SAMPLE Certificate Revocation List (DER)

Binary DER twin of the SAMPLE CRL — the exact encoding a CRL distribution point serves over HTTP. Use it to test binary CRL fetching and caching paths that never see PEM armour.

Testing contract

Expected to pass

Scenario: Fetch or load the DER CRL and compare its parsed contents with the PEM twin.
Expected result: Both encodings produce the same CRL number, update times, and revoked-serial list.

What is a .der file?

DER (Distinguished Encoding Rules) is the binary encoding of an X.509 certificate (or other ASN.1 structure) — the same data a PEM file Base64-wraps, without the text armour. A .der certificate is compact and byte-exact, common in Java keystores and Windows tooling.

How to use this file

Use an example .der certificate to test binary X.509 parsers, ASN.1 decoders, and DER-to-PEM converters, or to confirm a tool reads raw certificate bytes. Published sample certificate, not a real identity.

How to use this file for testing

“SAMPLE Certificate Revocation List (DER)” is a deterministic Novus Examples fixture for Certificate & key testing, Conversion testing. Self-signed X.509 certificates (PEM, CRT, DER), a CSR, RSA and Ed25519 keys, an SSH public key, a PKCS#12 bundle, and an htpasswd file — all published sample-only material, for testing certificate parsers, TLS tooling, keystore importers, and PEM/DER decoders.

Documented properties for this file: seed 70117 · DER (binary). Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

This is published, SAMPLE-only security material — never a real secret. Point certificate, key, or token parsers at it, test PEM/DER decoding and PKCS handling, and confirm your tooling reads the documented fields; any sample password is printed on this page.

This is a published, sample-only certificate/key. Parse it, verify the chain or signature, and test PEM↔DER conversion — never deploy it anywhere real.
