QUESTION
I am attempting to implement simple public key cryptography with this library's RSA functions, but decryption seems to be broken.
I have two "users", Alice and Bob. Both Alice and Bob (code in separate files) create a new empty key via const key = new nodeRSA()
. Then, they both generate a 2048 bit public and private key pair via the function key.generateKeyPair(2048)
. They both then give each other their public keys by exporting them from the key with key.exportKey('pkcs8-public-pem')
and storing them into separate files and reading them in with fs. Alice then attempts to write a message to bob by passing both the string message and bob's public key into the function below
ANSWER
Answered 2019-Feb-21 at 01:11As mentioned by Maarten, the issue was that writeFileSync
was encoding my cipher text in utf8 rather than the format the cipher text was in. This resulted in reading back incorrect cipher text, causing the key or data mismatch exception. Changing the default encoding for the function to hex solved the issue.
QUESTION
I made two comboboxes. One of them depends on data from the other. When the first one selected index changes I need take the new value and use it to update the other. Here is what I have so far for the first combobox:
...ANSWER
Answered 2018-Nov-16 at 20:11It's not clear what problem you're actually having, but there are several fixes in the code below. Name: don't use string concatenation to put data into an SQL command! Also, don't try to re-use the same connection object throughout an application. Only share the connection string, as sharing the same connection object interferes with the connection pooling feature in ADO.Net. Further, the DataAdapter will handle opening and closing the connection for you, and a Using
block, rather than a Finally
block, is the best way to be sure the connection closes if an exception is thrown.

Install CompSec
You can use CompSec like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
