encryption

问题 I am able to verify the signature by using Nodejs crypto.createVerify whereas PHP: openssl_verify always return false. Nodejs: Getting correct result const encryptKey = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'; const crypto = require('crypto'); var data = Buffer.from(JSON.stringify(vd), "utf-8"); var password = Buffer.from(encryptKey, "utf-8"); var hashPassword = crypto.createHash('sha256').update(password).digest(); var data ='oubWLpvUHAX5Z/9fmiCx8PGTqDl0

问题 I am getting error when I try to encrypt the data using crypto Module in nodejs. I have tried disabling the padding also. Error :Error: error:0406B06E:rsa routines:RSA_padding_add_none:data too large for key size Code :- const crypto = require('crypto'); const privateKey = '-----BEGIN PRIVATE KEY-----\nMIIBVQIBADANBgkqhkiG9w0BAQEFAASCAT8wggE7AgEAAkEAqPCzhHllwH/D1RWJ\noDso47Xe7N170rSBJPP7tC49wxf8OtR576SKlbHYmlbJmd2DtimNQkYhf1DbNA+G\ndlFn1QIDAQABAkEApidV58ydzp3aNRBhsz18Ebkl70BGMA1nlrh

问题 How can I encrypt a parameter variable using the encryption method Rijndael ? I would like to encrypt some parameters in order to post them in an API call. The key should be in a specific form , 1st Key + IV Key . In addition , the 1st key should have a specific format. If anyone is able to provide a code sample for this, it would be awesome. 来源： https://stackoverflow.com/questions/62569677/how-can-i-encypt-a-parameter-with-rijndael-in-c

问题 I am retrieving my azure cosmosdb/mongodb document from a custom trigger to azure functions.. But my objectId seems to be encrypted.. How to get the correct objectid.. for example ObjectId("5df88e60d588f00c32a3c9ce") is coming as ]øŽ`Õˆð2£ÉÎ or ObjectId("5df88f92d588f00c32a3c9d1") is coming as ]ø’Õˆð2£ÉÑ Is there a way to retrieve objectid in nodejs/python or any script if i give ]ø’Õˆð2£ÉÑ as input. This is my function.json used in the azure function { "scriptFile": "__init__.py", "bindings"

问题 I am writing a simple code of AES encryption. I got stuck at a part where it says decrypt() cannot be called after encrypt(). I scrapped through the internet to find the solution, but unable to do so, maybe because of the lack of proper documentation examples. I tried changing the sequence these lines, but it did not help encrypted = encrypt(message) decrypted = decrypt(encrypted) I have 2 examples Example1 from Crypto.Cipher import AES key = 'ACD310AE179CE245624BB238867CE189' message = 'this

问题 I'm trying to encrypt a file in AES-GCM mode with 'openssl' th/ command line openssl enc -aes-256-gcm -p -iv 000000000000000000000000 -K 00000000000000000000000000000000000000000000000000000000000000 -nosalt -in file.raw -out file.enc` Encryption works but I could not find a way to retrieve a resulting GCM tag. Is there a way to get it? In this document (link) I found "Note that it is now even possible to use authenticated mode like CCM or GCM" but still there is none info how to do that. Or

问题 I have to store the key into memory. So as security concern we can not store the cryptographic key into the memory directly, We need to store the key in Encrypted way. So the idea is we store the key in encrypted manner and at the time of crypto operation, just decrypt the key and use it and dispose the key. So we are using Password based encryption(PBE) define in BouncyCastle c# version Example code. The problem in code is that the password is fix here. I have to generate the password at run
