rsa.setPrivateString is not a funtion

[sreeksp]

I just tried example given in read me. Can someone help whether i'm missing something else?

Actual use case is , i get the token as a param in url which is rsa encrypted. I need to decrypt it with a private certificate.

[z-hao-wang]

What's your code looks like.

There might be some encoding issue or the encrypted data isn't in the right format. I would suggest to try to compare he date you are decrypting with the encrypted by this lib.

var rsa = new RSAKey(); rsa.setPublicString(publicKey); var originText = 'sample String Value'; var encrypted = rsa.encrypt(originText);

Then compare the encrypted string with your string

[sreeksp]

The above error is resolved after removing the import and declared RSAKey as var RSAKey = require('react-native-rsa') Now i'm getting JSON parse error, unexpected identifier ''whatever the privateKey is holding". The private key i'm passing is of type string. Does your library support passing .pem file as a privateKey?

var rsa = new RSAKey();
    var privateKey = `stringValue`;
    privateKey = privateKey.toString();
    console.log(privateKey);
    rsa.setPrivateString(privateKey);
    var decrypted = rsa.decrypt(params); 
    console.log(decrypted);

[z-hao-wang]

It does not support import pem key. You will need to pass in the raw key components.

[sreeksp]

is rsa.setPrivateSting() expecting the raw key components to be in json format?

[sreeksp]

@z-hao-wang i have a pem file which holds the rsa private key. Can you help me in which format do i need to pass? or can you give a working example where you pass the raw contents of pem file to rsa.setPrivateString(). This is my code.

  var rsa = new RSAKey();
    console.log(JSON.stringify(app.privateKey));
    rsa.setPrivateString(JSON.stringify(app.privateKey));
    var decrypted = rsa.decrypt(externalUrlParams[0]);
    console.log(decrypted);

i'm getting Invalid rsa private key. But the same privateKey works in my other node application(using crypto2).

[z-hao-wang]

check the test file, it contains format. https://github.com/z-hao-wang/react-native-rsa/blob/master/__tests__/index.spec.js

As long as you can extract data with same format, you will be able to use them. So that means you can try to find some libs to extra raw data from a pem key.

This is giving the decrypted value as null. i converted the pem file to json web key. Anything i'm missing? i see that the sample you shared is a little different

[z-hao-wang]

Looks like you are using base64 encoded data. Make sure convert them to hex strings.
