x509certificate

The user has saved a .p12-file (e.g. his S/MIME certificate) on SD-Card. I want to load this certificate (or the extracted private and public key) into the AndroidKeyStore. File file = new File(pathToP12File); Certificate c = null; // TODO: convert file into something I can load into the keystore KeyStore ks = KeyStore.getInstance("AndroidKeyStore"); ks.load(null); ks.setCertificateEntry("myCertAlias", c); What's the best way to convert the file into something which can be set as a certificate entry in the keystore? It's possible to interpret the p12-file as a keystore, extract the certificate

I am trying to use the iPhone's PKI libraries to encrypt a short string (12345678), but I keep getting the error -9809 (i.e. errSSLCrypto) whenever I try to use SecKeyEncrypt. The SecureTransport.h header file describes this error simply as "underlying cryptographic error", which wasn't very meaningful. My code is as follows: - (NSData *)encryptDataWithPublicKey:(NSString *)plainText { OSStatus result = -1; NSData *plainTextData = [plainText dataUsingEncoding:NSASCIIStringEncoding]; size_t plainTextLength = [plainTextData length]; SecTrustRef trustRef; SecTrustResultType trustResult;

I want to create or obtain a certificate, create a pfx-file, load it and have IdentityServer use it. However, IdentityServer is not able to use my pfx. How to successfully create a pfx and have IdentityServer use it? I have an IdentityServer4 web solution running on localhost with ASP.Net Core. I am preparing the solution for production running on Azure, and is adding a certificate to the IdentityServer pipeline instead of the developer signing certificate. Typically this means to swap code like services.AddIdentityServer() .AddDeveloperSigningCredential() with services.AddIdentityServer()

Java 11, Spring Boot 2.1.3, Spring 5.1.5 I have a Spring Boot project in which certain endpoints are guarded by an API key. This works just fine at the moment with this code: @Component("securityConfig") @ConfigurationProperties("project.security") @EnableWebSecurity @Order(1) public class SecurityJavaConfig extends WebSecurityConfigurerAdapter { private static final Logger LOG = LoggerFactory.getLogger(SecurityJavaConfig.class); private static final String API_KEY_HEADER = "x-api-key"; private String apiKey; @Override protected void configure(HttpSecurity httpSecurity) throws Exception {

I want to use the PHP function openssl_verify() to verify the signatures of different X.509 certificates. I have all it needs (certificate, $data, $signature, $pub_key_id) except of the signature algorithm but which is stored in the certificate. My simple question is: How can I extract signature algorithm from certificates? HomeCoder Look at this question , you can do it similar, try this: private function GetCertSignatureAlgorithm($certSignatureBinary, $pubKeyResourceId) { if(false === openssl_public_decrypt($certSignatureBinary, $sigString, $pubKeyResourceId)) { return false; } if (empty(

I'm trying convert .pem to .cer using OpenSSL... openssl x509 -inform PEM -in root.pem -outform DER -out root.cer But, I don't know how to install the certificate on IIS 7.0 over Win Server 2008. I read some tutorials about it and tried to install the cert in IIS 7.0 Server Certificates -> complete certificate request -> The following error appears Cannot find the certificate request associated with

I'm developing ASP.NET 4.0 web application, and I want to read the current user certificates from X509Store. Reading the LocalMachine certificates works fine, but if I set the StoreLocation to CurrentUser, it gives me an empty collection. The following code works fine : X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine); // StoreLocation.CurrentUser store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly); I've checked my personal store (via certmgr.mmc) and I'm sure that I have the certificates. What am I missing ? ( store.Certificates is empty ) It appears that you
