what do you recommend ?

Have you tried to generate a gpg key without a passphrase ?
I just tried, and failed, gpg keeps asking for a passphrase until you enter
one or kill it. It kept haunting me and asking for a passphrase even after
trying ctrl-c

imagine?

but what do you suggest? we can document how someone can create a key
upload it and so on. You can provide me with a url that describes a
working documentation for that, i surely do not have one. alot of
documentations are somewhat bad. Many keyservers have died recently
some existing keys like DSA seem to have some affinity to SHA1, and
SHA1 is rejected today while at the same time still default on many
setups, the one documentation i saw today to fix that DSA/SHA1 issue
requires you to have a backup as it breaks your keys and is wrong.


thx
