Verifies that this certificate was signed using the private key that corresponds to the specified public key. This method uses the signature verification engine supplied by the specified provider. Note that the specified Provider object does not have to be registered in the provider list. This method was added to version 1.8 of the Java Platform Standard Edition. In order to maintain backwards compatibility with existing service providers, this method is no KeyStore keyStore; String alias; (X509Certificate) keyStore.getCertificate (alias) Smart code suggestions by Tabnine. } origin: prestodb / presto. public static KeyStore loadTrustStore (File certificateChainFile) throws IOException, GeneralSecurityException { KeyStore keyStore = KeyStore. getInstance ( JKS ); keyStore. load (null, null) public X509Certificate[] getPeerX509Certificates(){ if (engine == null) { return null; } try { ArrayList<X509Certificate> rc=new ArrayList<X509Certificate>(); for ( Certificate c : engine.getSession().getPeerCertificates()) { if (c instanceof X509Certificate) { rc.add((X509Certificate)c); } } return rc.toArray(new X509Certificate[rc.size()]); } catch ( SSLPeerUnverifiedException e) { return null; }

public static final X509Certificate getInstance(byte[] certData) throws CertificateException Instantiates an X509Certificate object, and initializes it with the specified byte array. The implementation (X509Certificate is an abstract class) is provided by the class specified as the value of the cert.provider.x509v1 security property To check this code, create a Keystore 'privatekey' on your system and set your own keystore password to access that keystore. Below are the examples to illustrate the getCertificate () method: Example 1: import java.security.*; import java.security.cert.*; import java.util.*; import java.io.*; public class GFG { Dim Certificate As String = Certificate.cer ' Load the certificate into an X509Certificate object. Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(Certificate) ' Get the value. Dim results As Byte() = cert.GetPublicKey() ' Display the value to the console. Dim b As Byte For Each b In results Console.Write(b) Next b End Sub End Clas

Step 2: creating the new certificate structure. Now, having available the new public key, it can be put into a new X.509 certificate structure. BC actually provides the X509v3CertificateGenerator utility class for this task, but it relies heavily on the JCE infrastructure Dim Certificate As String = Certificate.cer ' Load the certificate into an X509Certificate object. Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(Certificate) ' Get the value. Dim results As String = cert.GetPublicKeyString() ' Display the value to the console. Console.WriteLine(results) End Sub End Clas Signs the certificate with the private key of the issuer. This method uses a Signature engine from the given provider for signing the certificate. If Provider object based JCA/JCE Signature engine instantiation is not available the Java VM in use (<1.4), this method tries to get an implementation based on the provider name (if the Provider is installed within the Security Provider framework)

public static X509Certificate.KeyUsage valueOf(java.lang.String name) Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type public: virtual System::String ^ GetKeyAlgorithm(); public virtual string GetKeyAlgorithm (); abstract member GetKeyAlgorithm : unit -> string override this.GetKeyAlgorithm : unit -> string Public Overridable Function GetKeyAlgorithm As String Returns String.

Hi, when i convert the PK11InternalTokenCert to a java X509Certificate and th= en i print out the certificate the public key is in this certificate as a: = org.mozilla.jss.pkcs11.PK11RSAPublicKey@17050dc, but i want it thee i clear= text and normal I just want to import the public key into the java keystore, therefore it needs to be wrapped as certificate. For me it doesn't matter, if the certificate is valid or not, the certificate information isn't used (no TLS). So yes, in my case the certificate would be meaningless. But still my question: is it technically possible to wrap a public key into a certificate without the original. 3.1. Construction. We can easily create a keystore using keytool, or we can do it programmatically using the KeyStore API: KeyStore ks = KeyStore.getInstance (KeyStore.getDefaultType ()); Here, we use the default type, though there are a few keystore types available like jceks or pcks12

A certificate securely binds a public key to the entity that holds the corresponding private key.

Public key cryptography relies on a public and private key pair to encrypt and decrypt the content.
