问题 We have face the issue while upgrading the existing application in android studio 3.6.3 Issues: ERROR: ERROR: Unable to find method 'com.android.build.gradle.internal.profile.ProfilerInitializer.init(Lorg/gradle/api/Project;)V'. Possible causes for this unexpected error include: Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network) The state of a Gradle build process (daemon) may be

问题 Is there a method to convert an image, that is loaded as a binary string, into a numpy array of size (im_height, im_width, 3)? Something like this: # read image as binary string with open(img_path, "rb") as image_file: image_string = image_file.read() # convert image string to numpy image_np = convert_binary_string_to_numpy(image_string) How would that conversion function look like? I'm working with decryption, thus I need to work with binary strings. Thanks! 回答1: import io import numpy as np

问题 I'm having communcation issues between my app and the server. I'm using RNCryptor to encrypt a message, which I then base64 encode and transfer to the server in the request. This is done in both the DATA header, and within the http body as post data. I think I'm making a mistake in how I'm converting & transferring the base64 encoded message via POST. If I receive the encrypted message via the header, it decrypts perfectly fine, every single time. However, if I take the message via the POST

问题 I am working on a project and we need to encrypt some user credentials (username, password, userId, ect.) to pass to our server. We have decided to use AES256 in order to achieve this. Doing some research on this subject it was hard to avoid noticing a project out there, RNCryptor that claims to be an easy-to-use solution to this problem. So I included the framework into my project and soon realized it was not as straight forward as I thought. I was hoping for a solution to where I could

问题 I need to asynchronously decrypt a large file with RNCryptor on iOS (so as to show a progress bar). I have found no example anywhere, and thus have tried what I guessed was right, but... what I've come up with doesn't work : the decryptor’s handler is never called, and the thread crashed with EXC_BAD_ADDRESS after sending all data at the end of the function. NSOutputStream *decryptedStream = [NSOutputStream outputStreamToFileAtPath:decryptedPath append:NO]; [decryptedStream open]; NSUInteger

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . What is the best method/approach to encrypt and base64 encode a UTF String that has a max size of 20 bytes in objective-c? I'm leaning towards Blowfish because of the 8 byte block size. Please provide some sample code? Thanks. 回答1: Yes. DES, 3DES and Blowfish have block sizes of 8

问题 The PHP API I’m calling from within my iOS app requires the payload to be encrypted in a certain customised way. I’m having troubles replicating that approach in Objective-C, with RNCryptor. Here is the PHP code used to encrypt a string: function encrypt($string) { $key = 'some-random-key'; return base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5($key), $string, MCRYPT_MODE_CBC, md5(md5($key)))); } And this how I’m trying to achieve the same encryption result in Objective-C: + (NSData*

问题 I'd like to create a framework using Cocoa Touch Framework Project in Swift. However, I'm building this framework on top of another framework called RNCryptor, which is Objective-C based. I've seen various tutorials on how to create a framework in Xcode but none has covered a framework with its own dependency. I tried to create a framework project and then using CocoaPods to manage its dependencies. However, there are errors appeared: 'Check Dependencies' Unable to run command...' So the

问题 I imported RNCryptor, which can be found here: https://github.com/rnapier/RNCryptor into my app. However, I've been getting three errors with this in the log.

问题 I'm developing an app that requires multiple passwords to access varying data areas. For example, a group of people could set up a chat that requires password authentication to view. Here's how I'm considering doing it: I have my keyword, let's say hypothetically: Banana When the user enters their password, I use RNCryptor to encrypt Banana using their entered key, and store that encrypted string to the server. Later, when someone tries to enter a password, I take the hashed value from the
