I have an Crypto.Cipher.AES.AESCipher object which i would like to save in a file.
But when i try to save it to a file i alway get the following error.
pickle.PicklingError: Can't pickle '_AES' object: <_AES object at 0x0000000002320430>
I tried the following to save the object:
dill.dump(object, open("save.p", "w"))
and I also tried:
pickle.dump(object, open("save.p", "wb")) which also gives a similar error
I created the AES object with the following:
BLOCK_SIZE = 32
secret = os.urandom(BLOCK_SIZE)
cipher = AES.new(secret)
This cipher i would like to save in a file and read it out again.
Is there a way to store such objects?

I have write some code that writes keypair of public and private key in a token. From the keypair, I create pkcs10 and later generate certificate file from it. The certificate file will be inserted to the token. It all run successfully, but somehow the certificate cannot being read by CAPI or Internet Explorer. If i insert a p12 file, it run without a fuss. I suspect that the CKA_LABEL and CKA_ID is the culprit here. In p12, everything use the same name convention. From container, public key, private key, and certificate. However in my method, the container name looks like auto generated. How can i convert it to be same with CKA_ID? Down below is my code in generating keypair that save in container.
rv = g_pFunctionList->C_GenerateKeyPair(hSession,
&ck_gen_ecc,
tPubKey, sizeof(tPubKey) / sizeof(CK_ATTRIBUTE),
tPrvKey, sizeof(tPrvKey) / sizeof(CK_ATTRIBUTE),
&pkcs11_hPubKey, &pkcs11_hPrvKey);
It save in container name like
cont_4440xxxxxxxx
How to change the container name as exactly as CKA_ID ? Can anyone help?
If your cryptoki library allow it, you can rename all the objects by setting new properties of them by calling C_SetAttributeValue function.
In your case it can looks like this:
CK_ATTRIBUTE atAttr[2];
atAttr[0].type = CKA_LABEL;
atAttr[0].pValue = pLabelValue; // <-- pass here new Label value pointer
atAttr[0].ulValueLen = ulLabelLen; // <-- pass here new Label length
atAttr[1].type = CKA_ID;
atAttr[1].pValue = pIDValue; // <-- pass here new ID value pointer
atAttr[1].ulValueLen = ulIDLen; // <-- pass here new ID length
rv = g_pFunctionList->C_SetAttributeValue(hSession, pkcs11_hPubKey, atAttr, 2);
rv = g_pFunctionList->C_SetAttributeValue(hSession, pkcs11_hPrvKey, atAttr, 2);
I am a newbie in PowerBi and currently working on a POC where I need to load data from a folder or directory. Before this load, I need to check if
1) the respective folder exists
2) the file under the folder is with.csv extension.
Ex. Let suppose we have a file '/MyDoc2004/myAction.csv'.
Here first we need to check if MyDoc2004 exists and then if myAction file is with.csv extension.
Is there any way we can do this using Power Query?
1. Check if the folder exists
You can apply Folder.Contents function with the absolute path of the folder, and handle the error returned when the folder does not exist with try ... otherwise ... syntax.
let
absoluteFolderPath = "C:/folder/that/may/not/exist",
folderContentsOrError = Folder.Contents(absoluteFolderPath),
alternativeResult = """" & absoluteFolderPath & """ is not a valid folder path",
result = try folderContentsOrError otherwise alternativeResult
in
result
2. Check if the file is with .csv extension
I'm not sure what output you are expecting.
Here is a way to get the content of the file by full path including ".csv", or return an alternative result if not found.
let
absoluteFilePath = "C:/the/path/myAction.csv",
fileContentsOrError = File.Contents(absoluteFilePath),
alternativeResult = """" & absoluteFilePath & """ is not a valid file path",
result = try fileContentsOrError otherwise alternativeResult
in
result
If this is not what you are looking for, please update the question with the expected output.
Hope it helps.
So I have a set of results in Postman from a runner on a collection using some data file for iterations - I have the stored data from the runner in the Postman app on Linux, but I want to know how I can get hold of the data. There seems to be a database hidden away in the ~/.config directory (/Desktop/file__0.indexeddb.leveldb) - that looks like it has the data from the results there.
Is there anyway that I can get hold of the raw data - I want to be able to save the results from the database and not faff around with running newman or hacking a server to post the results and then save, I already have 20000 results in a collection. I want to be able to get the responseData from each post and save it to a file - I will not execute the posts again, I need to just work out a way
I've tried KeyLord, FastNoSQL (this crashes), levelDBViewer(Jar), but not having any luck here.
Any suggestions?
inline 25024 of runner.js a simple yet hack for small numbers of results I can do the following
RunnerResultsRequestListItem = __WEBPACK_IMPORTED_MODULE_2_pure_render_decorator___default()(_class = class RunnerResultsRequestListItem extends __WEBPACK_IMPORTED_MODULE_0_react__["Component"] {
constructor(props) {
super(props);
var text = props.request.response.body,
blob = new Blob([text], { type: 'text/plain' }),
anchor = document.createElement('a');
anchor.download = props.request.ref + ".txt";
anchor.href = (window.webkitURL || window.URL).createObjectURL(blob);
anchor.dataset.downloadurl = ['text/plain', anchor.download, anchor.href].join(':');
anchor.click();
it allows me to save but obviously I have to click save for now, anyone know how to automate the saving part - please add something here!
I'm going a little crazy here. I am trying to read the value of a registry string value I manually created and every time it returns a null. If I try to read the value of an existing registry string value, it returns the value just fine. Here is the code I'm using:
ManagementBaseObject rinParams = registry.GetMethodParameters("GetStringValue");
rinParams["hDefKey"] = HKEY_LOCAL_MACHINE;
rinParams["sSubKeyName"] = #"SOFTWARE\Microsoft\.NetFramework";
// rinParams["sValueName"] = "InstallRoot";
rinParams["sValueName"] = "test";
ManagementBaseObject routParams = registry.InvokeMethod("GetStringValue", rinParams, null);
if (routParams.Properties["sValue"].Value != null)
{
routput = routParams.Properties["sValue"].Value.ToString();
}
What I did was set the code to use the above code to read the value of the "InstallRoot" in the registry HKEY_LOCAL_Machine\SOFTWARE\Microsoft.NetFramework\InstallRoot which is a REG_SZ value. I get a successful read and the directory path is returned just fine. I then created another REG_SZ variable name "test" in the same .NetFramework key and commented out the "sValueName" = "InstallRoot" and replaced it with a line for "sValueName" = "test". When I run this code under the debugger, I get a return value of null.
I've tried adding keys under SOFTWARE and values in that key like SOFTWARE\Testkey and I get the same result every time. It will not let me read a key I create, it always returns null, but it seems like I can read any key that already existed. I don't understand why I'm getting this result.
An FYI, is that I am doing a remote registry read from a Windows 7 PC. My ultimate goal is to be able to add registry keys and values. I've tried to do that and I always get an error exception "Not Found" when I try that, so I'm trying to get down to the easiest thing possible, which is to read a key and even that's not working. Any ideas for what might be going on here?
This is how I'm making the remote connection to the Windows 2008r2 server to read the registry:
ConnectionOptions connectoptions = new ConnectionOptions();
connectoptions.Impersonation = ImpersonationLevel.Impersonate;
connectoptions.Authentication = AuthenticationLevel.PacketPrivacy;
connectoptions.Username = "administrator";
connectoptions.Password = **password redacted**
ManagementScope scope = new ManagementScope(#"\\" + systemIP + #"\root\default");
scope.Options = connectoptions;
ManagementClass registry = new ManagementClass(scope, new ManagementPath("StdRegProv"), null);
I am using JavaSound with Mp3SPI support.
The one I am using is JavaZoom
http://www.javazoom.net/mp3spi/mp3spi.html
When I create an AudioFileFormat from a file constructor I can get the duration of the mp3.
File file = new File("path/to/file.mp3");
AudioFileFormat format = AudioSystem.getAudioFileFormat(file);
format.properties().get("duration"); // works fine
But I have a file in memory and I cannot write it to disk...So when I create the AudioFileFormat from an InputStream I dont get the duration.
Heres my code:
ByteArrayInputStream barray = fromNetwork();
AudioFileFormat format = AudioSystem.getAudioFileFormat(barray);
format.properties().get("duration"); // does not work
But if I try to play the audio, it works fine.
Any idea how can I do that?
I used mp3agic and everything worked fine.
Mp3Agic
ByteArrayInputStream ba = IOUtil.toByteArrayInputStreamUntilTheEnd(new FileInputStream(file));
InputStream is = new InputStream(ba);
Mp3Metadata md = new Mp3Metadata(is);
