rockaport / alice Goto Github PK

Hi @rockaport thanks for this library.

I got this error log SecretKeyFactory PBKDF2WithHmacSHA512 implementation not found
Any work-around for it?

Thanks in anticipation.

Hi, can you help me pls because the lib works only with min android 8 and I need to work with min android 6

In the meantime exclude it when adding Alice as a dependency

implementation('com.github.rockaport:alice:0.9.0') {
    exclude group: 'org.codehaus.groovy', module: 'groovy-all'
}

Hi guys, I'm following the tutorial, and here is my code

Alice alice = new Alice(new AliceContextBuilder().build());
byte[] encryptedBytes = alice.encrypt("hello".getBytes(), "password".toCharArray());

However I got this error message. ?

Hey @rockaport, what might this code look like using alice?

Hi,
I want to use your library in a project of mine and I need to get the encrypted output as a string with UTF-8 format. Is that possible?
I use that:
AliceContext aliceContext = new AliceContextBuilder() .setAlgorithm(AliceContext.Algorithm.AES) .setMode(AliceContext.Mode.CBC) // or AliceContext.Mode.CTR .setIvLength(16) .setPadding(AliceContext.Padding.PKCS5_PADDING) .setPbkdf(AliceContext.Pbkdf.PBKDF_2_WITH_HMAC_SHA_512) .setMacAlgorithm(AliceContext.MacAlgorithm.HMAC_SHA_512) .build();
And to get the output I use that:
byte[] d = alice.encrypt(toEncrypt.getBytes(), secretKey.toCharArray()); System.out.println(new String(d)); System.out.println(new String(alice.decrypt(d, secretKey.toCharArray())));
But the output looks like:
�8Ӥ�Öz�>�$����B�+4�\kLA{�R�a Bŋ����֒b�\ا� �]j�.���?�r�$j"RɫIܪ���C��>p���~�L�]��������\��R3;!p�.��T������Ѫ&�r ��TK<{>A�HN�?�07�nϳ�U�ؑ�<X������j�����YA<K�dы�BP+9�
Do you have an idea to get an output that is sharable?

You literally only use it in one place and it is EASILY replaced with a ByteArrayOutputStream.

I rewrote your the last part of your encrypt() method to not use any dependencies:

ByteArrayOutputStream output = new ByteArrayOutputStream();
    try {
      output.write(cipher.getIV());
      output.write(encryptedBytes);

      // compute the MAC if needed and append the MAC (IV || CIPHER || MAC)
      if (context.getMacAlgorithm() != AliceContext.MacAlgorithm.NONE) {
        output.write(getMac(context.getMacAlgorithm(), password).doFinal(encryptedBytes));
      }
    } catch (IOException e) {
      throw new RuntimeException(e);
    }

    return output.toByteArray();

Having it added in gradle,on run the following error is given:
`Information:Gradle tasks [:app:assembleDebug]

Any ideas? Thanks

when i encrypt the Persian characters and decrypt, result is half of original string!
original string :
plainText = "سلام امیر";
result string :
سلام

I have been trying to encrypt a zip file using different algorithms presented in the library. The file is encrypted and decrypted and when I try to to unzip it, seems like the file is corrupted...
I have tried many compression tools and seems like this is happening because of the encryption process. Have you ever faced anything like that and any ideas on what needs to be done?

When I add the following line to gradle
implementation 'com.github.rockaport:alice:0.9.0'
and building the project , I encounter the following error
Error: MethodHandle.invoke and MethodHandle.invokeExact are only supported starting with Android O (--min-api 26).

what is the problem?
