Getting "Error: Invalid encrypted text received. Decryption halted" while decryption

[email2smohanty]

I am getting "Error: Invalid encrypted text received. Decryption halted" while decryption. Please note that same encrypted value is getting decrypted successfully in one setup(vm) but its not working in another setup(vm), my _secretKey is same I have not changed any thing.

What could be the reason?

Could you give more information regarding this issue as follows.

1. The simple-crypto-js version you are using.
2. Steps to reproduce the error.

[email2smohanty]

My simple-crypto-js version is "2.2.0" in both the env.

Steps to reproduce:
Env1 where encryption and decryption is working as expected:
In this env my simple-crypto-js version is "2.2.0", node version is "10.16.0" and npm version is "6.9.0". I have one encrypted token value which is encrypted using secretKey "abc" and here encryption and decryption is working fine.

Env2 where encryption and decryption is not working as expected:
In this env my simple-crypto-js version is "2.2.0", node version is "8.17.0" and npm version is "6.14.4". While decrypting the same encrypted token value using same secretKey "abc" I am geting "Error: Invalid encrypted text received. Decryption halted"

@email2smohanty I believe your information is invalid in the Env2.

The error Invalid encrypted text received. Decryption halted. is a new kind of error that will only occurs on simple-crypto-js version 2.4.0 or newer. This error will never be thrown if you are using simple-crypto-js version 2.2.0.

Here are few things to mitigate the issue.

1. Make sure the encrypted token you trying to decrypt is really the one encrypted by simple-crypto-js.
2. If the simple-crypto-js you use to decrypt is a version prior to 2.3.0, make sure that you also use simple-crypto-js version 2.2.0 or older to do the encryption. It is because since simple-crypto-js version 2.3.0, there was a change in the encryption algorithm that breaks the decryption support of 2.2.0 or older. That means, anything encrypted with simple-crypto-js version 2.3.0 or newer will not be able to be decrypted with simple-crypto-js version 2.2.0 or older. Vice versa, anything encrypted with simple-crypto-js version 2.2.0 or older will not be able to be decrypted with simple-crypto-js version 2.3.0 or newer. Please read more about that here.

Yes you are correct my simple-crypto-js version was not correct in both the env's hence it was failing, now working so closing this issue.

Thanks for your hint and quick response.

Hey there, I have the same issue but in my case I am using version 3.0.0 to both encrypt and decrypt.
What I do is that using node I encrypt with a 64 byte key, then I save both the cipher text and the key to individual files.
For the decryption part I do it on the browser side. I make a get request using Axios to fetch my two files. I log both strings, and they are the same as the ones in the file.
I have been on this for days now. Do you want me to provide my code so you can see better?

I solved my problem it's fine

@zhamidi Could you please tell me how you fixed the issue? I am also using ^3.0.0 and facing the same issue.

[zhamidi]

@amitvchaudhary Well what I found out is that when I fetch my encrypted file with Axios, somehow there are quotes that are added to the string, so I removed them using cryptedjs.substr(0, cryptedjs.length)
But the problem was not coming from the simple-crypto library.
