As far as I know, it is bad to check-in something like a password in a version control system. However, I saw in a project that a private_key.pem file with —–BEGIN RSA PRIVATE KEY—– … content is checked in. For me this smells like … Continue reading Is it safe to check-in a RSA private key?
I’m trying to get my head around this scenario. I understand that a private key can be used for signing a message to provide authentication and public key can be used for encrypting and its corresponding private key can be used to decrypt … Continue reading Digital Signature and Encryption Process / Hierarchy
I want to generate multiple private keys and certifications in a short time. It means it is not a good idea to generate one by one. I know it can share some processes or parameters to generate multiple private keys and certificates. It can… Continue reading How to separate parameters and use the same parameters to speed up the private key and certification generation in RSA [closed]
Courses giving introduction to cryptography often refer to an example where Alice and Bob need to communicate through an evil postman, and dispose each of a lock, its key and a box in which to send the message.
The solution then given is t… Continue reading Question regarding DH/RSA/Public key cryptography [closed]
Hi,
Recently, I was studying about openssl.
I found that encrypting with a private key is allowed while decrypting with the public one isn’t, and throws an error:
unable to load Private Key or A private key is needed for this operation
—… Continue reading Encrypt with private and decrypt with public keys /Openssl

So far I can do the following. But I have no idea if it is working because I can’t see the keys. I am planning on extracting them into a char array and storing them In a struct. So I need the full encoded byte array for the private and pub… Continue reading How to generate and hex encode a ED25519 keypair using openssl 3.0 c++ [migrated]
