To clarify the question, here’s our case:
We generate encrypted tokens by applying AES-CBC (256 bit) and Base64 to payload:
encrypted_token = Base64.encode(AES_CBC_256.encrypt(key, iv, payload)).
These encrypted tokens are publicly availab… Continue reading Can token decryption endpoint response codes variability lead to security vulnerabilities?

I’ve used OpenSSL to encrypt some socket communications.
I am however using some functionality from the windows API that prevents me from using OpenSSL’s opaque builtin sockets, so I am buffering through their BIO_s_mem interfaces … Continue reading Pitfalls of manual AES encryption for data transfer [migrated]
A security engineer is deploying a new wireless network for a company. The company shares office space with multiple tenants. Which of the following should the engineer configure on the wireless network to ensure that confidential data is … Continue reading Would this be EPA or AES? [closed]
I’m adding password protection/encryption support to a Python package that makes ZIP files (https://github.com/uktrade/stream-zip). I’m opting to not add ZipCrypto support, but instead add WinZip-style AES

Funny things can happen when a security researcher and an electronics engineer specializing in high-speed circuits get together. At least they did when [Limpkin] met [Roman], which resulted in two …read more Continue reading Current-Based Side-Channel Attacks, Two Ways
Let’s assume we’re running on mbed system with internal and external RAM. Dumping external RAM is much more easier for attacker on such systems when debug ports are locked.
I’m wondering if the context passed to mbedTLS APIs carries any se… Continue reading MbedTls – keeping context private?
