Pem.parsePemX509Certificate() cannot parse files with non-PEM content --------------------------------------------------------------------- Key: ELY-1300 URL: https://issues.jboss.org/browse/ELY-1300 Project: WildFly Elytron Issue Type: Bug Reporter: Peter Palaga Assignee: Jan Kalina Add a test like this to `PemTest`: {code} @Test public void testParsePemX509Certificate01() throws Exception { URL url = PemTest.class.getResource("/ca/certs/01.pem"); byte[] bytes = Files.readAllBytes(Paths.get(url.toURI())); assertNotNull(Pem.parsePemX509Certificate(CodePointIterator.ofUtf8Bytes(bytes))); } {code} Note that {{ca/certs/01.pem}} should start with non-PEM content {code} Certificate: Data: ... {code} followed by the PEM content: {code} -----BEGIN CERTIFICATE----- {code} Run the test {code} mvn clean test -Dtest=PemTest#testParsePemX509Certificate01 {code} Expected: Not quite sure if the parser should accept this. In any case, the following code works on Oracle/OpenJDK (while it does not on IBM JDK): {code} CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509"); InputStream is = X509EvidenceVerificationSuiteChild.class.getResourceAsStream("/ca/certs/01.pem"); Assert.assertNotNull((X509Certificate) certificateFactory.generateCertificate(is)); {code} Actual: {code} testParsePemX509Certificate01(org.wildfly.security.util.PemTest) Time elapsed: 0.116 sec <<< ERROR! java.lang.IllegalArgumentException: ELY03010: Malformed PEM content at offset 1 at org.wildfly.security.pem.Pem.parsePemContent(Pem.java:79) at org.wildfly.security.pem.Pem.parsePemX509Certificate(Pem.java:272) at org.wildfly.security.util.PemTest.testParsePemX509Certificate01(PemTest.java:57) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.maven.surefire.junit4.JUnit4Provider.execute(JUnit4Provider.java:367) at org.apache.maven.surefire.junit4.JUnit4Provider.executeWithRerun(JUnit4Provider.java:274) at org.apache.maven.surefire.junit4.JUnit4Provider.executeTestSet(JUnit4Provider.java:238) at org.apache.maven.surefire.junit4.JUnit4Provider.invoke(JUnit4Provider.java:161) at org.apache.maven.surefire.booter.ForkedBooter.invokeProviderInSameClassLoader(ForkedBooter.java:290) at org.apache.maven.surefire.booter.ForkedBooter.runSuitesInProcess(ForkedBooter.java:242) at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:121) {code}
