What is PGP Message Encryption?

PGP message encryption is a method of securing text using public-key cryptography. The sender encrypts a message using the recipient’s public key, and only the matching private key can decrypt it. PGP combines encryption, hashing, and digital signatures to protect message confidentiality and integrity.

How Does PGP Message Encryption Work?

1. A PGP key pair (public and private) is generated.
2. The sender encrypts the message using the recipient’s public key.
3. The message is converted into an ASCII-armored PGP block.
4. The recipient decrypts the message using their private key.

How to Encrypt a PGP Message Online

1. Generate or paste a PGP public key.
2. Enter the plaintext message you want to encrypt.
3. Click Encrypt to generate an armored PGP message.
4. Share the encrypted message securely with the recipient.

How This Online PGP Tool Works

This tool uses the openPGP.js library to perform all cryptographic operations directly in your browser. Keys are generated locally, messages are encrypted into ASCII-armored PGP format, and decryption happens without transmitting any data to external servers.

Is This Online PGP Tool Secure?

Yes. All PGP key generation, encryption, and decryption are performed locally in your browser using openPGP.js. No messages, keys, or passphrases are sent to any server, ensuring complete client-side privacy.

PGP vs RSA Encryption

While RSA is an encryption algorithm, PGP is a complete encryption system that combines RSA, symmetric encryption, hashing, and digital signatures. PGP is widely used for secure email communication and message protection. If you only need raw RSA encryption, you can also try our RSA Encryption Online Tool.
