Why does PEM Base64 created by `openssl pgen` not match the DER file passed in?

In experimenting with openssl on the Linux command line with elliptic curve secp256k1 I encountered a strange situation where on converting a DER private key file to PEM format using openssl pgen the Base64 in the PEM file does not match t… Continue reading Why does PEM Base64 created by `openssl pgen` not match the DER file passed in?

Is XML Encryption 1.1 Key Agreement test cases decryption possible in .NET? [closed]

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]

Why does the Public Key Info field in an X509 certificate for EC indicate the algorithm

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

Can Deep Learning predict Encryption Keys in Elliptic Curve Diffie Hellman Ephemeral

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
