Collaborate Disseminate
I’m working on a secure app that uses the user’s master password to derive a symmetric key to encrypt all the user information. I want to add FaceId support now, and the approach I was thinking of was to generate a symmetric key on the Sec… Continue reading How to generate a Symmetric Key on the Secure Enclave of iOS devices and use it to encrypt data
Today it was time again to generate some new PGP key pairs that will be used for end-to-end-encrypted email. Now I’d like to know how exactly OpenPGP protects the private keys.
What I have understood so far is that the actual private PGP k… Continue reading How exactly does OpenGPG protect private keys?
When A communicates with B using third party KDC:
A issues a request to the KDC for a session key; the message includes the identity of A and B and a nonce, N1.
KDC responds with a message encrypted using key (Ka); the message includes th… Continue reading How does the key distribution center (KDC) distribute the session key in symmetric ecryption?
The Signal Protocol, as many of you would know, is used by many applications such as WhatsApp and Signal. These corporations, I can vouch for, would definitely use the most secure protocol they could- as WhatsApp, for example, would happil… Continue reading Why does the Signal Protocol use a symmetric key for encryption- when asymmetric keys are more secure?
