NouveauPG is the easiest to use OpenPGP client for iOS. Keep your e-mail and social media communications safe from prying eyes with OpenPGP encryption. Each message is encrypted with a unique key so it is impossible for an intercepting party to decrypt without your private keys.
NouveauPG securely and conveniently manages your private keys and also allows you to easily export your private key as plain text for storage in an e-mail account, a file, or even printed onto paper.
NouveauPG uses the clipboard import and export OpenPGP messages so it is easy to use with any other app to protect your privacy.
NouveauPG for iOS is currently on hiatus.
