You are so right. I'm very glad that GnuPG is available now!!!

Many thanks for this explanation!
However I'm wondering why don't you make algo 1 the default algorithm,
for better compatibility with PGP?

I have now put
in my ~/.gnupg/options file; however I'm wondering whether this might
have the undesired side-effect of using algo 1 also when encrypting
to a recipient who is known to use software that can handle algo 2 also.
May blessings from the eternal God surprise and overtake you!
