CrypClipFree online PGP encryption, in your browser

What is PGP encryption, and when do you need it?

PGP is a decades-old standard for encrypting a message so that only the intended recipient can read it. It is the same technology used to protect email, software releases and confidential documents. CrypClip applies it to a single block of text, in your browser, without an account or an install.

When it is worth using

Any time you need to send something through a channel you would not want to be read: a password to a colleague, a bank detail to a family member, a document reference in a shared ticketing system. Email, chat and support tools all keep copies of what passes through them. Encrypting the message first means those copies are useless to anyone without the password.

Why client-side matters

Most online encryption tools send your text to a server, encrypt it there, and send it back. At that moment the operator can read it, and so can anyone who later breaches them. CrypClip does the work in your browser using OpenPGP.js, so the unencrypted message never leaves your device. You can confirm that yourself: disconnect from the network and encrypt anyway, or watch the network tab while you do it.

What it does not do

Encryption protects a message in transit and at rest. It does not protect a compromised device, it does not hide the fact that you sent something, and it cannot rescue a weak password: the strength of a password-encrypted message is the strength of the password. It also cannot verify who sent a message, only who can read it.
