- validation: CertificateValidator checks revocation, expiry, matching user ID, a valid communications encryption subkey and the algorithm policy; uses the earlier expiry when PGPainless and Bouncy Castle disagree - crypto: PgpEncryptor (ASCII armor, hidden recipients for Bcc) - mime: PgpMimeEncryptor builds RFC 3156 multipart/encrypted from the whole CRLF-canonical inner entity, keeping envelope headers in the clear - autoconfigure: validator and encryptor beans - demo: encrypts when a valid key is found, plaintext otherwise - rename groupId and Java packages to pro.thinhha.mailsender Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01G71TQ5jDETVwdUJxGAwaiT

mailsender
OpenPGP encryption for Spring Boot mail: discovers recipients' keys via Web Key Directory (WKD) and sends PGP/MIME (RFC 3156), or hands mail to an encrypting relay. See docs/PLAN.md for the design and milestone status.
Requires JDK 27 and Maven 3.9+. Built on Spring Boot 4.1.1 and PGPainless 2.0.
mvn verify

Demo app
The demo app looks up and validates the recipient's key via WKD, then sends DEMO_COUNT test mails
(default: 1 to test@thinhha.pro). With a valid key the mail is PGP/MIME-encrypted (RFC 3156); otherwise it is
sent in plaintext and a warning is logged. The policy layer (REQUIRE / OPPORTUNISTIC / PLAINTEXT, split
delivery) comes in milestone 5.
