kandi X-RAY | jsencrypt Summary

jsencrypt is a JavaScript library. jsencrypt has no bugs, it has no vulnerabilities and it has medium support. However jsencrypt has a Non-SPDX License. You can install using 'npm i ousinka-jsencrypt' or download it from GitHub, npm.

When browsing the internet looking for a good solution to RSA Javascript encryption, there is a whole slew of libraries that basically take the fantastic work done by Tom Wu @ and then modify that code to do what they want. What I couldn’t find, however, was a simple wrapper around this library that basically uses the library practically untouched, but adds a wrapper to provide parsing of actual Private and Public key-pairs generated with OpenSSL. This library is the result of these efforts.

How to properly encode strings so to decrypt with CryptoJs in NodeJS?

Asked 2022-Jan-31 at 08:43

I am working out a custom hybrid encryption system. I've got symmetric encryption & asymmetric encryption & decryption all handled server-side. All I need to work out now is symmetric decryption.

I got some trouble because my client is sending symmetric key, iv & data all in string format (after asymmetric decryption), but CryptoJS is very touchy with it's encoding. It's also very confusing and vague as far as documentation goes- at least for a relatively new developer. I just can't figure out what encoding CryptoJS wants for each argument. I figure I should have guessed right by now, but no.

Some help I've gotten previously

I'm requesting help getting the encoding right so that I can decrypt with the following. And thanks a lot for any assistance.

You are using the wrong encoders for data, key and IV. All three are Base64 encoded (and not hex or Utf8). So apply the Base64 encoder.
The ciphertext must be passed to CryptoJS.AES.decrypt() as a CipherParams object or alternatively Base64 encoded, which is implicitly converted to a CipherParams object.

When both are fixed, the plain text is: "[\"001\",\"001\"]".

Pulling in JSEnquiry in your head tag will work just fine, but you need to allow time for it to download and parse. Calling it in the mounted hook doesn’t allow for that.

Try this in your mounted hook.

How to remove a certain text from a String in Angular, Typescript

Asked 2021-Aug-19 at 19:43

I created a simple encrypt generator, the user have to type a text to be encrypted and the public key he wants to use to encrypt his text. usually the public key comes with a -----BEGIN RSA PUBLIC KEY----- or -----BEGIN PUBLIC KEY----- and it ends with a -----END PUBLIC KEY-----. This is a problem for me, because i only want the key and remove this prefix and the "end public key" in the end of the key. What i want to know, is how can i remove the prefix and the end text from this string variable using Typescript in angular.

the method i use to encrypt is this

Library for PKCS 1.5 RSA Encryption in PHP 7

Asked 2021-Aug-07 at 13:49

Is anyone knows a way to do PKCS 1.5 RSA encryption using a public key in PHP 7 ?. Every PHP library that I tried to that, looks like replaced that encryption padding with OAEP padding because PKCS 1.5 encryption is not secure anymore. (Phpseclib equivalent to Java RSA Encryption) . Given below is PHP code I tried so far. What I am doing wrong here ?. Is there any way to accomplish this task in PHP?. I am using CodeIgniter 3 PHP framework.

ANSWER

Answered 2021-Aug-07 at 13:49

The posted Python (PyCryptodome) and JavaScript (JSEncrypt) reference codes do the following:

Generation of a timestamp (number of milliseconds elapsed since January 1, 1970 00:00:00 UTC).
Concatenation of timestamp and token in the format +.
Encryption with RSA and PKCS#1 v1.5 padding (RSAES-PKCS1-v1_5)
Base64 encoding and subsequent URL encoding

The posted PHP code uses different libraries for encryption: phpseclib (V3 and V1) and OpenSSL. The only difference from the reference code turned out to be that the timestamp is determined in seconds (instead of milliseconds), which was eventually identified as the cause of the problem.

The rest is consistent with the reference code, including the encryption with RSA and PKCS#1 v1.5 padding originally suspected as the cause of the bug, as could be easily verified by using a valid key pair and decrypting the ciphertext generated with the PHP code with a second independent application (e.g. online).

Note that phpseclib V3 specifies PKCS#1 v1.5 padding in the context of encryption with RSA::ENCRYPTION_PKCS1.

Create RSA public key and private key

Asked 2021-Jun-30 at 05:17

Im trying to make a SHA1withRSA sign/verify function on ASP.NET core using BouncyCastle library, 1st of all I need to make a keypair, I am using this page to generate the key: https://travistidwell.com/jsencrypt/demo/

However from BouncyCastle example code I found (C# Sign Data with RSA using BouncyCastle), from the Public and Private key text generated, I couldn't make the key files, which as I understand, would be a .CER file for public key and .PEM for private key.

So could you please suggest me a way to make the .CER and .PEM file? Also, I haven't found a complete example about signing SHA1withRSA using BouncyCastle library - or just core C#, I'd be so grateful if you could suggest me a complete example, thank you so much.

The linked website generates private keys in PKCS#1 format and public keys in X.509/SPKI format, each PEM encoded.

.NET Core only supports the import of PKCS#1 and X.509 keys as of version 3.0. For .NET Core 2.2, the easiest way is to apply BouncyCastle. For loading the PEM keys the PemReader of BouncyCastle can be used.

Option 1:

With BouncyCastle's DotNetUtilities class, RSAParameters instances can be derived and thus RSACryptoServiceProvider instances:

Node crypto instead of JSEncrypt for encryption with public key

Asked 2021-May-27 at 13:32

I have some public key which looks like MIIBIjANBgkqhkiG9w0BAQEFAAO... (392 chars). It used in the browser to encrypt some strings with JSEncrypt.

How can I encrypt strings with that public key using NodeJS crypto module?

I tried this:

...

ANSWER

Answered 2021-May-27 at 13:32

If the key in crypto.publicEncrypt(key, buffer) is passed as a string, then it is interpreted as PEM encoded key by default.
A PEM encoded key consists of a header line, followed by the Base64 encoded body (i.e. the Base64 encoded data of the DER encoded key), and a footer line.
In the posted code snippet, the header line is missing (and presumably the footer line as well), which causes the error.

crypto.publicEncrypt(key, buffer) uses OAEP as padding by default. JSEncrypt on the other hand only supports PKCS#1 v1.5 padding. So if the implementation should be compatible to JSEncrypt, i.e. if the ciphertext should be decryptable with JSEncrypt, then PKCS#1 v1.5 padding must be specified explicitly.

The following NodeJS code encrypts a message with the crypto module and decrypts the ciphertext with JSEncrypt:
