java pfx,如何从Java中的PFX文件读取公钥[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

I am able to read private key from PFX file but not public key. I am using following code to read public key.

InputStream inStream = new FileInputStream(certFile);

CertificateFactory cf = CertificateFactory.getInstance(“X.509”);

BufferedInputStream bis = new BufferedInputStream(inStream);

// if (bis.available() > 0) {

java.security.cert.Certificate cert = cf.generateCertificate(bis);

System.out.println(“This part is not getting printed in case of PFX file”);

// }

puk = (PublicKey) cert.getPublicKey();

This code is working properly when i read from .cer file. Please help

Use the KeyStore class and treat the file as a PKCS#12 KeyStore. Use KeyStore.getInstance(“PKCS12”) to get an instance of a PKCS12 keystore.

The Javadocs for KeyStore contain sample code.
