Let's say my subkeys are compromised, but my master keypair is safe and secure, so I revoke the old subkeys and issue new ones. With encryption keys, the results are pretty clear: I can still decrypt ...
Currently working on verifying and signing a file via GNUPG, given that I've already signed a file, given the clients the .sig and public key, is there a way for a client to verify the file without ...
I want to design a system that hinges on ECDSA. All messages are signed using the algorithm, and this is used to prevent spoofing. However, if a user were to somehow lose control of their key, they ...
I've created a new GPG key to sign a software package in a source repository with an expiration date three years from now. It seemed like a good security measure because if the key is compromised or ...
I'd like to know what it means to say "the cryptosystem C uses keys with a length of x bits". I do not understand what the bits length means... doesn't it depend on the encoding? The same word encodes ...
I was wondering if there was (and I hope there is) a standard for public key size for ECDH (Elliptic Curve Diffie-Hellman) and ECDSA (Elliptic Curve Digital Signature Algorithm) for every curve type ...
