signature

问题 I want to compose several "traits" across several modules. A function might require multiple such "traits" as its input, i.e.: type 'a x_t = < get_x : int ; .. > as 'a constraint 'a = < get_b : float ; .. > val foo : x_t -> float composing these traits manually in the interface is cumbersome and error-prone, but perfectly possible. But in an ideal world, I should be able to use the "trait's" name instead of manually composing all the required fields, i.e. write something like: type 'a x_t = <

问题 I'm currently working on a timestamp service producing PAdES-4-compliant timestamps. This is working fine with timestamps received from the Swisscom / Swisssign / QuoVadis servers. But whenever I use a timestamp received from my own timestamping authority or Signtrust, Adobe Reader (Version 11.0.06) keeps rejecting my timestamp with the German comment: "Dokument wurde nach dem Unterzeichnen verändert oder beschädigt", which means 'The document was changed or damaged after signature creation'.

问题 When verifying a signature using Signature.verify I receive an "Invalid encoding for signature" exception. When verifying same signature using Azure service, the signature is verified. I have a hash-data (SHA-256), a public key, and a signature that I'm trying to verify. The signature was received using com.microsoft.azure.keyvault.KeyVaultClient.sign method, with signing algorithm "ES256". This works (using ES256 algorithm) : com.microsoft.azure.keyvault.KeyVaultClient keyVaultClient; String

问题 When using classmethod to dynamic change the method in subclass, how to dynamic change signatures of method? example import inspect class ModelBase(object): @classmethod def method_one(cls, *args): raise NotImplementedError @classmethod def method_two(cls, *args): return cls.method_one(*args) + 1 class SubClass(ModelBase): @staticmethod def method_one(a, b): return a + b test = SubClass() try: print(inspect.signature(test.method_two)) except AttributeError: print(inspect.getargspec(test

问题 nodejs: const crypto = require(‘crypto’) const fs = require(‘fs’) var privateKey = fs.readFileSync(‘private.pem’).toString(‘utf8’) const sign = crypto.createSign(‘RSA-SHA256’); // RSA-SHA256和SHA256结果一样 sign.update(“test”, ‘acsii’) var signature = sign.sign(privateKey, ‘hex’) console.log(signature) output： 279d0ec2405e29db7024217dd19bc939b0d149a69335f52943ec42f0b40668a38b6d7d0661b71552 d61bf6a541680e4e542fa18e0bcbb860a7f57ec0fb89c3ea8e5cdce2bf6b8c71f0c1462a9cf228e9

问题 I am having problems when I distribute software I developed, the compiled .exe runs fine on my system but when parsed to others it displays the below error, on both 32 bit and 64 bit systems. I have tried many compile options, including obfuscating, building for any CPU, building for 64bit and 32, I also tried, building on other systems, all .dlls are supplied in the package, i even tired merging the .dlls that I could without breaking license agreements etc. Even registered all .dlls on the

问题 I have an app available in Pro (paid) & Free (add supported) versions. Both versions are signed with the same key store, but each one with its own key alias. Know, I'd like to develop a plugin compatible with both versions, offering data through a content provider. The data is sensitive, so I need my content provider to be accessible only from my app (both Pro & Free versions). Using a permission with the android:protectionLevel="signature" is not working, because the Free & Pro versions do

问题 I have been trying to fix an issue but failed countless times. I need to use a method, sign(), and I have the correct library imported, however its still not being recognized. I'm coding in Python and this is what I have that seems important: #importing the library from Crypto.Signature import PKCS1_PSS [...] signer = PKCS1_PSS.new(keypair) sig = PKCS1_PSS.sign(keypair) But the sign() method is the only thing in the entire code from that library that doesn't get recognized: "This inspection

问题 I'm trying to take advantage of the new signed middleware in Laravel 5.7, but for some reason the generated signed URL is returning 403 Invalid Signature. I'm using the latest Laravel Version, with PHP 7.2 This is my web.php route: Route::get('/report/{user}/{client}', function ($user, $client) { return ("El usuario es: $user y el cliente es: $client"); })->name('report.client')->middleware('signed'); and this is in my controller: $objDemo->tempURL = Url::temporarySignedRoute('report.client',

问题 I am trying to generate an AWS POST policy w/ signature in PHP, which will be sent to the client to allow uploading in the browser via javascript AJAX. I have copied the example at http://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-post-example.html I have 2 problems: I cannot generate a correctly encoded base64 string from the policy. $policy = '{ "expiration": "2013-08-06T12:00:00.000Z", "conditions": [{"bucket": "examplebucket"}, ["starts-with", "$key", "user/user1/"], {"acl": "public
