I’ve got a few questions regarding Elliptic-curve Cryptography (ECC) Patents.
My Company runs its own Certificate Authority. Root CA and Intermediate CA Key are generated using ECC 384-Bit (secp384r1). End Entity keys are g… Continue reading Does normal use of ECC violates ECC Patents?
Does a TLS client needs to support one of the named groups (curves?) supported by the server for TLS handshake to succeed?
Longer version:
I’m running a web site using Windows Server 2016. The web site has thousands of user… Continue reading Does a TLS client needs to support one of the named groups (curves?) supported by the server for TLS handshake to succeed?
I am reading information about RSA and Eliptic Curves cryptography. Assuming that both these two algorithms have stages until two parts achieve key exchange. If an attacker eavesdrop the stages before achieving successful key… Continue reading Attack on RSA and ECC
When using GPG to sign Git commits, and as the SSH-agent, is it important to use separate sub-keys for the signing of the Git commits as it is for authentication with the SSH host of the Git server?
Does using the same sub-key for both ex… Continue reading Is it important to use separate GPG keys for signing Git commits and for SSH authentication?
We got an assignment in which we are supposed to solve the Elliptic Curve Discrete Log Problem (ECDLP) for multiple cases, one of which I describe here.
The parameters a, b, p of an Elliptic Curve are given.
The curve is in… Continue reading The meaning of order of a point in ECDLP
I’m writing reliable UDP implementation and I want it to be secure. Also, I want to make use of elliptic curve cryptography. I don’t have the proper education to really understand the math behind this kind of cryptography, bu… Continue reading Is this key exchange algorithm secure and valid?
If we have an RSA layer of encryption over some text with n bits of security, then we use an elliptic curve, say with m bits of security, how can we calculate the total bits of security with RSA(ECC(…))? Do we multiply, add… Continue reading How can I add bits of security? (e.g. RSA + ECC)
I’d like to derive an elliptic curve private key from input keying material (a master key). Is this possible?
Attempts
Node’s crypto function, crypto.generateKeyPair does not accept input keying material, and crypto.createP… Continue reading Deriving EC Private Key from input keying material
Newer versions of MariaDB (a MySQL database server fork) have a new password based auth scheme called “ed25519”. The docs are very sparse regarding how it works and what it does.

What am I missing here? !
I’ve scoured the RFC’s, and I have yet to find anything on how to determine the ECDHE key size (or any key exchan… Continue reading ECDHE_RSA_WITH_AES_128_GCM_SHA256 – How to determine ECDHE Key Length?
