Reliable, strong, safe. This is the iOS version of Guard7. Guard7 is a general purpose cryptography tool that can be used to encrypt, decrypt email and file, sign and verify files. It is the graphical frontend for the GNU Privacy Guard (GnuPG or GPG, http://www.gnupg.org) with additional features. Guard7 is an encryption and decryption system based on industry standard that can ensure the complete security of business negotiations or personal messages. It was developed to make the daily work with GnuPG simple and efficient. Why -------------------- The most difference between "public key cryptography" and normal "password protected cryptography" is that the first approach don't ask you to distribute any password to anyone or any unsafe place, e.g. email, chat app, or internet. And, you need an encryption tool that has industrial strength to protect your confidential information. Additional Features -------------------- Organise contacts in groups, then fast and efficiently organise dozens of recipients to send and receive file or email without setup recipients one by one and answer a bunch of boring questions and input repeat info again and again. Encrypt and decrypt a file just requires several taps, it's very simple, convenient and efficient. Common Tasks -------------------- a. list all contact groups, list all member of a group. b. encrypt and decrypt a file. c. set up recipients and encrypt an email, decrypt an encrypted email. d. sign and verify files. Thousands of people already benefited from the app in 2018 that year, but until today, they still..., what they are, then what they said what they doing. what the intention of the commenter is obvious. more maliciously attack, more affirmation of the app.
