∟java.security.cert.Certificate - The Certificate Class
This section describes the certificate class: java.security.cert.Certificate, which represents a signed certificate of a public key.
In the previous chapter, I learned that the "keytool" command line tool can
be used to manage certificates stored in "keystore" files.
Now I want to learn how to use java.security.cert.Certificate and java.security.KeyStore
classes to manage certificates stored in "keystore" files.
java.security.cert.Certificate is an abstract class representing common features
of different implementations of different certificate types. Its main methods
are:
getEncoded() - Returns a byte array of the encoded form of this certificate.
The encoding format used depends on the certificate type. For "X.509" type of certificates,
the encoding format will be "ASN.1 DER".
getPublicKey() - Returns the public key of signed in this certificate.
getType() - Returns the type of this certificate.
verify() - Verifies this certificate with the specified public key.
I am not sure why this method has no return value.
In JDK, there is a deprecated interface named as Certificate under a different package,
java.security.Certificate. To help the compiler to take the correct class definition,
I think I should use the full class name, java.security.cert.Certificate, in my Java programs.
