I'm able to extract the contents via OpenSSL (e.g. the private key) "by hand". Based on the example here Get contents of a certificate I'm able to get contents of a certificate but not a *,pfx file. So how do I get the contents of a *.pfx file? Example: https://stackoverflow.com/questions/15130548/how-can-i-read-the-content-of-a-pfx-file-in-java
Note: I've installed the *.pfx file on my phone after downloading it. Now I want to access the contents to sign messages with the private key (I know how to sign but I'm not able to access the contents).
B4X:
public void checkExpire() {
try {
KeyManagerFactory kmf = javax.net.ssl.KeyManagerFactory.getInstance("SunX509");
KeyStore keystore = KeyStore.getInstance("PKCS12");
char[] password= "yourfilepassword".toCharArray();
keystore.load(new FileInputStream("filepath\filename.pfx"),password);
//keystore.load(new FileInputStream(certificate), password);
kmf.init(keystore, psswd);
Enumeration<String> aliases = keystore.aliases();
while(aliases.hasMoreElements()){
String alias = aliases.nextElement();
if(keystore.getCertificate(alias).getType().equals("X.509")){
Date expDate = ((X509Certificate) keystore.getCertificate(alias)).getNotAfter();
Date fromDate= ((X509Certificate) keystore.getCertificate(alias)).getNotBefore();
System.out.println("Expiray Date:-"+expDate );
System.out.println("From Date:-"+fromDate);
}
}
} catch (Exception e) {
e.printStackTrace();
}
