public Certificate[] getCertificates ()

Added in API level 1

Returns an array of Certificate Objects associated with this entry or null if none exists. Make sure that the everything is read from the input stream before calling this method, or else the method returns null.

This method returns all the signers' unverified chains concatenated together in one array. To know which certificates were tied to the private keys that made the signatures on this entry, see getCodeSigners() instead.

Returns
Certificate[]

public CodeSigner[] getCodeSigners ()

Added in API level 1

Returns the code signers for the digital signatures associated with the JAR file. If there is no such code signer, it returns null. Make sure that the everything is read from the input stream before calling this method, or else the method returns null.

Only the digital signature on the entry is cryptographically verified. None of the certificates in the the CertPath returned from getSignerCertPath() are verified and must be verified by the caller if needed. See CertPathValidator for more information.

Returns
CodeSigner[] an array of CodeSigner for this JAR entry.
