Wrap armored PGP into proper PGP/MIME (RFC 2015) emails, or parse and decrypt incoming PGP/MIME content. For interop with email clients that expect the MIME-encapsulated form.
PGP/MIME is the email standard that wraps OpenPGP encrypted or signed content inside MIME multipart messages, the format Thunderbird, Apple Mail, ProtonMail, and most modern PGP-aware mail clients expect. This tool converts in both directions: take an armored PGP message, get a complete RFC 2015 MIME envelope ready to paste into an email; or paste a received MIME blob and extract the underlying PGP content.
Useful when you compose PGP messages outside an email client (in PGP Tool, GnuPG, or anywhere else) but need to deliver them via an email service that requires the MIME format. Also handy for debugging encrypted email pipelines and for parsing forwarded ciphertext blobs that arrived as raw MIME.
PGP/INLINE (the older format with armor pasted into the email body) is still supported by some clients but is being phased out. Prefer PGP/MIME for new workflows.
Frequently asked questions
What is the difference between PGP/MIME and PGP/INLINE?
PGP/INLINE puts the armored ciphertext directly into the email body. PGP/MIME wraps it in a multipart MIME structure with proper headers (Content-Type: multipart/encrypted; protocol="application/pgp-encrypted"). PGP/MIME is the modern standard.
Will my email client read the output?
Any RFC 2015–compliant client will. Thunderbird, Apple Mail, ProtonMail, K-9 Mail, and similar all handle PGP/MIME natively. Webmail clients without PGP support will show the MIME structure as raw text.
Can I sign and encrypt at the same time?
Yes — sign the body first, then encrypt the signed result. The MIME wrapper indicates both operations were performed. Most email clients show a single combined "signed and encrypted" indicator.
Why is PGP/MIME multi-part?
To preserve clean separation between the encrypted/signed payload and the protocol indicator part. MIME tools that do not understand PGP can still parse the envelope.
Does this tool send email?
No — it only formats and parses MIME content. Use any email client (or paste into Gmail compose) to actually send.
