Signing test data

Test-only keys and certificates, generated for these tests with OpenSSL 3. They protect nothing. The password of every .p12 is test.

File	What
rsa-aes.p12	RSA 2048 self-signed "Test Signer RSA"; PBES2 AES-256-CBC, SHA-256 MAC (OpenSSL 3 default)
rsa-legacy.p12	the same key and certificate; RC2-40 certificates, 3DES key, SHA-1 MAC (-legacy)
ec-p256.p12	P-256 self-signed "Test Signer EC", no friendly name
ec-legacy.p12	ec-p256.p12 re-exported with -legacy (3DES, SHA-1 MAC): the format macOS security import accepts
ec-p384.p12	P-384 self-signed "Test Signer P384"; AES-128-CBC, SHA-1 MAC
chain.p12	RSA 2048 "Ada Lovelace" issued by a P-256 test root, chain included
chain-legacy.p12	chain.p12 re-exported with -legacy, for the Keychain tests
rsa.crt.pem, ca.crt.pem	the RSA certificate and the test root alone

openssl-signed.pdf is a hand-written one-page PDF with a /Contents placeholder, signed with openssl cms -sign -binary -md sha256 -outform DER -signer rsa.crt -inkey rsa.key over its byte ranges (adbe.pkcs7.detached, with OpenSSL's signing-time attribute). It checks the validator against a signature PdfCraft did not make; poppler's pdfsig reports it valid.

x509-rsa-sha1.pdf

A synthetic one-page PDF signed the legacy way (/SubFilter /adbe.x509.rsa_sha1, /Cert = rsa.crt.pem, /Contents = a DER OCTET STRING with the PKCS #1 signature of the SHA-1 digest of the byte ranges), with the key of rsa-aes.p12. Built by writing the objects with a fixed-width /ByteRange and zero-filled /Contents, patching the byte range, then openssl dgst -sha1 -sign rsa.key over the two ranges.

RSA signature variants (hex constants in tests/crypto.rs)

Over SHA-256("hello") with the key of rsa-aes.p12: openssl dgst -sha256 -sign rsa.key (standard DigestInfo); openssl pkeyutl -sign -pkeyopt rsa_padding_mode:pkcs1 over a hand-built DigestInfo without the NULL parameter, and over the bare digest; openssl dgst -sha256 -sigopt rsa_padding_mode:pss -sigopt rsa_pss_saltlen:0 -sign rsa.key.

Other algorithms (hex constants in tests/algorithms.rs)

All sign the message hello with throw-away keys, OpenSSL 3.6. RSA ones use the key of rsa-aes.p12.
