title: ASN1_get_object:too long
body: <p>If I call openssl like this:</p>
  
  <pre><code>openssl dgst -sha1 -verify test.pubkey -signature test.seckey test.data
  </code></pre>
  
  <p>I get this message:</p>
  
  <pre><code>...ASN1_get_object:too long:asn1_lib.c:145:
  ...ASN1_CHECK_TLEN:bad object header:tasn_dec.c:1325:
  ...ASN1_ITEM_EX_D2I:nested asn1 error:tasn_dec.c:390:Type=DSA_SIG
  </code></pre>
  
  <p>I guess a file is not valid.</p>
  
  <p>Which of the three files (test.pubkey, test.seckey, test.data) could be the invalid file?</p>
