Class Pkcs7ExampleFixture

java.lang.Object

co.ankatech.ankasecure.sdk.examples.Pkcs7ExampleFixture

public final class Pkcs7ExampleFixture
extends Object

Classpath loader for the PKCS#7/CMS example fixture used by the data-plane migration scenarios (ExampleScenario19, ExampleScenario20).

The fixture /pkcs7/enveloped-data-sample.p7m is a small, non-sensitive BER/DER-encoded CMS EnvelopedData structure (single recipient, zero signers) produced by the QA test signer. It carries no private key material and no secret; its encrypted payload is a throwaway QA value. It lives under src/main/resources so the examples are self-contained and re-provision-safe (the reader does not need to supply a PKCS#7 file to follow the walkthrough).

Loading the recipient's private key — required to actually decrypt and convert the EnvelopedData to JWE — is a control-plane concern handled outside the data-plane SDK (see ExampleScenario20); this helper only supplies the ciphertext to analyze/convert.

Method Summary

Modifier and Type	Method	Description
static String	envelopedDataBase64()	Returns the fixture as a Base64 string, suitable for the compact-mode request fields Pkcs7AnalysisRequest.pkcs7Data / Pkcs7ConversionRequest.pkcs7Data.
static byte[]	envelopedDataBytes()	Loads the raw DER bytes of the packaged EnvelopedData fixture from the classpath.
static File	materializeToTempFile()	Materializes the fixture to a temporary File under ExampleUtil.TEMP_DIR, for the streaming APIs that take a java.io.File.

Method Details

envelopedDataBytes

public static byte[] envelopedDataBytes()

Loads the raw DER bytes of the packaged EnvelopedData fixture from the classpath.

Returns:

the fixture bytes (never null or empty)

Throws:

IllegalStateException - if the resource is missing from the classpath

UncheckedIOException - if the resource cannot be read

envelopedDataBase64

public static String envelopedDataBase64()

Returns the fixture as a Base64 string, suitable for the compact-mode request fields Pkcs7AnalysisRequest.pkcs7Data / Pkcs7ConversionRequest.pkcs7Data.

Returns:

Base64-encoded fixture bytes

materializeToTempFile

public static File materializeToTempFile()

Materializes the fixture to a temporary File under ExampleUtil.TEMP_DIR, for the streaming APIs that take a java.io.File.

Returns:

a readable temp File containing the fixture bytes

Throws:

UncheckedIOException - if the temp file cannot be written
