PGP Armor
Wrap binary into OpenPGP ASCII armor with a CRC-24 checksum (or unwrap an existing armored block back to bytes + headers). Doesn't encrypt or sign — that's pgp-encrypt / pgp-sign. This tool only handles the armoring envelope.
About PGP Armor
PGP Armor wraps raw binary into OpenPGP ASCII armor with a CRC-24 checksum, or unwraps an existing armored block back into bytes plus its headers. It handles only the armoring envelope, the BEGIN/END text wrapper that lets binary keys and messages travel safely through email and chat. It does not encrypt or sign anything (that's pgp-encrypt and pgp-sign), and everything runs locally in your browser.

Common uses
- Convert a binary GPG export into a pasteable ASCII-armored block for an email or wiki
- Decode an armored PGP message back to its raw bytes to inspect the underlying packets
- Verify the CRC-24 checksum on an armored block someone sent you before processing it
- Read the armor headers (Version, Comment) off a key block without a full PGP toolchain
- Re-armor binary key material that arrived as an attachment so it can be shared as text
- Round-trip a file through armor and back to confirm it survives copy-paste intact
Frequently asked questions
Does this encrypt or sign my data?
No. PGP Armor only adds or removes the ASCII-armor envelope and CRC-24 checksum. Use pgp-encrypt to encrypt or pgp-sign to sign.
What can I feed it?
Any file, since it accepts all types. In the armor direction it wraps the bytes; in the unwrap direction it reads an armored text block back to bytes and headers.
What standard does it follow?
OpenPGP ASCII armor as described in RFC 4880, including the CRC-24 checksum line.
Is my key material uploaded anywhere?
No. Armoring and de-armoring happen entirely in your browser, so sensitive bytes never leave your device.
Why is the checksum important?
The CRC-24 catches corruption introduced when a block is copied, pasted, or line-wrapped, so a tampered or truncated block can be spotted.
