Example Data Table

Field	Example Value	Purpose
Plaintext Message	Quarterly cost forecast approved for distribution.	Content that will be encrypted for the recipient.
Recipient Public Key	-----BEGIN PGP PUBLIC KEY BLOCK-----	Key material used to lock the message.
Signing Key	Optional private key block	Used only when authenticity proof is needed.
Armor Output	Yes	Generates text-safe armored output for easy sharing.
Compression	ZLIB	Reduces size before encryption in supported workflows.

Formula Used

PGP encryption is a hybrid cryptography workflow rather than one simple arithmetic formula. A session key is generated first, then the message is encrypted with that symmetric key, and finally the session key is encrypted with the recipient’s public key.

Session Key: K_s = Random(n)

Ciphertext: C = E_{K_s}(M)

Wrapped Key: W = E_{K_pub}(K_s)

Signature: S = Sign_{K_priv}(H(M))

Armored Output: A = Radix64(W, C, S)

Where M is the plaintext, H(M) is the message hash, K_pub is the recipient public key, and K_priv is the optional signing private key.

Frequently Asked Questions

1. What does this tool do?

It encrypts plaintext with a recipient public key and can optionally add a signature. The result is shown in armored text for convenient copying or recordkeeping.

2. Is this real PGP encryption?

Yes. The page uses an OpenPGP library in the browser to perform public key encryption. Your message is processed client-side after the page loads.

3. Why is a public key required?

Public key encryption needs the recipient’s public key to lock the message. Only the matching private key can decrypt the protected content later.

4. When should I add a signing key?

Add a signing private key when the recipient must verify who created the message. Signing proves origin and helps detect unauthorized content changes.

5. What is ASCII armor?

ASCII armor converts binary encrypted data into text blocks. This makes it easier to paste into email, tickets, documentation, and text files.

6. Does compression improve security?

Compression mainly reduces message size before encryption. It can help transport efficiency, but the main security benefits still come from encryption and key management.

7. What does the CSV export contain?

The CSV export stores a compact record of your inputs and generated status, including message length, armor choice, compression mode, and the produced encrypted result.

8. Can this page decrypt messages too?

This version focuses on encryption and optional signing. A separate decrypt workflow should be used when you need private key input and message verification.
