Field Summary
 HashMapcreatedDigests
    
 ArrayListdigests
    
 ArrayListmanifestHashes
    

Constructor Summary
public  ManifestEntryVerifier(Manifest man)
     Create a new ManifestEntryVerifier object.

Method Summary
public  JarEntrygetEntry()
    
public  voidsetEntry(String name, JarEntry entry)
     Find the hashes in the manifest for this entry, save them, and set the MessageDigest objects to calculate the hashes on the fly.

     go through all the digests, calculating the final digest and comparing it to the one in the manifest.

Field Detail
createdDigests
HashMap createdDigests(Code)
the created digest objects



digests
ArrayList digests(Code)
the digests in use for a given entry



manifestHashes
ArrayList manifestHashes(Code)
the manifest hashes for the digests in use




Constructor Detail
ManifestEntryVerifier
public ManifestEntryVerifier(Manifest man)(Code)
Create a new ManifestEntryVerifier object.




Method Detail
getEntry
public JarEntry getEntry()(Code)
get the JarEntry for this object



setEntry
public void setEntry(String name, JarEntry entry) throws IOException(Code)
Find the hashes in the manifest for this entry, save them, and set the MessageDigest objects to calculate the hashes on the fly. If name is null it signifies that update/verify should ignore this entry.



toHex

convert a byte array to a hex string for debugging purposes
Parameters:
  data - the binary data to be converted to a hex string an ASCII hex string



update
public void update(byte buffer)(Code)
update the digests for the digests we are interested in



update
public void update(byte buffer, int off, int len)(Code)
update the digests for the digests we are interested in



verify
public java.security.cert.Certificate[] verify(Hashtable verifiedCerts, Hashtable sigFileCerts) throws JarException(Code)
go through all the digests, calculating the final digest and comparing it to the one in the manifest. If this is the first time we have verified this object, remove its Certs from sigFileCerts and place in verifiedCerts.
