I have a pair of RSA keys where the private key is encrypted with a passphrase. Would it be a security risk if the public and private keys are committed to version control without any further encryption (like via using Ansible Vault)?

Reading RFC3447, Section 8.2.1, primitive RSASSA-PKCS1-V1_5-SIGN requires an encoding into ASN.1/DER. Why not just sign the raw hash bytes rather then wrapping them as ASN1?
Continue reading Why does PCKS1-v1.5 signing require DER wrapping?
I am reasoning about the following scenario:
A server listening on a port
A client (always the same) that sends messages
When the server receive a message, it performs an action and then responds to client saying success or failure. The … Continue reading Authenticated connection client/server

I was thinking of using gpg4win to encrypt files I’ll upload to cloud storage services. I already use 7-zip so if I just wanted to password protect my files I could have easily done it, but I wanted to implement TLS style asymmetric encryp… Continue reading GPG4WIN Kleopatra does not require RSA secret key components to decrypt

I am building up a PKI and have 2 different chains of trust used for TLS Certificates.
1st Chain:
SHA1-Root / 2048 RSA Key ( provided by CA )
–> SHA256-Intermediate / 2048 Key ( mine )
—-> End Certificate
2nd Chain:
SHA256-Root / … Continue reading Any harm in having a SHA-384 and 3072-Key for an intermediate Certificate?
What are some of the risks when encrypting “plaintext” with a receiver’s public key?
I have been Googling for hours, and been reading in the Computer Security Principles and Practice 3rd edition.
It’s NOT similar:
In PGP, why not just encrypt message with recipient’s public key? Why the meta-encryption?
I have some confusion between the different public and private keys that are used in a TLS 1.3 connection. When a client makes a request to a server, I’ve always thought that a server’s TLS x509 certificate was passed to the client and cer… Continue reading TLS 1.3 RSA key exchange
