I have following information:
PTK-Pairwise Transient Key: A value derived from PMK, Authenicator nonce(Anonce), Supplicant nonce(Snonce), Authenticator Address, Supplicant Address. This is used to encrypt all unicast transmission between… Continue reading How to actually calculate Pairwise Transient Key?
I think I need to set up a root CA for a small homebrew-style LAN. The immediate reason is, the number of local services and clients needing or ideally using verifiable certificates and root certs:
BSD based routers and ser… Continue reading Appropriate cert management practices when setting up a small homebrew / local CA?
There is a REST API service. An endpoint is responsible for creation of user accounts. Each user is supposed to have an RSA keypair generated and stored on a server. To protect the private keys from being read by a possible adversary, priv… Continue reading Generating RSA keypair (safety/performance) in REST service
Context assumption and aim: Using asymmetric crypto to help Alice and Bob (members belonging to the same basketball club. The club has its own servers) to communicate together without the conversation being intercepted/modif… Continue reading Are all categories of assymetric key generation applicable to all categories of assymetric key exchange?
I may have just invented a new security tool, but I would prefer to find a standard or tool for this already made. Ideas are easy, finishing is hard.
Process:
Salt (and thumbprint) is provided from a service and/or shared … Continue reading Derive Asymetric Key Pair from Password and Salt

I want to generate a pair of ECDH keys (64 bytes each), where the first 12 bytes of the public key will suit my format.
For example, if I have a unique sequence “13456789ABC” I’d like to use it as the first 12 bytes of the … Continue reading Generating partical Eliptic Curve Diffie-Hellman keys [on hold]
I want to generate a key pair with gpg2 2.1.11 and libgcrypt 1.6.5.
I use the command gpg2 –expert –full-key-gen. This allows me to choose an ECC:
Please select what kind of key you want:
(1) RSA and RSA (default)
(2) DSA and Elg… Continue reading Which Elliptic curve cryptography (ECC) algorithm to choose with GPG?
Hardware based random number generators (RNG) get their randomness from the noise around. Software based generators get this usually from user input, like moving the mouse over a screen (like TrueCrypt does).
What makes hard… Continue reading Why are hardware based random number generators considered better than software based generators?
If user one has access to user two’s public key, couldn’t user one just go through every possible private key and check if the public key extracted from the generated private key matches?
