Util.getPublicKey/getPrivateKey sometimes reads a truncated DSA key #19

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Util.getPublicKey/getPrivateKey uses this code to read the DSA keys from an
InputStream:

   byte[] bytes = new byte[pubKey.available()];
   pubKey.read(bytes);
   pubKey.close();

This only works if the whole key contents are available().
It does not work if the buffer is too small.
In my case, it did not work, and only a truncated key was read.

Worst thing, this produced no error, but a "working" DSA key pair.
Of course, the signature could not be verified.

Please fix this to read the whole contents of the stream,
see for example Commons IO IOUtils.toByteArray(InputStream)
