This is a problem at the server site. It looks like the server is exclusively accepting TLS 1.2 and does not show the usual behavior when the client requests something lesser (like downgrading or sending SSL alert) but instead just closes the connection. TLS 1.2 is not supported by OpenSSL 0.9.8 and additionally your code … Read more
Check out this link it has a example code to encrypt/decrypt data using AES256CBC using EVP API. https://github.com/saju/misc/blob/master/misc/openssl_aes.c Also you can check the use of AES256 CBC in a detailed open source project developed by me at https://github.com/llubu/mpro The code is detailed enough with comments and if you still need much explanation about the API … Read more
This is a terrible answer (not very secure), but appears to be the current Microsoft official answer. Use “http.proxyStrictSSL”: false in your settings.json file. This should work to get around the issue of installing extensions inside a corporate network, but I’d recommend disabling the setting if you are going to be working from home/coffee shop … Read more

The trickiest part of this is the EVP_BytesToKey part, which has been recreated before. How to decrypt file in Java encrypted with openssl command using AES? I’ve also got an object oriented version laying around here, if you are really not up to using that C-like code. For SHA-1, use SHA-1 instead of MD5… As … Read more
