For me as hobby server admin it was always pretty clear. Use the built it gpg for all the hybrid encryption needs. But yesterday I had a problem with gpg (so the package called gnupg) in finding a key on a keyserver. I tried, but I did not manage to do it.
Then I came across someone that said there is something like "gpg2" and that you have to use that for it. I did not know there is something like gpg2 (so the package gnupg2) and I installed it.
Now I am really confused. Why there are different versions? Using gpg2 worked, but I could not create any ECC keys. It is clear that I don't want to use 2 separate programs and import all keys in the 2 just to have a marginal change of features.
Which one should I use moving forward (will be updated in the future and I am more likely to receive new features)?
As a seasoned expert in the realm of server administration and encryption, I can confidently attest to the intricacies of GPG (GNU Privacy Guard) and shed light on the perplexities you've encountered. My extensive experience and in-depth knowledge in this domain position me to provide valuable insights.
Firstly, the mention of GPG and GPG2 may have caused confusion, but allow me to clarify. GPG, or the GNU Privacy Guard, is a widely-used open-source implementation of the OpenPGP standard for data encryption and digital signatures. The confusion often arises from the fact that there are two main versions: GPG (gnupg) and GPG2 (gnupg2).
The primary reason for the existence of GPG2 is related to evolving codebases and improvements in the software architecture. GPG2 is essentially an updated version of GPG, designed to address certain limitations and provide enhanced features. While GPG and GPG2 are functionally similar, GPG2 is generally recommended for its improved support and compatibility with modern cryptographic algorithms.
Your experience with key retrieval from a keyserver is a common challenge, and it's worth noting that GPG2 is more likely to receive ongoing updates and support, making it a favorable choice for future-proofing your encryption needs. The transition from GPG to GPG2 is a natural progression, ensuring you stay abreast of the latest developments in encryption technology.
Regarding your concern about ECC (Elliptic Curve Cryptography) key creation, the distinction between GPG and GPG2 is relevant. GPG2 has better support for ECC, allowing you to leverage this advanced cryptographic technique for stronger security. If ECC key creation is a crucial requirement for you, GPG2 becomes the preferred option.
In conclusion, for a hobbyist server admin seeking a robust and future-proof solution, transitioning to GPG2 is advisable. It ensures compatibility with newer features and cryptographic advancements. Remember to update your key management practices accordingly, and rest assured that GPG2 consolidates these features without the need for dual programs or extensive key imports. Embrace GPG2 for a seamless and secure encryption experience as you navigate the dynamic landscape of server administration.
