Is their a recommended RFC standard way to sign an ECDH certificate?
Given that the ECDH Private Key is not intended for digitalSignatures it seems wrong to sign a CSR with it’s own Private Key.
It would seem logical that another trusted c… Continue reading ECDH Certificate Signing
I have asked this already on Stack Overflow, but got a suggestion to ask in this community too.
I’m working on implementing an XML encrypting / decrypting application in .NET with support for ECDH-ES because clients will use EC key pairs t… Continue reading Is XML Encryption 1.1 Key Agreement test cases decryption possible in .NET? [closed]
I’ve noted that SHA256 of CSRs for RSA keys, generated as
openssl req -new -config leaf.conf -key rsa.key rsa.csr
are always the same, given the same key and configuration. In the same time, every time I regenerate CSR for ECC (P-384) key,… Continue reading Are ECC CSR always different and if yes, why? [closed]
Does anyone know what kind of keys are being generated when you make a Fido2/Webauthn passkey? rsa2048, rsa4096, Ed25519, or something else? Just worried if its rsa2048 it might soon be crackable, at least by state actors.

Let’s assume that authentication with certificates has been well performed, next step is to generate short-term private&public ECC keys for ECDH shared key computation.
Alice: Generates keyA with RNG and calculates pubkeyA, shares pub… Continue reading Why do you need random number for ECDH shared key computation
The Subject Public Key Info field can have a value like ECDSA_P256 or ECDH_P256 when ECC is used.
Why is it not sufficient to specify "ECC_P256"? In other words, why is it not enough to specify just the curve parameters (like pri… Continue reading Why does the Public Key Info field in an X509 certificate for EC indicate the algorithm
I was talking to my friend who is building an AI startup, and his premise was Deep Learning, can somehow be used, to predict, when fed the correct data (input) and run for multiple (n; n = large) iterations, can predict break encryption, w… Continue reading Can Deep Learning predict Encryption Keys in Elliptic Curve Diffie Hellman Ephemeral
I’m setting up a client TLS CA for authenticating requests over the internet to an AWS API Gateway endpoint. It supports TLS 1.2 but not TLS 1.3, at least from what I can tell.
Is there a minimum version of TLS 1.2 for support of Ed25519 c… Continue reading What is the minimum TLS version for support of Ed25519 Keys?
When running a server, especially one with mission-critical applications, it’s common practice to use error-correcting code (ECC) memory. As the name suggests, it uses an error-correcting algorithm to continually check …read more Continue reading Error-Correcting RAM on the Desktop
Our product stores voucher data in a database.
These voucher data can be retrieved with our app to display a voucher that can be used for payments.
Obviously, these voucher data are extremely sensitive because who ever gets access to them … Continue reading Asymmetric crypto algorithm for encryption with hardware token
