Java to Swift AES Encryption/Decryption porting - swift

I developed an app in android that encrypt and decrypt String using AES/CFB/ZeroBytePadding mode with Cipher initialized using ...
private byte [] hashKey = null;
private Cipher m_encChiper = null;
private Cipher m_decChiper = null;
private final String key = "012345678952";
private final byte initVector[] = {0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f};
.....
MessageDigest digest = MessageDigest.getInstance("SHA-256");
hashKey = digest.digest(key.getBytes("UTF-8"));
IvParameterSpec iv = new IvParameterSpec(initVector);
SecretKeySpec skeySpec = new SecretKeySpec(hashKey, "AES");
m_encChiper = Cipher.getInstance("AES/CFB/ZeroBytePadding");//NoPadding
m_encChiper.init(Cipher.ENCRYPT_MODE, skeySpec, iv);
m_decChiper = Cipher.getInstance("AES/CFB/ZeroBytePadding");
m_decChiper.init(Cipher.DECRYPT_MODE, skeySpec, iv);
I try to port this code in Swift using CryptoSwift...
could anyone help me especially for this 2 lines:
IvParameterSpec iv = new IvParameterSpec(initVector);
SecretKeySpec skeySpec = new SecretKeySpec(hashKey, "AES");
Thank's a lot for any help...

PKCS11Interop Hash with SHA256 and Sign with RSA in two steps

I have two applications, one that calculates the SHA-256 hash of a document and the other which makes the RSA signing.
Trying different things i came to the conclusion that making CKM_SHA256 and then making CKM_RSA_PKCS give a different result than just making the CKM_SHA256_RSA_PKCS of the document itself.
So my question is, what is the difference between this two implementations?
What information is added to the hash in CKM_SHA256_RSA_PKCS mechanism that turns in a complete different signature?

Mechanims CKM_SHA256_RSA_PKCS does following things:
Computes SHA256 hash of the data just like CKM_SHA256 does
Constructs DER encoded DigestInfo structure defined in RFC 8017
Signs DigestInfo structure with private key just like CKM_RSA_PKCS does
Several approaches are possible when it comes to construction of DER encoded DigestInfo structure:
In Pkcs11Admin application I did use BouncyCastle library:
public static byte[] CreateDigestInfo(byte[] hash, string hashOid)
{
DerObjectIdentifier derObjectIdentifier = new DerObjectIdentifier(hashOid);
AlgorithmIdentifier algorithmIdentifier = new AlgorithmIdentifier(derObjectIdentifier, null);
DigestInfo digestInfo = new DigestInfo(algorithmIdentifier, hash);
return digestInfo.GetDerEncoded();
}
In Pkcs11Interop.X509Store library I did use precomputed arrays:
/// <summary>
/// Creates DER encoded PKCS#1 DigestInfo structure defined in RFC 8017
/// </summary>
/// <param name="hash">Hash value</param>
/// <param name="hashAlgorithm">Hash algorithm</param>
/// <returns>DER encoded PKCS#1 DigestInfo structure or null</returns>
private static byte[] CreatePkcs1DigestInfo(byte[] hash, HashAlgorithmName hashAlgorithm)

PKCS#11 C_CreateObject fails with bad arguments

I have a C_CreateObject PKCS#11 API call to generate a 128 bit AES-key that fails with bad arguments.
Can anyone please help me figuring out what is wrong with the template ?
CK_OBJECT_HANDLE hKey;
CK_OBJECT_CLASS keyClass = CKO_SECRET_KEY;
CK_KEY_TYPE keyType = CKK_AES;
CK_BBOOL _true = TRUE;
CK_BBOOL _false = FALSE;
CK_BYTE key_value[] = { 0x01, 0x23, 0x45, 0x67, 0x89, 0xab, 0xcd, 0xef};
CK_ATTRIBUTE keyTemplate[] = {
{CKA_CLASS, &keyClass, sizeof(keyClass)},
{CKA_KEY_TYPE, &keyType, sizeof(keyType)},
{CKA_ENCRYPT, &_true, sizeof(_true)},
{CKA_DECRYPT, &_true, sizeof(_true)},
{CKA_TOKEN, &_true, sizeof(_true)}, /* token object */
{CKA_PRIVATE, &_false, sizeof(_false)}, /* public object */
{CKA_VALUE, key_value, sizeof(key_value)},
{CKA_LABEL, CK_VOID_PTR("key"), sizeof("key")}
};
rv = pfunc11->C_CreateObject(session, keyTemplate, sizeof (keyTemplate)/sizeof (CK_ATTRIBUTE), &hKey);
if (rv != CKR_OK) {
printf("ERROR: rv=0x%08X: C_CreateObject:\n", (unsigned int)rv);
return false;
}

Your key value is too short for AES key -- you need to provide 16 bytes (128 bits) or 32 bytes (256 bits) in key_value, e.g.:
CK_BYTE key_value[] = {
0x01, 0x23, 0x45, 0x67, 0x89, 0xab, 0xcd, 0xef,
0xcd, 0xef, 0x89, 0xab, 0x45, 0x67, 0x01, 0x23,
};
Good luck!

I tested this code from Java Card DES generator applet output is different from online-tools output. And my test environment is eclipse and java card platform.
I compiled CryptoDES.java as Java Card Project. And first, I operated cap-cryptoPack script. Next, create-cryptoPack.CryptoDES script.
But, as above console, Sample_Device returned 0x6444. I don't know problem. Please help me.

How to create list of 50 different itext colors

I'm creating pdf tables in java. Each cell has itext, portions of which I need to set the font colors depending on a substring in the cell. I know how to do everything except create a set of about 50 colors different enough from one another that all cells with a particular substring are easily spotted by the user.
Is there an a collection of colors I can use, a clever way of generating such a list?
TIA

You can use any of these names like this:
BaseColor color = WebColors.getRGBColor(name);
where name is one of the values of the keys available in NAMES, such as "aliceblue", "antiquewhite", and so on. The colors were harvested from http://en.wikipedia.org/wiki/Web_colors

Java Card - Applet selection failed

Below is DES encryption code. I am getting error 0x6999: "Applet selection failed".
package JCardDES;
import javacard.framework.*;
import javacard.security.*;
import javacardx.crypto.*;
public class JCard_DES extends Applet
{
// globals
DESKey deskey;
Cipher cipherCBC;
final short dataOffset = (short) ISO7816.OFFSET_CDATA;
static byte[] TrippleDESKey = {(byte) 0x38, (byte) 0x12, (byte) 0xA4,
(byte) 0x19, (byte) 0xC6, (byte) 0x3B, (byte) 0xE7, (byte) 0x71, (byte) 0x00, (byte) 0x12, (byte) 0x00,

(byte) 0x01, (byte) 0x01, (byte) 0x03, (byte) 0xE7, (byte) 0x71};
// constructor,
// initialization
private JCard_DES(byte bArray[], short bOffset, byte bLength)
{
try {
deskey = (DESKey) KeyBuilder.buildKey(KeyBuilder.TYPE_DES, KeyBuilder.LENGTH_DES3_3KEY, false);
cipherCBC = Cipher.getInstance(Cipher.ALG_DES_CBC_NOPAD, false);
}
catch (CryptoException e) {
ISOException.throwIt((short) ((short) 0x9000 + e.getReason()));
}
if (bArray[bOffset] == 0)
{
register();
}
else
{
register(bArray, (short)(bOffset+1), bArray[bOffset]);
}
}
// install
public static void install(byte bArray[], short bOffset, byte bLength)
{
new JCard_DES(bArray, bOffset, bLength);
}
public void process(APDU apdu)
{
byte[] buf = apdu.getBuffer();
if (selectingApplet())
{
return;
}
doTrippeDES(apdu);
}
// DES encryption
private void doTrippeDES(APDU apdu)
{
byte a[] = apdu.getBuffer();
short incomingLength = (short) (apdu.setIncomingAndReceive());
if (incomingLength != 24) ISOException.throwIt(ISO7816.SW_WRONG_LENGTH);
deskey.setKey(TrippleDESKey, (short)0);
cipherCBC.init(deskey, Cipher.MODE_ENCRYPT,new byte[]{0,0,0,0,0,0,0,0},(short)0,(short)8);
cipherCBC.doFinal(a, (short) dataOffset, incomingLength, a, (short) (dataOffset + 24));
cipherCBC.init(deskey, Cipher.MODE_DECRYPT,new byte[]{0,0,0,0,0,0,0,0},(short)0,(short)8);
cipherCBC.doFinal(a, (short) (dataOffset + 24), incomingLength, a, (short) (dataOffset + 48));
// send results
apdu.setOutgoing();
apdu.setOutgoingLength((short) 72);
apdu.sendBytesLong(a, (short) dataOffset, (short) 72);
}
}
That's strange, because without the initialization codes in try/catch block, there is no problem to select the applet.
My script file (APDU script) is
powerup;
// Select JCard_DES
0x00 0xA4 0x04 0x00 0X06 0XFC 0X74 0X41 0XA1 0X9B 0X63 0x7F;
Please guide me where i'm going wrong since i'm new to Java Card Programming
Thanks

Your command length (Lc) is incorrect. It should be 0x07 instead of 0x06.
0x00 0xA4 0x04 0x00 0X07 0XFC 0X74 0X41 0XA1 0X9B 0X63 0x7F

error code 0x6999 means applet selection failed.To determine the correctness of your aid and uniqueness.Pay attention to rules inside sometimes choose aid will appear automatically when the concept of completion.
