Xu Yaning updated DIRKRB-256:
-----------------------------
Description:
I have added a new test for encryption that input is not multiple 8 bytes. In
{{NewEncryptionTest.java}}, when the input length is not multiple of 8 bytes,
the encryption process will come up with errors. there is sth wrong with
{{paddingSize()}}, and I'll solve it in DIRKRB-257.
The following code test it.
{code}
public class NewEncryptionTest {
@Test
public void testDes3CbcSha1() throws IOException, KrbException {
testEncWith(EncryptionType.DES3_CBC_SHA1);
}
/**
* Decryption can leave a little trailing cruft. For the current
cryptosystems, this can be up to 7 bytes.
* @param inData
* @param outData
* @return
*/
private boolean compareResult(byte[] inData, byte[] outData) {
if (inData.length > outData.length || inData.length + 8 <=
outData.length) {
return false;
}
byte[] resultData = Arrays.copyOf(outData, inData.length);
if (Arrays.equals(inData, resultData)) {
return true;
} else {
return false;
}
}
private void testEncWith(EncryptionType eType) throws KrbException {
byte[] inData1 = "This is a test.\n".getBytes();
byte[] inData2 = "This is another test.\n".getBytes();
EncryptionKey key = EncryptionHandler.random2Key(eType);
EncryptedData enctryData1 = EncryptionHandler.encrypt(inData1, key,
KeyUsage.AD_ITE);
EncryptedData enctryData2 = EncryptionHandler.encrypt(inData2, key,
KeyUsage.AD_ITE);
byte[] outData1 = EncryptionHandler.decrypt(enctryData1, key,
KeyUsage.AD_ITE);
byte[] outData2 = EncryptionHandler.decrypt(enctryData2, key,
KeyUsage.AD_ITE);
if (compareResult(inData1, outData1)) {
System.out.println(eType + ": Success, inData1 & outData1 are the
same!");
} else {
System.err.println(eType + ": Failed, inData1 & outData1 are not
the same!");
}
if (compareResult(inData2, outData2)) {
System.out.println(eType + ": Success, inData2 & outData2 are the
same!");
} else {
System.err.println(eType + ": Failed, inData2 & outData2 are not

}
}
