OpenPGP V5 鍵のサンプル
OpenPGP メーリングリストに次期 OpenPGP (RFC 4880bis) の v5 パケットに対応する秘密鍵のサンプルが上がっている。
全文引用ご容赦。
Hi!
I recently implemented v5 key support in gpg. I include a sample secret
key and would be interested to see whether other implementations can
parse it, verify the signatures and that the fingerprints match. The
key is not protected but the dash lines are indented to stop MUAs from
processing the key.
Shalom-Salam,
Werner

まだ v5 パケットに対応してないので妙な表示になっているが入れ物は出来てるので，あとはコードを書くだけだ。
書くぞ書くぞ書くぞ！

SHA-3 や Bitcoin/Blockchain など新しい知見や技術要素を大幅追加。暗号技術を使うだけならこれ1冊でとりあえず無問題。
