparison of the eight PDF/A conformance levels defined by ISO 19005 Parts 1 to 3, each mapped to its practical archival use case. PDF/A-4 (ISO 19005-4:2020) is not yet covered. The matrix exists because the PDF/A levels are commonly conflated, and choosing the wrong level routinely causes archive ingestion failures.
