n8n PGP Encrypt Only Node

This fork is intentionally reduced to one job: encrypt text or binary data with a recipient PGP public key.

Why this fork exists

The original node supported creating keys, decrypting, signing, verifying, private keys, passphrases, and detached signatures. For batch upload workflows such as encrypting a CSV before SFTP upload, those options add unnecessary failure points.

This fork removes those paths and keeps only public-key encryption.

Supported

• Encrypt text
• Encrypt binary files
• Manual recipient public key
• Recipient public key from URL
• Optional pre-encryption binary compression
• Encrypted binary output as data for SFTP upload nodes

Not supported

• Private keys
• Passphrases
• Decryption
• Signing
• Signature verification
• Detached signatures
• Key generation

Recommended binary setup

For downloaded files, use:

Input Type: Binary
Binary Property Name: data
Output Binary Property Name: data
Compression Algorithm: Uncompressed

Then point your SFTP node at binary property:

data

Public key handling

The node normalizes common public-key formatting problems before parsing:

• literal \n from JSON/env copy-paste
• Windows CRLF line endings
• accidental surrounding quotes
• extra text around the armored public key block
• common missing blank line after the BEGIN header

The key must still be a valid encryption-capable PGP public key. This node does not bypass OpenPGP cryptographic requirements; it only removes unnecessary private-key/signing/decryption logic.
