Symmetric encryption

[Przemek_198]

Hello,
Due to the preferred one-way communication I do not use TLS but I use <Symmetric encryption (Linux, Windows).> Are there any limitations of using Symmetric encryption (Linux, Windows), how much it loads the server CPU, RAM, can it be estimated somehow, ultimately I would like to connect to about 1000 , each host will have a separate secret. Will using the same secret by a group of hosts significantly reduce the load on the checkmk server? Thank you in advance for any information.

Asymmetric agent encryption with OPENSSL

Asymmetric agent encryption with OPENSSL I already wrote a How-To Article about asymmetric agent encryption with GNU GPG here: Asymmetric agent encryption with GNU PGP. Unjustly GPG has a bad reputation and is called complex and complicated, which is not really the case in my opinion. Nevertheless II provide here a secure solution using OPENSSL to encrypt agent output. This article just show a concept how OPENSSL could be used to asymmetric encryption of the agent content. It is not the final…

Asymmetric agent encryption with GNU PGP

Agent encryption with GNU PGP Here is described how to use GPG to encrypt the agent output on the monitored host and decrypt it on the monitoring servers. It is necessary to create a key with gpg and export the public key which is used for encryption. The public key must be available in the keyring of each monitored host. 1. Create a PGP key The key needs to be created at the master monitoring server under the site user . First it needs to be validated that the tty could be accessed by gpg. …

You have the benefit of asymetric encryption without two way communication.

let me know if it helps
