## What is FlowCrypt?

Simple end-to-end encryption to secure email and attachments on Gmail.

- Sets up in a few taps
- Lets you use PGP encryption by generating a private and public key directly on your iPhone or iPad
- Your keys are stored securely in iOS Keychain
- You can choose to save your key passphrase on device or enter it as needed
- Drafts are encrypted before saving to Gmail
- Send messages encrypted with password to users who don't have PGP

There are a few ways this encryption app stands out:
- Easy email encryption that just works.
- Anyone can use it. We've worked to ensure every single way possible that email encryption can be confusing has been removed, so that more people can encrypt Gmail.
- You can send encrypted attachments. Text files, powerpoint slides, excel documents, image files, any and all files and attachments can be sent privately. 
- No understanding of cryptography needed. Don’t know what a public key is? You don’t need to know to secure your email with FlowCrypt. Power users with an existing public key are also served.

Whether you have struggled with other ways to encrypt email or you are trying email encryption for the first time, you will find this a very simple secure email solution thanks to PGP.

PGP stands for Pretty Good Privacy it's the standard for secure email encryption. This Gmail end-to-end encryption app lets you encrypt Gmail messages anytime your email security and privacy matters, without having to think about it.

Most email providers don't give you the level of privacy that we should expect. That is why we created the FlowCrypt app that lets you encrypt google email without needing to learn anything new. 

Email PGP encryption has been historically a very difficult area, which few people used because there was no easy PGP solution around. If you were asked for a Public Key or a PubKey so that others can encrypt messages for you, just install FlowCrypt and you will find your new Public Key in the settings.

Also, file encryption is fully supported. To encrypt an attachment just open a compose screen, add the recipient's email, and attach a file. If they have encryption set up on their end, that's it - just send the encrypted email out. 

PGP or the OpenPGP is a standard for encrypted communication used by more than 10 million people. FlowCrypt is compatible with most OpenPGP software out there.

Looking forward to your feedback! Email us at human@flowcrypt.com as we're improving the app every day.

Happy to see the app made its debut on iOS, sadly it does not currently have SAML support so it does not work with google workspace.

*2023-01-21, version 1.2.1*
