Because my Usenet postings are usually signed with my Ed25519
'coffee' key, one can convert this key to PEM format, with my
hex2pem converter[1] and use this key instead, for encrypting
a message with minicrypt to me. :-)

Example:

$ echo -n 'c0ffee5a36e581eb10f60b2831b3cdb955d2e7ef680dd282a8d43ad8b84b357a' | hex2pem -p > stefan.pem

$ echo -n 'Hello World' | minicrypt stefan.pem
