黑莓的AES算法

Question

我正在黑莓應用。在那個應用程序中，我想使用AES算法來加密一個字符串。黑莓手機可以使用AES算法嗎？有沒有API？在此先感謝，

Answer 1

試試這個 - 以下

useremail= CryptAes.AESEncryption(username_.getBytes()); 

CryptAes類給出 -

public class CryptAes { 
// First create the AES key based on the bytes in secretKey using keyLength bits as the length 
static AESKey keydec = new AESKey("A3$1E*81234567891111111111111111".getBytes()); 
static AESKey keyenc = new AESKey("A3$1E*81234567891111111111111111".getBytes()); 
static AESKey keyenc128 = new AESKey("A3Q1EF8123456789".getBytes()); 
static AESKey keydec128 = new AESKey("A3Q1EF8123456789".getBytes()); 

private static byte[] iv = { 0x0a, 0x01, 0x02, 0x03, 0x04, 0x0b, 0x0c, 
    0x0d, 0x0a, 0x01, 0x02, 0x03, 0x04, 0x0b, 0x0c, 0x0d }; 

public static byte[] plainText= new byte[10000]; 

public static String AESEncryption(byte[] plainText) throws CryptoException, IOException { 
     AESEncryptorEngine engine = new AESEncryptorEngine(keyenc128); 
     CBCEncryptorEngine cengine=new CBCEncryptorEngine(engine, new InitializationVector(iv)); 
     PKCS5FormatterEngine fengine = new PKCS5FormatterEngine(engine); 
     ByteArrayOutputStream output = new ByteArrayOutputStream(); 
     BlockEncryptor encryptor = new BlockEncryptor(fengine, output); 

     encryptor.write(plainText); 
     encryptor.close(); 
     byte[] encryptedData = output.toByteArray(); output.close(); 
     String st=new String(encryptedData); 

     byte[] base64 = Base64OutputStream.encode(encryptedData, 0, encryptedData.length, false, false); 

     //Base64Coder.encodeString(Byte.toString(plainText)); 
     String str = new String(base64); 

    return str; 
} 


// sampleAESDecryption 
public static String AESDecryption(byte[] cipherText, int dataLength) throws CryptoException, IOException { 

    // Create the input stream based on the ciphertext 
    ByteArrayInputStream in = new ByteArrayInputStream(cipherText, 0, dataLength); 

    // Now create the block decryptor and pass in a new instance 
    // of an AES decryptor engine with the specified block length 
    BlockDecryptor cryptoStream = new BlockDecryptor(new AESDecryptorEngine(keydec128), in); 

    byte[] T= new byte[dataLength]; 
    // Read the decrypted text from the AES decryptor stream and 
    // return the actual length read 

    int length= cryptoStream.read(T); 
    String str= new String(T); 

    int i=str.indexOf("</msg>"); 
    str=str.substring(0,i+6); 
    return str; 
} 
}

調查AESEncryptorEngine和AESDecryptorEngine（在谷歌的幫助下）。

或者你可以考慮使用充氣城堡J2ME，作爲建議here。
